• Remove PPE immediately after handling this product. Wash the outside of gloves before removing. As soon as possible, wash thoroughly and change into clean clothing.
Environmental Hazards
Do not apply directly to water, to areas where surface water is present, or to intertidal areas below the mean high water
mark. Do not contaminate water when disposing of equipment wash water or rinsate.
Ground Water Advisory
The active ingredient in Dual Magnum has the potential to leach through soil into ground water under certain conditions
as a result of agricultural use. Use of this chemical in areas where soils are permeable, particularly where the water table
is shallow, may result in ground water contamination.
Surface Water Advisory
The active ingredient in Dual Magnum has the potential to contaminate surface water through ground spray drift. Under
some conditions, the active ingredient may also have a high potential for runoff into surface water (primarily via dissolution
in runoff water) for several months post-application. These include poorly draining or wet soils with readily visible slopes
toward adjacent surface waters, frequently flooded areas, areas overlaying extremely shallow ground water, areas with
in-field canals or ditches that drain to surface water, areas not separated from adjacent surface waters with vegetated filter
strips, and areas overlaying tile drainage systems that drain to surface water.

Dual Magnum is a selective herbicide that can be applied as a preplant surface-applied, preplant incorporated, preemergence, or postemergence treatment for control of most annual grasses and certain broadleaf weeds in corn (all types); cotton; grasses grown for seed; peanuts; beans, peas, and lentils; potatoes; safflowers; sugar beets; sunflowers; grain or forage sorghum; soybeans; soybean, immature seed; and tomatoes.
Use Site Restrictions: Do not use in nurseries, turf, or landscape plantings.
Do not apply under conditions which favor runoff or wind erosion of soil containing this product to nontarget areas.
To prevent off-site movement due to runoff or wind erosion: • Avoid treating powdery dry or light sand soils when conditions are favorable for wind erosion. Under these conditions, settle the soil surface first by rainfall or irrigation.
• Do not apply to impervious substrates, such as paved or highly compacted surfaces.
• Do not use tailwater from the first flood or furrow irrigation of treated fields to treat nontarget crops, unless at least 1/2 inch of rainfall has occurred between application and the first irrigation.
Where directions specify a Dual Magnum tank mixture with AAtrex® formulations, other brands of atrazine may be used. Follow all use rates and other use restrictions on the AAtrex or respective atrazine product label if other brands of atrazine are used.
Note: Certain states may have established rate limitations for atrazine within specific geographical areas. Consult your state
lead pesticide control agency for additional information. It is a violation of this label to deviate from state use regulations.
Precaution: Injury may occur following the use of Dual Magnum under abnormally high soil moisture conditions during
early development of the crop.
SOIL TEXTURES AND HERBICIDE RATES
Where rates are based on coarse-, medium-, or fine-textured soils, it is understood that soil textural classes are generally
categorized as follows:
Within rate ranges in the rate tables and elsewhere on this label, use the lower rate on soils relatively coarse-textured or low in organic matter; use the higher rate on soils relatively fine-textured or high in organic matter.
Dual Magnum may be applied preemergence alone, or in combination with tank mix partners specified on this label, follow-ing preplant incorporated herbicides when used according to their label use directions and restrictions, provided that such use is not prohibited on the respective labels.
Thoroughly clean sprayer or other application device before using. Dispose of cleaning solution in a responsible manner. Do not use a sprayer or applicator contaminated with any other materials, or crop damage or clogging of the application device may result.
DUAL MAGNUM APPLIED ALONE
WEEDS CONTROLLED
Dual Magnum is taken up by the shoots and/or roots of emerging weeds. This uptake results in the inhibition of shoot and
root tissue growth soon after weed germination. Because of this, Dual Magnum will not control emerged weeds. Control
weeds that are present by another means, e.g., mechanical means or by another herbicide.
If Dual Magnum is incorporated, do not exceed a 2-3 inch depth. Any tillage after the Dual Magnum incorporation and before planting may not exceed 2-3 inches, or the depth of incorporation. Dry weather following application of Dual Magnum may reduce weed control. Cultivate if weeds develop.
Where reference is made to weeds partially controlled, partial control can either mean erratic control from good to poor, or consistent control at a level below that generally considered acceptable for commercial weed control. Control of these weeds can be erratic, due partially to variable weather conditions. The following procedures may improve the control of weeds listed as partially controlled in Table 1: • Thoroughly till soil to destroy germinating and emerged weeds.
• Plant crop into moist soil immediately after tillage. If Dual Magnum is to be used preemergence, apply at planting or immediately after planting.
If available, sprinkler irrigate within 2 days after application. Apply 1/2-1 inch of water. Use lower water volume (1/2
inch) on coarse-textured soils and higher volume (1 inch) on fine-textured soils. Also, refer to the section on Center
Pivot Irrigation Application for this method of applying Dual Magnum.
If irrigation is not possible and rain does not occur within 2 days after planting and application, weed control may be decreased. Under these conditions, make a uniform, shallow cultivation as soon as weeds emerge.

Weed Resistance Management
S-metolachlor, the active ingredient in this product, is a Group 15 herbicide based on the mode of action classification
system of the Weed Science Society of America. Any weed population may contain plants naturally resistant to Group 15
herbicides. Such resistant weed plants may not be effectively managed using Group 15 herbicides but may be effectively
managed utilizing another herbicide alone or in mixtures from a different group and/or by using cultural or mechanical
practices. However, a herbicide mode of action classification by itself may not adequately address specific weeds that are
resistant to specific herbicides. Consult your local company representative, state cooperative extension service, professional
consultants or other qualified authorities to determine appropriate actions for treating specific resistant weeds.
Best Management Practices
Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one
or more herbicides is recommended. A diversified weed management program may include the use of multiple herbicides
with different modes of action and overlapping weed spectrum with or without tillage operations and/or other cultural
practices. Research has demonstrated that using the labeled rate and directions for use is important to delay the selection
for resistance. Scouting after a herbicide application is important because it can facilitate the early identification of weed
shifts and/or weed resistance and thus provide direction on future weed management practices. One of the best ways to
contain resistant populations is to implement measures to avoid allowing weeds to reproduce by seed or to proliferate
vegetatively. Cleaning equipment between sites and avoiding movement of plant material between sites will greatly aid in
retarding the spread of resistant weed seed.
PREPLANT AND ROTATIONAL CROPS SECTION
Replanted Crop Directions:
This section covers replant crops that may be planted following a lost crop that has had an application of Dual Magnum.
If a crop treated with Dual Magnum is lost, any crop on this label, or on a supplemental Dual Magnum label, may be replanted immediately provided that the rate of Dual Magnum applied to the previous crop was not greater than the labeled rate for the crop to be replanted. If the first application was banded and the replant crop is planted in the center of the untreated bands, a second banded treatment may be applied at the rate for the use-pattern for the replant crop, provided the application does not overlap the first application band.
Rotational Crop Directions:
Do not rotate to food or feed crops other than those listed below. For all crops not listed, wait at least 12 months following
the last application of Dual Magnum before planting.
Barley, oats, rye, or wheat may be planted 4 1/2 months following treatment.
Alfalfa may be planted 4 months following application. Clover may be seeded 9 months following application.

Application Timing
Dual Magnum alone or in tank mixtures with other labeled herbicides may be applied for weed control in certain crops at
various times. Refer to the crop-specific use directions section of the label to determine which of the following application
timings listed below are allowed.
Preplant Surface-Applied: For minimum-tillage or no-tillage systems only, Dual Magnum alone and some Dual Magnum
tank mixtures may be applied up to 45 days before planting certain crops. Use only split applications for treatments made
30-45 days before planting, with 2/3 the listed broadcast rate for the crop and soil texture applied initially and the remaining
1/3 at planting. Treatments less than 30 days before planting may be made either as a split or a single application. Refer to
individual crop-specific use directions section on this label to determine if early preplant surface application may be made
for that crop. If weeds are present at the time of treatment, apply in a tank mixture combination with a contact herbicide
(for example, Gramoxone® brands, Touchdown® brands, or Roundup® brands). Observe directions for use, precautions,
and restrictions on the label of the contact herbicide. To the extent possible, do not move treated soil out of the row or
move untreated soil to the surface during planting, or weed control will be diminished.
Preplant Incorporated: Apply Dual Magnum to the soil and incorporate into the top 2 inches of soil within 14 days before
planting, using a finishing disk, harrow, rolling cultivator, or similar implement capable of providing uniform 2-inch
incorporation. Use a preplant incorporated application if furrow irrigation is used or when a period of dry weather after
application is expected. If crop will be planted on beds, apply and incorporate Dual Magnum after bed formation, unless
specified otherwise.
Preemergence: Apply Dual Magnum during planting (behind the planter) or after planting, but before weeds or crops
emerge.
Postemergence: Dual Magnum will not control emerged weeds. Control weeds that are present by another means, e.g.,
mechanical means or by another herbicide.
Special Application Procedures
•
CA Only (Corn; Safflowers; Beans, Peas, and Lentils): Preplant Incorporated: Broadcast Dual Magnum alone or with tank
mix partners listed on this label to the soil and thoroughly incorporate with a disk or similar implement set to till 4-6
inches deep. For more thorough incorporation, till the soil in 2 different directions (cross-till). Crops may be planted on
flat surface or on beds. Use caution when forming the beds to ensure that only soil from the Dual Magnum treated zone
is used (i.e., do not bring untreated soil to soil surface). If the application is made to preformed beds, incorporate Dual
Magnum with a tillage implement set to till 2-4 inches deep. Use care during tilling to keep the tilled (Dual Magnum
treated) soil on the beds. Preemergence: Apply Dual Magnum after planting. Water with sprinkler or flood irrigation
within 7-10 days.
Fall Application for Spring Weed Control (Only in IA, MN, ND, SD, WI, and portions of NE and IL - See specific instruc-
tions in the Corn; Soybeans; and Beans, Peas, and Lentils sections of this label for timing of application and other
information): Do not apply to frozen ground. Use on medium and fine soils with greater than 2.5% organic matter that
will be planted to corn or soybeans the next spring. Ground may be tilled before or after application. Do not exceed a 2
to 3-inch incorporation depth if tilled after treatment. If a spring application is made, the total rate of the fall plus spring
applications must not exceed the maximum total rate for the specific crop, or illegal residues may result.
Fall Application for Italian Ryegrass Control (Corn, Cotton, Grain and Forage Sorghum, and Soybean Only – See specific
instructions in the Corn, Cotton, Grain and Forage Sorghum, and Soybean sections of this label for timing of applica-
tion and other information): Dual Magnum may be applied in the fall (September 1-December 1) for residual control
of glyphosate-resistant Italian ryegrass (Lolium multiflorum). A tillage operation may precede the application. Do not
incorporate to a depth greater than 2-3 inches if tillage follows the application of Dual Magnum. Restrictions: 1) Do not
apply Dual Magnum to frozen ground. All crops on the Dual Magnum label may be planted the following spring after
application. 2) If a spring application is made, the combined total amount of Dual Magnum applied in the fall plus the
spring must not exceed the maximum seasonal S-metolachlor rate for the specific crop planted, or illegal residues may
result. Refer to the crop sections on this label for specific directions.
Ground Application: Apply Dual Magnum alone or in tank mixtures by ground equipment in a minimum of 10 gal of spray
mixture per acre, unless otherwise specified.
Use sprayers that provide accurate and uniform application. For Dual Magnum tank mixtures with wettable powder or dry flowable formulations, use screens and strainers no finer than 50-mesh. Rinse sprayer thoroughly with clean water immediately after use.
Calculate the amount of herbicide needed for band treatment by the formula: band width in inches row width in inches per acre of fi eld For information on applying in lower volumes of carrier, see Low Carrier Application section.
For application by air or through center pivot systems, see Aerial Drift Management and Aerial Drift Reduction Advisory
Information sections.
For information on impregnating dry fertilizer, see Dry Bulk Granular Fertilizers section.
For information on application using variable-rate technologies, see Variable-Rate Application section.
LOW CARRIER APPLICATION
For Broadcast Ground Application Only
Use sprayers, such as Ag-Chem RoGator®, Hagie, John Deere Hi-Cycle™, Melroe Spra-Coupe, Tyler Patriot™, or Willmar Air
Ride®, that provide accurate and uniform application. Only water may be used as a carrier. Use screens in suction and in-line
strainers that are 50-mesh. Manufacturers may require that tip screens as fine as 100-mesh be used with some nozzles. Use
a pump with capacity to: (1) maintain up to 35-40 psi at the nozzles, and (2) provide sufficient agitation in tank to keep
mixture in suspension. Use a minimum of 5.0 gal of spray mixture per acre. To achieve best results, apply at a maximum
sprayer speed of 15 mph. Rinse sprayer thoroughly with clean water immediately after each use.
Note: Low pressure nozzles will reduce drift and increase application accuracy. Use care when using automatic rate control-
ling devices to spray the material within the rated working pressure and flow ranges of the nozzles selected. Use nozzle
screens when instructed by the manufacturer. Place all nozzles on 20-inch centers, except flooding types. Place flooding
type nozzles on 40-inch centers. When Flat Fan-type nozzles are used, use angles of 80° or 110°. Always read and follow
the manufacturer's directions for optimum setup and performance of their nozzles or tips.
AERIAL APPLICATION
Apply Dual Magnum in water alone or in tank mixtures with AAtrex, Lorox®, or TriCor® in a minimum total volume of 2.0
gal/A by aircraft. Dual Magnum may also be applied by air in combination with Balan®, Prowl®, or Treflan®. Avoid appli-
cation under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. In order to
assure that spray will be controllable within the target area when used according to label directions, make applications at a
maximum height of 10 ft, using low-drift nozzles at a maximum pressure of 40 psi, and restrict application to periods when
wind speed does not exceed 10 mph. To assure that spray will not adversely affect adjacent sensitive nontarget plants,
apply Dual Magnum alone or Dual Magnum + AAtrex by aircraft at a minimum upwind distance of 400 ft from sensitive
plants, or apply Dual Magnum, Lorox, or TriCor at a minimum upwind distance of 300 ft from sensitive plants.
Aerial Drift Management
The interaction of many equipment- and weather-related factors determine the potential for spray drift. The applicator
and the grower are responsible for considering all these factors when making decisions.
The following drift management requirements must be followed to avoid off-target drift movement from aerial applica-tions to agricultural field crops. These requirements do not apply to forestry applications, public health uses, or to applica-tions using dry formulations.
• The distance of the outermost nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor.
• Nozzles must always point backward parallel with the air stream and never be pointed downward more than 45 Where states have more stringent regulations, they must be observed.
Ensure that the applicator is familiar with and takes into account the information covered in the Aerial Drift Reduction
Advisory Information section below.
Aerial Drift Reduction Advisory Information
Information on Droplet Size
The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply
the largest droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential, but will
not prevent drift if applications are made improperly, or under unfavorable environmental conditions (see Wind, Tempera-
ture and Humidity, and Temperature Inversions).
Controlling Droplet Size
• Volume – Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce
larger droplets.
• Pressure – Do not exceed the nozzle manufacturer's maximum pressures. For many nozzle types, lower pressure produces
larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure.
• Number of nozzles – Use the minimum number of nozzles that provide uniform coverage.
• Nozzle Orientation – Orienting nozzles so that the spray is released parallel to the airstream produces larger droplets than
other orientations and is the best practice. Significant deflection from horizontal will reduce droplet size and increase drift potential.
• Nozzle Type – Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray
angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back produce the largest droplets and the lowest drift.
Application Height
Do not apply at a height greater than 10 ft above the top of the largest plants, unless a greater height is required for
aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind.
Swath Adjustment
When applications are made with a crosswind, the swath will be displaced downward. Therefore, on the upwind and down-
wind edges of the field, the applicator must compensate for this displacement by adjusting the path of the aircraft upwind.
Increase swath adjustment distance with increasing drift potential (higher wind, smaller drops, etc.).
Wind
Drift potential is lowest between wind speeds of 2-10 mph. However, many factors, including droplet size and equipment
type, determine drift potential at any given speed. If possible, avoid application below 2 mph due to variable wind direction
and high inversion potential. Note: Local terrain can influence wind patterns.
Temperature and Humidity
When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evapo-
ration. Droplet evaporation is greatest when conditions are both hot and dry.
Temperature Inversions
If possible, avoid application during a temperature inversion because drift potential is high. Temperature inversions restrict
vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. This cloud can move in unpre-
dictable directions due to the light variable winds common during inversions. Temperature inversions are characterized by
increasing temperatures with altitude and are common on nights with limited cloud cover and light to no wind. They begin
to form as the sun sets and often continue into the morning. Their presence can be indicated by ground fog; however, if
fog is not present, inversions can also be identified by the movement of smoke from a ground source or an aircraft smoke
generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inver-
sion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing.
Sensitive Areas
Apply pesticides when the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of water, known
habitat for threatened or endangered species, nontarget crops) is minimal (e.g., when wind is blowing away from the
sensitive areas).
Avoid application to humans or animals. Flagmen and loaders must avoid inhalation of spray mist and prolonged contact with skin.
CENTER PIVOT IRRIGATION APPLICATION
Dual Magnum alone or in tank mixture with other herbicides on this label, which are registered for center pivot application,
may be applied in irrigation water preemergence (after planting, but before weeds or crop emerge) at rates listed on this
label. Dual Magnum also may be applied postemergence to the crop and preemergence to weeds in crops where postemer-
gence applications are allowed on this label. Follow all restrictions (height, timing, rate, etc.) to avoid illegal residues. Apply
this product only through a center pivot irrigation system. Do not apply this product through any other type of irrigation
system. Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from nonuniform distribution
of treated water. If you have questions about calibration, contact State Extension specialists, equipment manufacturers, or
other experts. Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public
water system, unless the pesticide label-prescribed safety devices for public water systems are in place. A person knowledge-
able of the chemigation system and responsible for its operation, or under the supervision of the responsible person, shall
shut the system down and make necessary adjustments when needed.
Operating Instructions
•
The system must contain a functional check-valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water-source contamination from backflow.
The pesticide injection pipeline must contain a functional, automatic, quick-closing check-valve to prevent the flow of fluid back toward the injection pump.
The pesticide injection pipeline must also contain a functional, normally closed, solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down.
The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops.
The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected.
Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm pump or piston pump), effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock.
• Do not apply when wind speed favors drift beyond the area intended for treatment.
• Prepare a mixture with a minimum of 1 part water to 1 part herbicide(s) and inject this mixture into the center pivot system. Injecting a larger volume of a more dilute mixture per hour will usually provide more accurate calibration of metering equipment. Maintain sufficient agitation to keep the herbicide in suspension.
• Meter into irrigation water during entire period of water application.
• Apply in 1/2-1 inch of water. Use the lower water volume (1/2 inch) on coarse-textured soils and the higher volume(1 inch) on fine-textured soils. More than 1 inch of water at application may reduce weed control by moving the herbicide below the effective zone in the soil.
Precaution for center pivot applications: Where sprinkler distribution patterns do not overlap sufficiently, unacceptable weed control may result. Where sprinkler distribution patterns overlap excessively, crop injury may result. DRY BULK GRANULAR FERTILIZERS
Many dry bulk granular fertilizers may be impregnated or coated with Dual Magnum alone or selected Dual Magnum tank
mixtures which are registered for preplant incorporated or preplant surface applications which are used to control weeds
in crops on the Dual Magnum label and are not prohibited from use on dry bulk granular fertilizers.
When applying Dual Magnum or Dual Magnum mixtures with dry bulk granular fertilizers, follow all directions for use and precautions on the respective product labels, regarding target crops, rates per acre, soil texture, application methods (including timing of application), and rotational crops.
All individual state regulations relating to dry bulk granular fertilizer blending, registration, labeling, and application are the responsibility of the individual and/or company selling the herbicide/fertilizer mixture.
Prepare the herbicide/fertilizer mixtures by using any closed drum, belt, ribbon, or other commonly used dry bulk fertilizer blender. Nozzles used to spray Dual Magnum and Dual Magnum mixtures onto the fertilizer must be placed to provide uniform spray coverage. Use care to aim the spray directly onto the fertilizer only and to avoid spraying the walls of the blender.
If the herbicide/fertilizer mixture is too wet, add a highly absorptive material, such as Agsorb® or Celatom MP-79®, or similar granular clay or diatomaceous earth materials, to obtain a dry, free-flowing mixture. Add absorptive materials only after the herbicide has been thoroughly blended into the fertilizer mixture. Best application results will be obtained by using a granule of 6/30 particle size or of a size similar to that of the fertilizer material being used. Generally, less than 2% by weight of absorptive material will be needed. Avoid using more than 5% absorptive material by weight.
Calculate amounts of Dual Magnum, AAtrex, AAtrex + Princep®, Balance® Pro, Princep, TriCor, or Sonalan® by the follow-ing formula: pt/A of liquid or pt of liquid or fl owable lb of fertilizer per acre fl owable product product per ton of fertilizer lb of dry product lb of fertilizer per acre per ton of fertilizer Pneumatic (Compressed Air) Application (Dual Magnum Alone): High humidity, high urea concentrations, low fertilizer use
rates, and dusty fertilizer may cause fertilizer mixture to build up or plug the distributor head, air tubes, or nozzle deflector
plates. To minimize buildup, premix Dual Magnum with Exxon Aromatic 200 at a rate of 1.0-4.0 pt/gal of Dual Magnum.
Aromatic 200 is a noncombustible/nonflammable petroleum product. Aromatic 200 may be used in either a fertilizer blender
or through direct injection systems. Avoid drying agents when using Aromatic 200.
Precautions: (1) Mixtures of Dual Magnum and Aromatic 200 must be used on dry fertilizer only. Poor results or crop injury
may result if these mixtures are used in water or liquid fertilizer solutions for spraying applications. (2) When impregnating
Dual Magnum in a blender before application, a drier mixture can be attained by substituting a drying agent for Aromatic
200. Agsorb FG or drying agents of 6/30 particle size will provide best results. (3) When possible, avoid drying agents when
using On-The-Go impregnation equipment.
Precautions: To avoid potential for explosion, (1) Do not impregnate Dual Magnum or Dual Magnum mixtures on
ammonium nitrate, potassium nitrate, or sodium nitrate, either alone or in blends with other fertilizers. (2) Do not use
Dual Magnum or Dual Magnum mixtures on straight limestone, since absorption will not be achieved. Fertilizer blends
containing limestone can be impregnated.
Application
Apply 200-700 lb of the herbicide/fertilizer mixture per acre. For best results, apply the mixture uniformly to the soil with
properly calibrated equipment immediately after blending. Uniform application of the herbicide/fertilizer mixture is
essential to prevent possible crop injury. Nonuniform application may also result in unsatisfactory weed control. In areas
where conventional tillage is practiced, a shallow incorporation of the mixture into the soil may improve weed control.
On fine- or medium-textured soils in areas where soil incorporation is not planned, i.e., reduced tillage situations or in
some conventional till situations, make applications approximately 30 days before planting to allow moisture to move the
herbicide/fertilizer mixture into the soil. On coarse-textured soils, make applications approximately 14 days prior to planting.
Precaution: To avoid crop injury, do not use the herbicide/fertilizer mixture on crops where bedding occurs.
Dual Magnum Alone: Mix Dual Magnum with water or fluid fertilizer and apply as a spray. Fill the spray tank 1/2-3/4 full
with water or fluid fertilizer, add the proper amount of Dual Magnum, then add the rest of the water or fluid fertilizer.
Provide sufficient agitation during mixing and application to maintain a uniform emulsion.
Tank Mixtures: Fill the spray tank 1/4 full with water, and start agitation; add 2,4-D, AAtrex, Balance Pro, Balan, Banvel®,
Basagran®, Butoxone®, Butyrac®, Canopy®, Caparol® 4L, Cotoran®, Eptam®, Liberty® Herbicide, Liberty ATZ Herbicide,
Lorox, Marksman®, MSMA, Princep, Prowl, Pursuit®, AAtrex + Princep, Sonalan, Treflan, or TriCor and allow it to become
dispersed; then add Dual Magnum; then add a Gramoxone brand, Landmaster® BW, Touchdown, or Roundup (glyphosate
products) if these products are being used; and finally the rest of the water. For tank mixtures with AAtrex, Balance, Banvel,
Canopy, Caparol 4L, Cotoran*, Eptam, Lorox, Marksman, Princep, Prowl*, Pursuit, AAtrex + Princep, Sonalan, Treflan, or
TriCor fluid fertilizers may replace all or part of the water as carrier, except in the AAtrex postemergence and the Banvel
postemergence tank mixes. For tank mixtures with AAtrex, see additional mixing instructions on the AAtrex label. For each
mixture, check compatibility with fluid fertilizer, as described below, before mixing in spray tank. For all tank mixtures,
agitate during mixing and application to maintain a uniform suspension.
* See Special Mixing Instructions for tank mixtures with Cotoran and with AAtrex or Princep + Prowl under the appropriate
tank mixture section.
For directions on how to conduct a compatibility test, see the Compatibility Test section.
COMPATIBILITY TEST
To achieve best results, conduct a jar test before tank mixing to ensure compatibility of Dual Magnum with other pesticides.
The following test assumes a spray volume of 25 gal/A. For other spray volumes, make appropriate changes in the ingredients.
Note: Nitrogen solutions or complete fluid fertilizers may replace all or part of the water in the spray. Because liquid ferti-
lizers vary, even within the same analysis, always check compatibility with pesticide(s) before use. Incompatibility of tank
mixtures is more common with suspensions of fertilizer and pesticides.
Test Procedure
1. Add 1.0 pt of carrier (fertilizer or water) to each of 2 one qt jars with tight lids. Note: Use the same source of water that
will be used for the tank mix and conduct the test at the temperature the tank mix will be applied.
2. To one of the jars, add 1/4 tsp or 1.2 milliliters of a compatibility agent approved for this use, such as Compex or Unite (1/4 tsp is equivalent to 2.0 pt/100 gal spray). Shake or stir gently to mix.
3. To both jars, add the appropriate amount of pesticide(s) in their relative proportions based on listed label rates. If more than one pesticide is used, add them separately with dry pesticides first, flowables next, and emulsifiable concentrates last. After each addition, shake or stir gently to thoroughly mix.
4. After adding all ingredients, put lids on and tighten, and invert each jar ten times to mix. Let the mixtures stand 15-30 minutes and then look for separation, large flakes, precipitates, gels, heavy oily film on the jar, or other signs of incom-patibility. Determine if the compatibility agent is needed in the spray mixture by comparing the two jars. If either mix-ture separates, but can be remixed readily, the mixture can be sprayed as long as good agitation is used. If the mixtures are incompatible, test the following methods of improving compatibility: (a) Slurry the dry pesticide(s) in water before addition, or (b) add 1/2 the compatibility agent to the fertilizer or water and the other 1/2 to the emulsifiable concentrate or flowable pesticide before addition to the mixture. If incompatibility is still observed, do not use the mixture.
5. After compatibility testing is complete, dispose of any pesticide wastes in accordance with the Storage and Disposal
section in this label.
CROP USE DIRECTIONS
CORN (ALL TYPES) – DUAL MAGNUM ALONE
Apply Dual Magnum, either preplant surface, preplant incorporated, preemergence, or lay-by, using the appropriate rate specified below.
PREPLANT SURFACE-APPLIED
Refer to instructions for use of Dual Magnum alone under Application Procedures.
Fall Application for Spring Weed Control:
• Apply after September 30 in ND, SD, MN, WI, and north of Route 30 in IA.
• Apply after October 15 north of Route 91 in NE and south of Route 30 in IA.
• Apply after October 31 north of Route 136 in IL.
In all locations, apply to crop stubble after harvest when the sustained soil temperature at a 4-inch depth is less than 55°F and falling. In minimum-till or no-tillage systems on soils having greater than 2.5% organic matter, use 1.67-2.0 pt/A on medium-textured and 2.0 pt/A on fine-textured soils. Do not apply to frozen ground. A tillage operation may precede the application. A fall and/or a spring tillage may follow application, but do not exceed an incorporation depth greater than 2-3 inches. Minimize furrow and ridge formation in the tillage operations. If a spring application is made, the total rate of the fall plus spring applications must not exceed the maximum total rate for corn, or illegal residues may result.
Fall Application for Italian Ryegrass Control: Dual Magnum may be applied for residual control of glyphosate-resistant
Italian ryegrass (Lolium multiflorum). Apply Dual Magnum at 1.33-1.67 pt/A in the fall (September 1–December 1) after
harvest of the previous crop and prior to Italian ryegrass emergence. Use the lower Dual Magnum rate for coarse-textured
soils and the higher rate for fine-textured soils. A tillage operation may precede the application. Do not incorporate to
a depth greater than 2-3 inches if tillage follows the application of Dual Magnum. For fall applications after emergence
of glyphosate-resistant Italian ryegrass, a Gramoxone brand can be tank mixed with Dual Magnum to control emerged
ryegrass. Refer to the Gramoxone brand label for specific rates, application instructions and restrictions. Other registered
herbicides may be tank mixed with Dual Magnum for control or improved control of other weeds present at the time of
application. Restrictions: (1) Do not apply Dual Magnum to frozen ground. (2) If a spring application is made, the combined
total amount of Dual Magnum applied in the fall plus the spring must not exceed the maximum seasonal S-metolachlor
rate for corn (3.9 pt/A depending on soil texture).
Fall Application for Control or Suppression of Yellow Nutsedge (ID, OR and WA only): For preemergent control or suppres-
sion of yellow nutsedge the following spring, apply 1.33 pt/A of Dual Magnum in the fall after the harvest of the previous
crop but before freeze-up. Fall applications of Dual Magnum can be surface-applied or incorporated. Restrictions: (1) Make
no more than one fall application per crop. (2) Apply not more than 1.33 pt/A in a single fall preplant application. (3) Do
not apply to frozen ground. (4) If a spring application is made, the combined total amount of Dual Magnum applied in the
fall plus the spring must not exceed the maximum seasonal S-metolachlor rate for corn (3.9 pt/A depending on soil texture).
Early Preplant Applications
A.
Use on medium- and fine-textured soils with minimum-tillage or no-tillage systems in CO, IA, IL, IN, KS, KY, MN, MO, MT, ND, NE, SD, TN, WI, and WY. Apply 2/3 the listed rate of Dual Magnum (1.67 pt/A on medium soils and 2.0 pt/A on fine soils) as a split treatment 30-45 days before planting and the remainder at planting. Applications made less than 30 days prior to planting may be as either a split or single treatment. Apply 1.33 pt/A on coarse soils not more than 2 weeks prior to planting. If a spring application is made, the total rate of the fall plus spring application must not exceed the maximum total rate for corn, or illegal residues may result.
On medium- and fine-textured soils with minimum- or no-tillage systems in CT, DE, MA, MD, ME, MI, NH, NY, OH, PA, RI, VA, VT, and WV, preplant surface applications may be applied following the directions for use above. If the amount of rainfall results in unsatisfactory length of weed control following the earlier treatment, a postemergence application of an appropriately labeled broadleaf and/or grass weed herbicide may be used, i.e., AAtrex, Beacon®, Bicep Magnum, Bicep II Magnum®, Exceed ®, Accent ®, Banvel, Basagran , bromoxynil (Brominal® or Buctril®), or 2,4-D. If the postemer-gence treatment includes the herbicide used preplant surface-applied, do not exceed the total labeled rate for corn on a given soil texture. Observe all directions for use, precautions, and limitations on the label of the postemergent herbicide.
PREPLANT INCORPORATED OR PREEMERGENCE
Follow instructions for use of Dual Magnum alone under Application Procedures. On coarse soils, apply 1.0-1.33 pt/A of
Dual Magnum if organic matter content is less than 3%, or 1.33 pt/A if organic matter content is 3% or greater. On medium
soils, apply 1.33-1.67 pt/A of Dual Magnum. On fine soils, apply 1.33-1.67 pt/A of Dual Magnum if organic matter content
is less than 3%, or 1.67-2.0 pt/A if organic matter content is 3% or greater.
POSTEMERGENCE OR LAY-BY
To extend the duration of weed control in corn, a maximum rate of 2.0 pt/A of Dual Magnum may be applied after corn
emergence until the corn plants reach 40 inches in height, following any preplant surface-applied, preplant incorporated,
or preemergence herbicide application, including Dual Magnum. For best results, make applications to soil free of emerged
weeds and directed toward the base of corn plants in excess of 5 inches tall. The total Dual Magnum rate applied on corn
during any one crop year must not exceed 3.9 pt/A, depending on soil texture.
Restrictions for all applications to corn: (1) do not graze or feed forage from treated areas for 30 days following applica-
tion and (2) Preharvest Interval (PHI): do not harvest sweet corn ears from treated areas for 30 days following application.
PROBLEM WEED CONTROL DIRECTIONS
Shattercane, Wild Proso Millet, Woolly Cupgrass, and Eclipta – Partial Control: For more consistent partial control of shatter-
cane, wild proso millet, woolly cupgrass, or eclipta, apply 1.0-1.33 pt/A of Dual Magnum preplant incorporated followed by
1.0-1.33 pt/A of Dual Magnum preemergence. Make the preemergence application during or after planting, but before weeds
and corn emerge. Apply the 1.33 pt/A rate of Dual Magnum when a heavy infestation of shattercane, wild proso millet, woolly
cupgrass, or eclipta is expected. A shallow cultivation may be needed to control any late emerging weeds.
Woolly Cupgrass and Wild Proso Millet Control Program: For control of these species, use the following 3-step program: (1)
Apply Dual Magnum early preplant, preplant incorporated, or preemergence at 1.67 pt/A on medium soils and 2.0 pt/A on
fine-textured soils, up to the maximum label rate. Lightly incorporate with a rotary hoe if rainfall does not occur within 5-7
days; (2) Apply a postemergence tank mix of Beacon at 0.38 oz/A or Exceed at 1 packet per 4 acres plus Accent SP at 0.33
oz/A plus 1.0 qt of crop oil concentrate plus 1.0 gal/A of 28% nitrogen, or the equivalent amount of ammonium sulfate,
when grasses are 2-3 inches tall and the corn is at least 4 inches tall; and (3) Cultivate 14-21 days after the postemergence
application.
Restrictions: (1) Do not apply more than the labeled application rate for a given soil texture per year, either as a single or
split treatment, or illegal residues may result. (2) In corn, Dual Magnum may be used up to 2.6 pt/A as either a preplant
surface, preplant incorporated, or preemergence treatment on soils having an organic matter content between 6% and
20%. (3) In the event of escape of annual weeds following a preplant surface, preplant incorporated, or preemergence
treatment of Dual Magnum, follow with a postemergence application of an appropriately labeled broadleaf and/or grass
weed herbicide, i.e., AAtrex, Beacon, Bicep II Magnum, Exceed, Accent, Banvel, Basagran, Brominal, Buctril, or 2,4-D. If the
post emergence treatment includes the herbicide used in the earlier treatment, do not exceed the total labeled rate for
corn on a given soil texture. (4) Brominal or Buctril may be applied postemergence alone or in tank mix combination with
AAtrex. Do not exceed 1.2 lb ai/A of AAtrex in tank mix combination with Brominal or Buctril postemergence. Refer to the
AAtrex, Brominal, and Buctril labels for specific rates and precautions. (5) Do not use Dual Magnum on peat or muck soils.
CORN – DUAL MAGNUM COMBINATIONS
Dual Magnum in any tank mixture for corn may be applied in water or fluid fertilizer before corn emerges. Use only water as a carrier when Dual Magnum is applied after corn emergence.
Restrictions: For all applications to corn, (1) do not graze or feed forage from treated areas for 30 days following applica-
tion and (2) Preharvest Interval (PHI): do not harvest sweet corn ears from treated areas for 30 days following application.
IMPORTANT: FOR TANK MIXTURES WITH AATREX (OR OTHER BRANDS OF ATRAZINE) – If applying Dual Magnum in tank
mixture with AAtrex, all the restrictions and rate limitations on the AAtrex label must be followed if more restrictive/
protective than those on this label. In addition, if AAtrex is/must be applied at rates lower than those listed on this label,
broadleaf weed control may be affected. Refer to the AAtrex label for weeds controlled at the reduced rates.

application instructions for Dual Magnum alone on corn. Apply Dual Magnum + AAtrex or Princep, or Dual Magnum +
AAtrex + Princep on medium soils (1.67 pt/A of Dual Magnum + 3.2-4.0 pt/A of AAtrex 4L or Princep 4L, or AAtrex 4L +
Princep 4L combined) and on fine soils (1.67-2.0 pt/A of Dual Magnum + 4.0 pt/A of AAtrex 4L or 4.0-5.0 pt/A of Princep 4L,
or AAtrex 4L + Princep 4L combined) in minimum-tillage and no-tillage systems in CO, IA, IL, IN, KS, KY, MN, MO, MT, ND,
NE, SD, TN, WI, and WY. Apply the tank mixtures as a split or single treatment in those states and as indicated in the Dual
Magnum Alone – Preplant Surface-Applied section of the label for corn. On coarse soils, apply 1.33 pt/A of Dual Magnum
and 3.2 pt/A of AAtrex 4L or Princep 4L, or AAtrex 4L + Princep 4L combined.
Preplant Incorporated or Preemergence: Follow instructions for use of Dual Magnum alone under Application Procedures.
Apply Dual Magnum + AAtrex or Princep, or Dual Magnum + AAtrex + Princep, using the appropriate rates from Table 3.
Restriction: Do not apply more than the labeled rate for a given soil texture per year, either as a split or single treatment.
Shattercane and Wild Proso Millet – Partial Control
For more consistent partial control of shattercane or wild proso millet, where Dual Magnum is applied in tank mixture or
sequentially with other registered corn herbicides, the following applications may be made:
Apply 1.0-1.33 pt/A of Dual Magnum + 2.0 lb ai/A of AAtrex or Princep preplant incorporated, followed by 1.0-1.33 pt/A of Dual Magnum preemergence. Make the preemergence application during or after planting, but before weeds and corn emerge.
Apply Dual Magnum at 1.33 pt/A alone or in tank mix combination with up to 2.0 lb ai/A of AAtrex or Princep preplant incorporated. Do not exceed the total rate of triazine herbicide listed in combination with Dual Magnum for corn grown on a given soil texture. Follow with a post-directed application of Evik® 80W at the labeled rate. Refer to the Evik 80W label for specific directions for the post-directed application.
Apply Eradicane® (or equivalent EPTC or butylate formulations) at labeled rates preplant incorporated, followed by a preemergence application of Dual Magnum at 1.0-1.33 pt/A. Do not use Eradicane on soils where rapid degradation has been shown to occur. Make the preemergence application during or after planting, but before weeds and corn emerge.
Precaution: When following the application regimes in numbers 1-3 above, a shallow cultivation may be needed after the
preemergence or postemergence application to help control any late emerging shattercane or wild proso millet plants.
Restriction: Do not exceed a total of 1.9 lb ai/A (2.0 pt of Dual Magnum) in the preplant incorporated plus preemergence
application on soils with less than 6% organic matter, or crop injury may occur.

** When using the tank mixture of Dual Magnum + AAtrex Nine-O + Princep Caliber 90, use equal rates of each as shown
when heavy broadleaf weed infestations are expected. When heavy infestations of crabgrass or fall panicum are expected, use a 1:2 ratio of AAtrex + Princep instead of the 1:1 ratio given in Table 3. (Example: Total AAtrex Nine-O + Princep Caliber 90 = 1.2 lb/A, use 0.4 lb of AAtrex + 0.8 lb of Princep, respectively.) Refer to Comment No. 2 following Table 2 for AAtrex 4L and Princep 4L conversions.
*** For cocklebur, yellow nutsedge, and velvetleaf control on fine-textured soils above 3% organic matter, apply 2.25 lb/A
of AAtrex Nine-O, or equivalent rates of AAtrex 4L, or the same total amount of AAtrex + Princep with 1.33-1.67 pt/A of Dual Magnum.
TANK MIXTURE WITH AATREX – POSTEMERGENCE
Weeds Partially Controlled
Apply 1.0 pt/A of Dual Magnum + 1.3 lb/A of AAtrex Nine-O* on coarse soils, 1.33 pt/A of Dual Magnum + 1.8 lb/A of AAtrex
Nine-O on medium soils, or 1.33-1.67 pt/A of Dual Magnum + 1.8-2.2 lb/A** of AAtrex Nine-O on fine soils. Apply this tank
mixture before grass and broadleaf weeds pass the 2-leaf stage and before corn exceeds 5 inches in height. Application to
weeds larger than the 2-leaf stage will generally result in unsatisfactory control.
Lay-by: Apply to corn plants not more than 12 inches tall. Make applications to corn in excess of 5 inches directed to the
base of the corn plants; whereas, applications to corn plants less than 5 inches tall may be made over the top. Occasionally,
some corn leaf burn may result, but this will likely not affect later growth or yield. Do not apply this postemergence tank
mixture in fluid fertilizer, or severe crop injury may occur.
*When using AAtrex 4L, use equivalent rates. One lb of AAtrex Nine-O = 1.8 pt of AAtrex 4L.
** For better control of cocklebur, morningglory, velvetleaf, and yellow nutsedge on fine-textured soils above 3% organic
matter, apply 2.2 lb/A of AAtrex Nine-O, or equivalent rate of AAtrex 4L, with 1.33-1.67 pt/A of Dual Magnum.
Tank mixtures of Dual Magnum + AAtrex may be applied following use of any registered preplant surface-applied, preplant incorporated, or preemergence corn herbicide, including Dual Magnum + AAtrex.
Restriction: The total Dual Magnum rate must not exceed 3.9 pt, nor the AAtrex rate more than 2.5 lb ai/A during any one

TANK MIXTURE WITH BANVEL
Preemergence: Use this tank mixture only on field corn which is flat-planted (no furrows) in CO, IA, IL, IN, KS, MN, NE, OH,
SD, and WI.
In addition to the weeds controlled by Dual Magnum alone, Dual Magnum + Banvel, applied preemergence, also controls
lambsquarters, ragweed, smartweed, cocklebur*, jimsonweed*, morningglory*, and velvetleaf*.
*Partially controlled.
Apply Dual Magnum + Banvel preemergence. Broadcast the labeled rate of Banvel with 1.33 pt/A of Dual Magnum on medium soils, or with 1.33-1.67 pt/A of Dual Magnum on fine soils. Do not apply on coarse soils or on soils with less than 2.5% organic matter. Apply this tank mixture to the soil surface at planting or after planting, but before corn emerges. Plant corn at least 1.5 inches deep and apply behind planting equipment, avoiding incorporation by the planter wheel or other seed covering device. Do not incorporate before corn emergence. If it is necessary to rotary hoe to break the soil crust, do not disturb the soil more than 1/2 inch deep.
Postemergence for Control of Pigweed (Mid-Atlantic states, including DE, MD, PA, VA, and WV): Apply 1.0-1.5 pt of Dual
Magnum + 0.5-1.0 pt/A of Banvel or Clarity® by ground equipment when pigweed plants are less than 3 inches tall and
before corn exceeds 5 inches in height in a minimum of 20 gal of spray per acre. Use the lower rate on coarse-textured and
low organic matter soils. Use the higher rate on fine-textured and high organic matter soils.
Precaution: Avoid drift to sensitive nontarget plants, such as soybeans, during application, or injury may occur.
Restriction: Do not apply with aircraft.
TANK MIXTURE WITH AATREX OR PRINCEP + PROWL FOR PROLONGED CONTROL OF LAMBSQUARTERS AND
PIGWEED IN FIELD CORN ONLY (NORTHEAST U.S., INCLUDING MI, IN, KY, AND STATES EAST OF THESE)
For prolonged control of lambsquarters and pigweed, in addition to a broad spectrum of annual broadleaf and grass
weeds, Dual Magnum in tank mix combination with AAtrex* or Princep + Prowl 4E may be applied after planting, but
before corn or weeds emerge. Apply by ground equipment in a minimum of 10 gal of water or 20 gal of liquid fertilizer.

TANK MIXTURE OF DUAL MAGNUM WITH AATREX OR PRINCEP, OR AATREX + PRINCEP WITH GRAMOXONE
BRANDS, LANDMASTER BW, TOUCHDOWN OR ROUNDUP FOR MINIMUM-TILLAGE OR NO-TILLAGE SYSTEMS
In minimum-tillage or no-tillage systems where corn is planted directly into a cover crop, stale seedbed, established sod,
or previous crop residues, tank mix the contact herbicides Gramoxone brands, Landmaster BW, Touchdown brands or
Roundup brands with Dual Magnum + AAtrex, Dual Magnum + Princep, or Dual Magnum + AAtrex + Princep. See Comment
No. 7 following Table 2. The Dual Magnum, Dual Magnum + AAtrex or Princep, or Dual Magnum + AAtrex + Princep
portion of the tank mixture provides preemergence control of the weeds listed on this label in the tank mixture section
for Dual Magnum, Dual Magnum + AAtrex or Princep, or Dual Magnum + AAtrex + Princep – Preplant Surface, Preplant
Incorporated, or Preemergence.
Application: Apply before, during, or after planting, but before the corn emerges. Add Gramoxone brands, Landmaster BW,
Touchdown brands or Roundup brands and apply as directed on the product label.
Gramoxone Brands: Apply as directed on the product label. This treatment will not control weeds taller than 6 inches.
Precaution: Do not apply combinations containing Gramoxone brands in suspension-type liquid fertilizers, because the
activity of paraquat will be reduced.
Landmaster BW: See the Landmaster BW label for weeds controlled, listed rates for specific weeds, and other information
concerning use.
Touchdown Brands or Roundup Brands: See the Touchdown brand or Roundup brand labels for weeds controlled, listed
rates, and other use directions.
Apply in 20-60 gal of water or fluid fertilizer per acre with ground equipment.
On coarse soils, apply 1.0 pt/A of Dual Magnum with 1.3 lb of AAtrex Nine-O* or Princep Caliber 90*, or with 0.7 lb of
AAtrex Nine-O** + 0.7 lb of Princep Caliber 90**. On medium soils, apply 1.33 pt/A of Dual Magnum with 1.8 lb of AAtrex
Nine-O or Princep Caliber 90, or with 0.9 lb of AAtrex Nine-O + 0.9 lb of Princep Caliber 90. On fine soils***, apply 1.33-
1.67 pt/A of Dual Magnum with 1.8-2.2 lb of AAtrex Nine-O or Princep Caliber 90, or with 0.9-1.1 lb of AAtrex Nine-O +
0.9-1.1 lb of Princep Caliber 90.
*Use Princep in preference to AAtrex when heavy infestations of crabgrass or fall panicum are expected.
** When using the tank mixture of Dual Magnum + AAtrex Nine-O + Princep Caliber 90, use equal rates of AAtrex and
Princep as shown when heavy broadleaf weed infestations are expected. When heavy infestations of crabgrass or fall panicum are expected, use a 1: 2 ratio of AAtrex + Princep instead of the 1:1 ratio given. (Example: Total AAtrex Nine-O + Princep Caliber 90 = 1.8 lb/A, use 0.6 lb of AAtrex + 1.2 lb of Princep, respectively.) Refer to Comment No. 2 following Table 2 for AAtrex 4L and Princep 4L conversions.
*** For cocklebur, yellow nutsedge, and velvetleaf control on fine-textured soils above 3% organic matter, apply 2.25 lb/A
of AAtrex Nine-O, or equivalent rate of AAtrex 4L, or the same total amount of AAtrex + Princep, with 1.33-1.67 pt/A of Dual Magnum.
TANK MIXTURE WITH AATREX; OR AATREX + 2,4-D; OR AATREX + 2,4-D + BANVEL FOR MINIMUM-TILLAGE
OR NO-TILLAGE SYSTEMS
In minimum-tillage or no-tillage systems where corn is planted directly into a cover crop, stale seedbed, established sod, or
previous crop residues, Dual Magnum applied in combination with AAtrex will kill most emerged small annual weeds. Apply
Dual Magnum + AAtrex before, during, or after planting, but before corn emerges, according to the rates in Table 3.
Where heavy crop residues exist, add 0.8-1.6 pt/A of an appropriately labeled 3.8 lb ai/gal of 2,4-D amine (such as Weedar 64, Weedar 64A, DMA-4 Herbicide, Weedone® 638, or Formula 40) to the spray tank last and apply in a minimum of 25 gal of carrier per acre.
As carriers, nitrogen solutions and complete liquid fertilizers applied before corn emergence enhance burndown of exist-ing weeds. Therefore, for best results use nitrogen solutions or complete liquid fertilizers as carriers instead of water. Add X-77 surfactant at 1.0-2.0 qt/100 gal of diluted spray, or another appropriate surfactant at its labeled rate, or add crop oil concentrate plus 28% liquid nitrogen (or equivalent). Apply before weeds exceed 3 inches in height. If alfalfa is present, add Banvel to the spray mixture at 0.33-0.5 pt/A and apply before alfalfa exceeds 6 inches in height.
For fields with existing sod grasses (e.g., bromegrass, orchardgrass, rye, or timothy), when existing weeds exceed 3 inches in height or when very dry conditions exist, add Gramoxone brands at the rate indicated on the product label in place of or in addition to 2,4-D as indicated above. Do not apply Gramoxone brands in suspension-type liquid fertilizer. Observe all directions for use, precautions, and restrictions on the respective product labels when applying these products in tank mix combination. Use Balance combinations only on field corn.
TANK MIXTURE WITH MARKSMAN IN CONSERVATION TILLAGE – FIELD AND SILAGE CORN
In conservation tillage systems where corn is planted directly into a cover crop or previous crop residue, Dual Magnum +
Marksman will kill most emerged small annual weeds. Apply Dual Magnum + Marksman before, during, or after plant-
ing, but before corn emergence on medium and fine soils with greater than 2.5% organic matter. For fields with existing
vegetation exceeding 3 inches in height or when very dry conditions exist, add Gramoxone brands at its standard rate.
Dual Magnum + Marksman may be applied postemergence to corn less than 3 inches tall and before weedy grasses exceed
the 2-leaf stage.
As carriers, nitrogen solutions and complete liquid fertilizers applied before corn emergence enhance burndown of existing weeds. Do not apply Gramoxone brands in suspension-type liquid fertilizer or use on emerged corn.
Refer to the Marksman label and follow all directions, limitations, precautions, and restrictions regarding application and use in corn.
TANK MIXTURE WITH BALANCE PRO – FIELD CORN ONLY
Dual Magnum and Balance PRO have a complementary crop response and weed control profile which allows various tank
mix rate combinations to be considered. The addition of Balance PRO will improve the control of certain problem weeds
including Texas panicum, woolly cupgrass, and wild proso millet. Dual Magnum improves both the duration and spectrum
of annual grass and small seeded broadleaf weed control, in particular foxtails (yellow foxtail), witchgrass, and yellow
nutsedge.
To reduce the risk of an adverse crop response, the Balance PRO label does not allow applications to coarse-textured soils with less than 1.5% organic matter and warns about applications to all soils with less than 1.5% organic matter or with pH greater than 7.5, as well as applications made to areas in fields with clay knolls, eroded hillsides, and exposed subsoil.
Listed below are compensating rate options for combinations of Dual Magnum and Balance PRO, i.e. higher rates of Dual Magnum are combined with lower rates of Balance PRO, and vice versa. Select a rate option for Dual Magnum plus Balance PRO by weighing the intensity of problem weed pressure (population presence and density) and your acceptance for risk of an adverse crop response. For example, where Texas panicum, woolly cupgrass, or wild proso millet are a primary target weed, use a tank mix combination with a higher Balance PRO rate for the given soil type.
Where your acceptance of an adverse crop response risk is low and/or a more general weed spectrum is targeted (especially yellow foxtail, witchgrass or yellow nutsedge), use a tank mix combination with a higher Dual Magnum rate for the given soil type. Where a target weed is listed as controlled on both product labels, a tank mix combination option including intermediate rates of both products may be used. Where a target weed is listed as controlled on only one product label, do not apply a rate of that product below what is listed for that weed on the individual product label, or unacceptable control may result. Follow all other directions for use, rate limitations, precautions and restrictions on both the Dual Magnum and Balance PRO product labels.
Dual Magnum plus Balance PRO tank mix rate options when applied preplant (incorporated or surface applied) up to 7 days before planting or preemergence in field corn: For coarse-textured soils, where 1.5 or 1.88 oz/A of Balance PRO is used, 1.0-1.33 pt/A of Dual Magnum may be applied.
Do not use Balance PRO on coarse-textured soils with less than 1.5% organic matter.
For medium-textured soils, where 1.5 oz/A of Balance PRO is used, rates as low as 1.33 pt/A of Dual Magnum may be
applied. Where 1.88 or 2.25 oz/A of Balance PRO is used, rates as low as 1.0 pt/A of Dual Magnum may be applied. Dual
Magnum can be used in combinations with Balance PRO at rates up to 1.67 pt/A on medium-textured soils.
For fine-textured soils, where 1.5 oz/A of Balance PRO is used, rates as low as 1.33 pt/A of Dual Magnum may be applied
if the soil organic matter is less than 3% - if the soil organic matter content is 3% or greater, 1.67 pt/A of Dual Magnum
may be applied. Where 1.88 or 2.25 oz/A of Balance PRO is used, rates as low as 1.33 pt/A of Dual Magnum may be applied.
Where 3.0 oz/A or more of Balance PRO are used, rates as low as 1.0 pt/A of Dual Magnum may be applied. Dual Magnum
can be used in combinations with Balance PRO at rates up to 2.0 pt/A on fine-textured soils if the soil organic matter con-
tent is 3% or greater.
TANK MIXTURES FOR POSTEMERGENCE SALVAGE WEED CONTROL IN FIELD CORN ONLY
For postemergence control of weeds in specific types of field corn, the Dual Magnum combinations listed below may be
used. Full season weed control from early preplant, preplant incorporated, or preemergence treatments can lead to maxi-
mum yield potential under competition-free conditions. However, if control of emerged weeds is needed, a postemergence
program listed below can be applied to provide residual control for the remainder of the season.
Restrictions: (1) Follow all label directions, instructions, precautions, and restrictions for each product used. (2) Do not use
fluid fertilizer with these mixtures or corn injury may occur. (3) For each tank mixture with Dual Magnum, apply only to the
specific field corn type specified on the tank mix product label. (4) In-row weed control may be reduced because of lack of
coverage when applied to corn over 4 inches tall.

or Corn Warranted by Bayer CropScience as Being Tolerant to Liberty Herbicide or Ignite 280 SL Herbicide
These tank mixtures can be applied postemergence to weeds and corn from seed designated as LibertyLink or corn
warranted by Bayer CropScience as being tolerant to Liberty Herbicide or Ignite 280 SL Herbicide. Liberty provides post-
emergence control of a broad spectrum of grass and broadleaf weeds and Dual Magnum provides residual control of
grasses and certain broadleaf weeds listed in the label section Dual Magnum Applied Alone – Weeds Controlled. Refer to
the Dual Magnum Alone – Preplant Incorporated or Preemergence section and use the minimum rate per soil texture and
organic matter classification for season-long residual control from this tank mix combination with Liberty. Refer to the
Liberty Herbicide or Ignite 280 SL Herbicide labels for the postemergence application rates according to weed species and
their maximum height at the time of postemergence application. Where multiple weed species are present, use the highest
Liberty rate listed to control the species and growth stages present.
Follow all applicable use directions, limitations, precautions, and restrictions regarding application to corn on the Dual Magnum, Liberty Herbicide, and Ignite 280 SL Herbicide labels. Where difficult species and/or severe weed populations are expected, use the maximum rate where rate ranges are listed.

Tolerant Corn (e.g., Roundup Ready® or Agrisure™ GT)
The tank mixture of Dual Magnum + Touchdown or Roundup brands can be applied postemergence to weeds and to corn
designated as glyphosate-tolerant. Application may be applied postemergence to glyphosate-tolerant corn from emer-
gence until corn reaches 30 inches tall or the V8 stage (8 leaves with collars), whichever comes first. This mixture will provide
postemergence control of weed species on the Touchdown brand or Roundup brand label and residual control of weed
species on the Dual Magnum label. Use the minimum Dual Magnum rate postemergence with Touchdown or Roundup in
glyphosate-tolerant corn as specified in the Corn – Dual Magnum Alone – Preplant Incorporated or Preemergence section
of this label according to soil texture and organic matter. Refer to the Touchdown brand or Roundup brand label and
follow appropriate use directions, application procedures, precautions, and restrictions. Refer to the Touchdown brand or

on medium soils, or 1.0-1.33 pt/A on fine soils. Apply Dual Magnum preplant incorporated or preemergence in Area 2** at
1.0 pt/A on sandy loams, 1.0-1.33 pt/A on medium soils, or 1.33 pt/A on fine soils. Apply Dual Magnum postemergence to
cotton and preemergence to weeds at 0.5-1.33 pt/A, according to the state rate limitations in the following Postemergence
section. Do not use on sands and loamy sand.
*Area 1 = AR, KS, LA, MS, TN, and Bootheel of MO
**Area 2 = NM, OK, and TX
Fall Application for Italian Ryegrass Control: Dual Magnum may be applied for residual control of glyphosate-resistant
Italian ryegrass (Lolium multiflorum). Apply Dual Magnum at 1.33-1.67 pt/A in the fall (September 1 – December 1) after
harvest of the previous crop and prior to Italian ryegrass emergence. Use the lower Dual Magnum rate for coarse-textured
soils and the higher rate for fine-textured soils. A tillage operation may precede the application. Do not incorporate to
a depth greater than 2-3 inches if tillage follows the application of Dual Magnum. For fall applications after emergence
of glyphosate-resistant Italian ryegrass, Gramoxone brands can be tank mixed with Dual Magnum to control emerged
ryegrass. Refer to the Gramoxone brands label for specific rates, application instructions and restrictions. Other registered
herbicides may be tank mixed with Dual Magnum for control or improved control of other weeds present at the time of
application. Restrictions: (1) Do not apply Dual Magnum to frozen ground. (2) If a spring application is made, the combined
total amount of Dual Magnum applied in the fall plus the spring must not exceed the maximum seasonal S-metolachlor
rate for cotton (2.6 pt/A, depending on soil texture).
Preplant Incorporated (NM, OK, and TX Only): Apply to the soil and incorporate into the top inch of soil immediately before
planting, at planting, or after planting, but before crop or weeds emerge. Use a rolling cultivator or similar implement to
uniformly incorporate not more than 1 inch deep. Use a preplant incorporated application if furrow irrigation is used or
when a period of dry weather after application is expected. Where furrow irrigation is used, wet the top of the bed for
best results. If the crop is to be planted on beds, apply and incorporate after bed formation. Plant cotton below the zone of
incorporation; i.e., at least 1 inch on fine soils and 1.5 inches on coarse and medium soils. If incorporated prior to planting,
use a planter that will result in a minimum of soil disturbance.
Note: For best control of yellow nutsedge and suppression of seedling johnsongrass, apply Dual Magnum preplant incorpo-
rated at the maximum rate for the soil texture, whether applied alone or mixed with Caparol 4L.
Preemergence: Apply to the soil surface at planting or after planting, but before weeds or crop emerge.
Postemergence: Apply Dual Magnum broadcast over-the-top or directed to the soil surface according to the rate restrictions
listed below by state. Over-the-top postemergence application may be made not later than 100 days before harvest, and
directed-postemergence application may be made not later than 80 days before harvest. Application before weeds emerge
or after clean cultivation to remove existing weeds is necessary since Dual Magnum will not control emerged weeds. Dual
Magnum post emergence may be applied over any previous registered herbicide treatment. In sprinkler-irrigated areas,
sprinkler irrigate after application with 1/2-1 inch of water (1/2 inch on coarse-textured soils to 1 inch on fine-textured soils)
to incorporate Dual Magnum. In furrow-irrigated areas, apply Dual Magnum, incorporate with a rolling cultivator or similar
implement that provides uniform shallow incorporation (2 inches or less), and then irrigate. In nonirrigated areas, if at least
1/2 inch of rainfall does not occur within 10 days after application, cultivate with a rolling cultivator or similar implement
that provides uniform shallow incorporation of Dual Magnum.
VA, NC, SC, GA, FL, and AL: Apply Dual Magnum postemergence at 1.0-1.33 pt/A.
TN, AR, KS, MS, MO, and LA: Apply Dual Magnum postemergence at 0.5-1.33 pt/A.
TX, OK, NM, AZ, CA, and Clay Soils in AR: Apply Dual Magnum postemergence at 1.0-1.33 pt/A before August 1.
Multiple Applications: Where weed pressure is heavy, difficult to control species are expected, or reinfestation may occur,
and a weed control program is used, multiple applications of Dual Magnum are effective when used as part of the weed
control program. Apply as a preplant incorporated or preemergence treatment and follow with an application postemer-
gence to cotton before weeds emerge or after clean cultivation to remove existing weeds, since Dual Magnum will not
control emerged weeds. Apply Dual Magnum postemergence over a previous preplant or preemergence Dual Magnum
application as shown in the following table.
Multiple Dual Magnum Applications to Cotton
Preplant Incorporated or
MS, LA, TN, AR, KS, MO 0.5-1.33 (Preemergence Only) 1.0-1.33 before August 1 1.0-1.33 (Preemergence Only) In sprinkler-irrigated areas, sprinkler irrigate after application with 1/2-1 inch of water (1/2 inch on coarse-textured soils to1 inch on fine-textured soils) to incorporate Dual Magnum. In furrow-irrigated areas, apply Dual Magnum, incorporate with a rolling cultivator or similar implement that provides uniform shallow incorporation (2 inches or less), and then irrigate. In nonirrigated areas, if at least 1/2 inch of rainfall does not occur within 10 days after application, cultivate with a rolling cultivator or similar implement that provides uniform shallow incorporation of Dual Magnum.
Precautions: (1) For best control of yellow nutsedge and suppression of seedling johnsongrass, apply Dual Magnum pre-
plant incorporated, preemergence, or postemergence to cotton and preemergence to weeds at the maximum rate for the
soil texture, whether applied alone or in combinations. (2) To avoid concentration in the seed furrow, do not make broad-
cast applications of Dual Magnum to cotton planted in furrows more than 2 inches deep. When making band applications
to cotton planted in furrows deeper than 2 inches, ensure that band width does not exceed the width of the bottom of
the furrow.
Restrictions: (1) Do not apply more than a total of 2.0 pt/A on coarse soils or 2.6 pt/A of Dual Magnum on medium and fine
soils during a growing season. These treatments may be applied over previous registered herbicide treatments. (2) Do not
apply Dual Magnum on sand or loamy sand soils, or in areas where water is likely to "pond" over the bed. (3) In furrow-
planted cotton, to avoid concentration in the furrow and potential injury, do not apply Dual Magnum postemergence until
after first "knifing" or cultivation to level soil surface. (4) Do not apply over-the-top in fluid fertilizer or any other adjuvant,
surfactant, oil, or other pesticide not listed in the cotton section of this label, or injury may occur. (5) Do not apply on
Taloka silt loam. (6) Do not use in Gaines County, TX. (7) Do not graze or feed forage or fodder from cotton to livestock.
COTTON – DUAL MAGNUM COMBINATIONS
TANK MIXTURE WITH CAPAROL 4L
Dual Magnum tank mixtures with Caparol 4L may be applied preplant incorporated or preemergence in water or fluid
fertilizer. When fluid fertilizer is used as a carrier for Dual Magnum, either alone or in combination with Caparol 4L, mix
only the amount that will be sprayed in one operation. Do not allow these mixtures to stand without agitation. Only water
may be used as a carrier for postemergence-directed application.
In addition to those weeds controlled by Dual Magnum alone, Dual Magnum + Caparol 4L, applied preplant incorporated or preemergence, also controls the following weeds: junglerice, wild oats, annual morningglory, groundcherry, hairy night-shade, lambsquarters, malva, mustard, prickly sida (teaweed), purslane, ragweed, and shallow-germinating seedlings of cocklebur and coffeeweed. As a postemergence-directed application, Caparol provides postemergence control and residual control of weeds on its label, while Dual Magnum provides residual control of weed species on its label. Dual Magnum will not control emerged weeds.
Preplant Incorporated or Preemergence: Apply Dual Magnum + Caparol 4L, either preplant incorporated or preemergence,
using the appropriate rate from Table 5. Plant cotton below the zone of incorporation; i.e., at least 1.0 inch on fine soils
and 1.5 inches on coarse and medium soils. If incorporated before planting, use a planter that will result in a minimum of
soil disturbance.

Refer to the Caparol 4L label for further instructions and restrictions.
TANK MIXTURE WITH COTORAN DF
Dual Magnum may be applied in tank mixture with Cotoran DF preemergence for control of those weeds controlled by
Dual Magnum alone and those as listed on the Cotoran DF label. This combination will also control spotted spurge, hyssop
spurge, nodding spurge, and prostrate spurge. Apply to the soil surface at planting or after planting, but before weeds or
crop emerge, using the appropriate rates from Table 6. The tank mixture may be applied postemergence to cotton, but
preemergence to weeds, or it may be applied postemergence to both cotton and broadleaf weeds for control of weeds on
the Cotoran label. Apply as a directed, semi-directed, or over-the-top spray. Dual Magnum will not control emerged weeds,
but will provide preemergence control of species on its label.
Mixing Instructions: Incompatibility may occur when tank mixing Dual Magnum and Cotoran DF. To help overcome this
condition, fill the spray tank 1/4 full with water or fluid fertilizer and start agitation, add the Cotoran DF and allow it to
become dispersed. Add X-77 at 0.5% volume/volume final spray (4.0 pt/100 gal), then add the Dual Magnum and finally
the rest of the water or fluid fertilizer. Agitate during mixing and application to maintain a uniform suspension. Do not
use fluid fertilizer as a carrier for postemergence applications.

Postemergence: This tank mixture may be applied postemergence to cotton, but preemergence to weeds or post emergence
to both cotton and weeds for control of weeds on the Cotoran label. Apply as a directed, semi-directed, or over-the-top
spray. Dual Magnum will not control emerged weeds, but will provide preemergence control of species on its label. Where
rate ranges are given for Cotoran DF, use the higher rate when applying postemergence to weeds that are 2 inches or less.
These treatments may be applied over previous registered treatments, including Dual Magnum, provided the maximum
label rate of any product is not exceeded.
To avoid concentration in the seed furrow, do not make broadcast applications of Dual Magnum + Cotoran to cotton planted in furrows more than 2 inches deep. Band applications may be made to cotton planted in furrows deeper than 2 inches, but band width must not exceed the width of the bottom of the furrow.
Restrictions: (1) Do not apply Dual Magnum + Cotoran on sand or loamy sand soils, or in areas where water is likely to
"pond" over the bed, or crop injury may occur. (2) The use of Cotoran following the use of a systemic insecticide at planting
may result in crop injury. (3) Do not use on Taloka silt loam. (4) Do not use in Gaines County, TX. (5) Do not feed treated
forage or gin trash to livestock, or graze treated areas.
Refer to the Cotoran labels for further instructions, precautions, and restrictions.

TOUCHDOWN BRANDS OR ROUNDUP BRANDS FOR MINIMUM-TILLAGE OR NO-TILLAGE SYSTEMS
In minimum-tillage or no-tillage systems where cotton is planted directly into a cover crop, stale seedbed, or previous crop
residues, the contact herbicides Gramoxone brands, Touchdown brands or Roundup brands may be added to a tank mix
of either Dual Magnum or Dual Magnum + Cotoran. When used as directed, the Gramoxone brands portion of the tank
mixture controls most emerged weeds and suppresses many perennial weeds. Touchdown or Roundup brand combinations
will control emerged annual and perennial weeds when applied as directed on the Touchdown or Roundup label. The Dual
Magnum and Dual Magnum + Cotoran portion of the tank mixture provides preemergence control of the weeds listed on
this label in the Dual Magnum and Dual Magnum + Cotoran sections, respectively.
Refer to the label of each product used in combination and observe the planting details, information regarding applica-
tion, geographical restrictions, and all other precautions and restrictions. Refer to Mixing Instructions under Tank Mixture
with Cotoran DF section.
Application: Apply before, during, or after planting, but before the cotton emerges. Apply Dual Magnum at 0.8-1.0 pt/A
on sandy loams, medium-, and fine-textured soils. Refer to Table 6 for the Cotoran DF rates.
Gramoxone Brands: Apply as directed on the product label. This treatment will not control weeds taller than 6 inches.
Note: Do not apply combinations containing Gramoxone brands in suspension-type liquid fertilizers, as the activity of
paraquat will be reduced.
Touchdown Brands or Roundup Brands: See the Touchdown or Roundup label for weeds controlled, listed rates, and other
use directions.
Precaution: Do not apply Dual Magnum + Cotoran 4L + Roundup in tank mixture because of compatibility problems.
Apply in 20-60 gal of water or fluid fertilizer per acre with ground equipment.
Precautions: (1) If heavy rain occurs soon after application, crop injury may result, especially in poorly drained areas where
water stands for several days, or where the seeding slit has not been properly closed. (2) Refer to the Cotoran labels and
the Tank Mixture with Cotoran DF section of this label for further instructions, precautions, and restrictions.
Restriction: Do not use in Gaines County, TX.

fied on their respective labels. (3) Do not use on sand or loamy sand soils in Gaines County, TX.
SOYBEAN, IMMATURE SEED
Dual Magnum may be applied preplant or preemergence for the control or suppression of grass and small seeded broadleaf weeds in immature-seed soybean or other food-grade soybeans. For specific rates, see the rate table listed below.
Preplant Surface-Applied: For minimum-tillage or no-tillage systems only, Dual Magnum alone may be applied up to 45 days
before planting. Use only split applications for treatments made 30-45 days before planting, with 2/3 the listed broadcast
rate for the crop and soil texture applied initially and the remaining 1/3 applied at planting. Treatments less than 30 days
before planting may be made either as a split or a single application. If weeds are present at the time of treatment, apply in
a tank mixture combination with a contact herbicide (for example, Gramoxone brands, Touchdown, or Roundup). Observe
directions for use, precautions, and restrictions on the label of the contact herbicide. To the extent possible, do not move
treated soil out of the row or move untreated soil to the surface during planting, or weed control will be diminished.
Preplant Incorporated: Apply Dual Magnum to the soil and incorporate into the top 2 inches of soil within 14 days before
planting, using a finishing disk, harrow, rolling cultivator, or similar implement capable of providing uniform 2-inch
incorporation. Use a preplant incorporated application if furrow irrigation is used or when a period of dry weather after
application is expected. If crop will be planted on beds, apply and incorporate Dual Magnum after bed formation, unless
specified otherwise.
Preemergence: Apply Dual Magnum during planting (behind the planter) or after planting, but before weeds emerge.

GRASSES GROWN FOR SEED (ID, OR, WA) – DUAL MAGNUM APPLIED ALONE
To control weeds and volunteer grasses in established grasses grown for seed, apply Dual Magnum to established stands of
tall fescue, orchardgrass, perennial ryegrass, fine fescue, bentgrass, and Kentucky bluegrass just before, during, or imme-
diately following the first fall rains or just before or during a late summer or early fall irrigation, but before target grasses
emerge. The seed crop must have had one seed harvest or been established at least one year. Evenly spread, remove, or
burn the post-harvest residue (straw) before applying Dual Magnum. Rainfall or irrigation is required after application and
before weed emergence for best control. Dual Magnum will provide preemergence control/suppression of volunteer seed-
lings of perennial ryegrass, fine fescue spp., tall fescue, orchardgrass, bentgrass and Kentucky bluegrass. Dual Magnum will
control those weed species listed in the Dual Magnum Alone section of the Dual Magnum label and will suppress or control
rattail fescue, annual bluegrass, Italian ryegrass, California brome, downy brome, and roughstalk bluegrass.
Apply Dual Magnum by ground equipment in a minimum of 10 gallons of water per acre using the rate listed below according to grass species.
Established Grass Crop Grown for Seed
Fine fescue spp.
Perennial ryegrass Kentucky bluegrass Precautions: (1) Avoid application after the 15th of November or poor control may result. (2) Tank mixtures with other
pesticides, or the addition of an adjuvant, can increase the risk of crop injury. (3) Application to perennial ryegrass and
fine fescue stands under stress may cause crop injury. (4) If weed escapes occur following a Dual Magnum application, an
application of a postemergence herbicide may be necessary to control escapes. When making such an application, follow
all directions, precautions and restrictions on the label of the postemergence herbicide. (5) Control may be decreased if
excessive straw from the previous harvest is present at application and/or insufficient rainfall/irrigation occurs.
Restrictions: (1) Do not graze forage regrowth for 60 days following application west of the Cascades. (2) In areas east of
the Cascades, do not graze forage regrowth for 150 days following application. (3) Hay may be harvested anytime between
seed harvest and the next application of S-metolachlor. (4) Apply Dual Magnum only once per crop year.
Apply a single application of Dual Magnum at a broadcast rate of 1.0-1.33 pt/A to the soil surface after planting, but before weeds or crop emergence (i.e., preemergence). Use lower rates on soils relatively coarse-textured and higher rates on fine-textured soils.

PUMPKIN – DUAL MAGNUM ALONE
Preemergence
Apply Dual Magnum preemergence (before the weeds have emerged) at 1.0 to 1.33 pt/A as an inter-row or inter-hill appli-
cation in pumpkin. Leave 1 foot of untreated area over the row, or 6 inches to each side of the planted hill and/or any
emerged pumpkin foliage (inter-row or inter-hill means not directly over the planted seed or young pumpkin plants). Use
the lower Dual Magnum rate on soils light in texture (loamy sand or lighter) and low in soil organic matter (less than 3%).
Dual Magnum applied as a broadcast spray over the planted row or hill, or applications made directly to crop foliage will
increase the risk of injury to the pumpkin crop such as stand loss, delayed maturity, and loss of yield. Do not apply Dual
Magnum closer than 30 days before pumpkin harvest.
Dual Magnum will not control emerged weeds. Control weeds that are present by another means, e.g., by mechanical means or by another herbicide.
Apply Dual Magnum at a broadcast rate of 0.67-1.33 pt/A to the soil surface in early spring, prior to crop emergence. Use lower rates on soils relatively coarse-textured and higher rates on fine-textured soils. A band application may also be used, applying proportionally less spray mixture on the area actually treated. Dual Magnum will not control emerged weeds. Control emerged weeds with an appropriate registered foliar herbicide or by mechanical or physical means.
Restrictions: (1) Make only one application of Dual Magnum per crop. (2) Do not apply more than 1.33 pt/A of Dual
Magnum per crop. (3) Preharvest Interval (PHI): Do not harvest rhubarb within 62 days of the Dual Magnum application.
SAFFLOWERS – DUAL MAGNUM ALONE
Preplant Incorporated or Preemergence: Follow instructions for use of Dual Magnum alone under Application Procedures.
On coarse soils, apply 1.0-1.33 pt/A of Dual Magnum if organic matter content is less than 3%, or 1.33 pt/A if organic matter
is 3% or greater. On medium soils, apply 1.33-1.67 pt/A of Dual Magnum. On fine soils, apply 1.33-1.67 pt/A of Dual Magnum
if organic matter content is less than 3%, or 1.67-2.0 pt/A if organic matter content is 3% or greater.
GRAIN OR FORAGE SORGHUM (SEED TREATED WITH CONCEP®) –
DUAL MAGNUM ALONE
Apply Dual Magnum preplant surface, preplant incorporated, preemergence or postemergence using the appropriate rate specified below. Apply Dual Magnum alone only when the sorghum seed has been properly treated with Concep seed treatment. Preplant or preemergence applications of Dual Magnum to sorghum not treated with Concep seed treatment will result in crop death.
Fall Application for Italian Ryegrass Control: Dual Magnum may be applied for residual control of glyphosate-resistant
Italian ryegrass (Lolium multiflorum). Apply Dual Magnum at 1.33-1.67 pt/A in the fall (September 1-December 1) after
harvest of the previous crop and prior to Italian ryegrass emergence. Use the lower Dual Magnum rate for coarse-textured
soils and the higher rate for fine-textured soils. A tillage operation may precede the application. Do not incorporate to
a depth greater than 2-3 inches if tillage follows the application of Dual Magnum. For fall applications after emergence
of glyphosate-resistant Italian ryegrass, Gramoxone brands can be tank mixed with Dual Magnum to control emerged
ryegrass. Refer to the Gramoxone brands label for specific rates, application instructions and restrictions. Other registered
herbicides may be tank mixed with Dual Magnum for control or improved control of other weeds present at the time of
application. Restrictions: (1) Do not apply Dual Magnum to frozen ground. (2) If a spring application is made, do not apply
Dual Magnum or any other product containing S-metolachlor the following spring to grain or forage sorghum.
Preplant Surface-Applied: Refer to instructions for use of Dual Magnum under the Application Procedures section on this
label. For minimum-tillage or no-tillage systems only, Dual Magnum may be applied up to 45 days before planting in CO,
IA, IL, KS, MO, NE, and SD. Use only split applications for treatments made 30-45 days prior to planting, with 2/3 of the
broadcast rate applied initially and the remaining 1/3 at planting. Apply 1.5 pt/A of Dual Magnum on medium soils or 1.67
pt/A on fine soils. Treatments less than 30 days prior to planting may be made either as a split or single application. Apply
1.33 pt/A of Dual Magnum on coarse soils not more than 2 weeks prior to planting. Under dry conditions, irrigate after
application to move Dual Magnum into the soil.
Preplant Incorporated or Preemergence: Refer to instructions for use of Dual Magnum under the Application Procedures
section on this label. Broadcast 1.0-1.33 pt/A of Dual Magnum on coarse soils, 1.33-1.5 pt/A on medium soils, or 1.33-1.67
pt/A on fine soils.
Postemergence: Refer to instructions for use of Dual Magnum under the Application Procedures section on this label.
Dual Magnum may be applied broadcast postemergence at 1.0-1.33 pt/A on coarse soils, 1.33-1.5 pt/A on medium soils, or
1.33-1.67 pt/A on fine soils. Dual Magnum will not control emerged weeds. Therefore, emerged weeds must be controlled
by cultural or chemical means. When applied alone, Dual Magnum will be safe to emerged sorghum. The risk of sorghum
injury increases when adjuvants (e.g., non-ionic, crop oil), Nitrogen sources (e.g., AMS, UAN) or fertilizers are applied with
Dual Magnum.
Precautions: (1) If sorghum seed is not properly treated with Concep seed treatment, preplant and preemergence applica-
tions of Dual Magnum will severely injure the crop. (2) Under high soil moisture conditions prior to sorghum emergence,
injury may occur following preplant and preemergence application of Dual Magnum. The crop will normally outgrow this
effect. (3) Do not use Dual Magnum on sorghum grown under dry mulch tillage, or injury may occur.
Restrictions: (1) Except for the split preplant surface treatment, do not make more than one application per year. (2) Post-
Harvest Interval (PHI): Do not apply Dual Magnum postemergence within 75 days of harvest.
GRAIN OR FORAGE SORGHUM (SEED TREATED WITH CONCEP) –
DUAL MAGNUM TANK MIXTURES
Dual Magnum preplant or preemergence (prior to sorghum emergence) tank mixtures with AAtrex may be applied in water or fluid fertilizer. Apply Dual Magnum preplant or preemergence tank mixtures only when the sorghum seed has been properly treated with Concep seed treatment. Preplant or preemeergence applications of Dual Magnum to sorghum not treated with Concep seed treatment will result in crop death.
IMPORTANT: FOR TANK MIXTURES WITH AATREX (OR OTHER BRANDS OF ATRAZINE) – If applying Dual Magnum in tank
mixture with AAtrex, all the restrictions and rate limitations on the AAtrex label must be followed if more restrictive/
protective than those on this label. In addition, if AAtrex is/must be applied at rates lower than those listed on this label,
broadleaf weed control may be affected. Refer to the AAtrex label for weeds controlled at the reduced rates.
Precautions: (1) Applications of Dual Magnum + AAtrex on highly alkaline soils or on eroded areas where calcareous sub-
soils are exposed may cause sorghum injury. (2) If sorghum seed is not properly treated with Concep, preplant and preemer-
ence applications of Dual Magnum + AAtrex may severely injure the crop. (3) Under high soil moisture conditions prior to
sorghum emergence, injury may occur following the use of preplant and preemergence applications of Dual Magnum +
AAtrex. The crop will normally outgrow this effect.
Restrictions: (1) Do not use Dual Magnum + AAtrex on sorghum grown under dry mulch tillage, or injury may occur. (2) Except
for the split preplant surface treatment, do not make more than one application per year.
TANK MIXTURE WITH AATREX

SUGAR BEETS – DUAL MAGNUM ALONE
Postemergence Applications
Dual Magnum may be applied postemergence to sugar beets after the sugar beets have reached the first true leaf stage.
However, because Dual Magnum is primarily a soil-active herbicide, it must be applied prior to weed emergence in order to
provide consistent control of listed weeds. As such, weeds that are emerged with or before the crop, or that are present at
the time Dual Magnum is applied, must be controlled with another appropriately labeled herbicide. Apply Dual Magnum
at 1 pt/A on coarse soils, 1.33 pt/A on medium soils, and 1.67 pt/A on fine soils. More than one postemergence application
may be applied, but the total must not exceed 2.6 pt/A. Weeds present at the time of application will not be controlled.
Restrictions: (1) Do not apply more than 2.67 pt/A postemergence. (2) Do not harvest within 60 days after the last application.
Precaution: In coarse soils, Dual Magnum applied before emergence of sugar beets (i.e., other than postemergence) may
cause injury.
SUGAR BEETS – DUAL MAGNUM TANK MIX COMBINATIONS
Dual Magnum may tank mixed with Assure® II, Betamix®, Betanex®, Poast®, Progress®, Select®, Stinger™, or Upbeet® and applied to sugar beets. Tank mixtures of these products with Dual Magnum will increase the risk of crop injury over that of either product applied alone, as the Dual Magnum formulation has some adjuvant properties. The addition of a spray adjuvant such as crop oil concentrates (COC's) or methylated seed oils (MSO's) can further increase the risk of crop injury. Injury risk can be reduced by using the lowest effective rate of the tank mix partner(s) and/or adjuvant and by avoiding applications under adverse growing conditions or high soil or air humidity. Refer to the individual product labels and follow all use restrictions and limitations.
SUNFLOWERS – DUAL MAGNUM ALONE
Preplant Incorporated or Preemergence
Within the rate ranges given below, use the higher rate of Dual Magnum if heavy weed infestations are expected. On
coarse soils with organic matter of less than 3%, apply 1.0-1.33 pt/A of Dual Magnum; 1.33 pt/A if organic matter is 3% or
greater. On medium soils, apply 1.33-1.67 pt/A of Dual Magnum. On fine soils with organic matter of less than 3%, apply
1.33-1.67 pt/A of Dual Magnum; 1.67-2.0 pt/A if organic matter content is 3% or greater.
Restrictions: (1) Do not allow livestock to graze or feed in treated area. (2) Do not exceed the maximum label rates given
above for sunflowers for the soil type.
TOMATOES – DUAL MAGNUM ALONE
Transplanted
Dual Magnum may be applied preplant incorporated or preplant before transplanting. If the latter method is used, keep
soil disturbance to a minimum during the transplanting operation. Application may also be made post-directed to trans-
plants after the first settling rain or irrigation. When an application is made post-directed, apply in a minimum of 20 gallons
of water per acre and minimize contact with tomato plants. Dual Magnum will not control emerged weeds. In bedded
transplanted tomatoes, apply Dual Magnum preplant non-incorporated to the top of the pressed bed, as the last step, prior
to laying plastic. Dual Magnum may also be used to treat row-middles in bedded tomatoes, as long as the total amount of
Dual Magnum does not exceed the maximum allowed per crop.
Seeded
Dual Magnum may be applied post-directed to direct seeded tomatoes. Tomato plants must be at least 4 inches tall at the
time of application and the product must be applied in a minimum of 20 gallons of water per acre. Minimize spray contact
with tomato plants. Dual Magnum will not control emerged weeds.
Tomato Use Rates: On coarse soils, apply 1.0-1.33 pt/A of Dual Magnum if organic matter content is less than 3% or 1.33
pt/A if organic matter is 3% or greater. On medium soils, apply 1.33-1.67 pt/A of Dual Magnum. On fine soils, apply 1.33-
1.67 pt/A of Dual Magnum if organic matter content is less than 3% or 1.67-2.0 pt/A if organic matter content is 3% or
greater.
Precautions: (1) Apply to varieties or cultivars with unknown tolerance to Dual Magnum may result in crop injury. (2) Dual Magnum may damage transplants that have been weakened by any cause. To prevent damage, plant only healthy trans-plants and avoid planting when wet, cool, or unfavorable growing conditions exist. (3) In transplanted tomatoes, if Dual Magnum is applied preplant incorporated, incorporate to a depth less than the depth of transplanting, and use the lower end of the rate range for the given soil type, or damage may occur. (4) For row middle applications where tomatoes are grown on sandy soils and where high soil moisture conditions can exist (e.g., low binding and high evaporation conditions), as may be found in the States of Florida, Georgia, Maryland, and Virginia, there is potential for crop injury in the form of leaf epinasty. The risk of this type of injury can be reduced by: a) incorporating the Dual Magnum immediately following application, b) applying the Dual Magnum seven or more days before transplanting (but only after the beds have been formed), c) minimizing the application of Dual Magnum onto the plastic of the bed, or d) any combination of the above. Do not exceed the maximum label rate for the soil texture per year.
Apply only by ground application.
90 Day PHI - If the single application rate of Dual Magnum is greater than 1.33 pt/A per year (up to 2.0 pt/A per year)
do not harvest tomatoes within 90 days of application.
30 Day PHI - If the application rate of Dual Magnum does not exceed 1.33 pt/A per year do not harvest tomatoes
within 30 days of application.
When applying at 1.33 pt/A per year with a 30 day PHI, the following restrictions apply:
• Do not exceed two applications per growing season.
• The use of adjuvants is prohibited.
• Applications may be made using ground equipment, in concentrated spray volumes.
•
Applications may be made as a foliar broadcast spray to the soil within a week of transplanting and again at
blooming/fruiting to the row middles as a banded/directed application 38-77 days after the fi rst treatment.
