Environmental Hazards 
 
Cover or incorporate granules that are spilled during loading or are visible on soil 
surface in turn areas. 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. 
 
Groundwater Advisory 
 
S-metolachlor is known to leach through soil into groundwater under certain conditions 
as a result of label use. This chemical may leech into groundwater if used in areas 
where soils are permeable, particularly where the water table is shallow. 
 
Surface Water Advisory 
 
This product may impact surface water quality due to runoff of rain water through 
ground spray. This is especially true for poorly draining soils and soils with shallow 
groundwater. This product is classified as having high potential for reaching surface 
water via runoff for several weeks or months after application. 
A level, well-maintained vegetative buffer strip between areas to which this product is 
applied and surface water features such as ponds, streams, and springs will reduce the 
potential loading of S-metolachlor from runoff water and sediment. Runoff of this 
product will be reduced by avoiding applications when rainfall or irrigation is expected to 
occur within 48 hours. 
 
NON-TARGET ORGANISM ADVISORY 
This product is toxic to plants and may adversely impact the forage and habitat of non-
target organisms, including pollinators, in areas adjacent to the treated site. Protect the 
forage and habitat of non-target organisms by following label directions intended to 
minimize spray drift.

PRODUCT INFORMATION 
 
Dual IIG Magnum will control many annual grasses and certain broadleaf weeds in corn 
(all types), peanuts, potatoes, and soybeans. It should be applied prior to the 
emergence of weeds. It may be preplant surface-applied (corn and soybeans only), or 
incorporated into the surface 1-2 inches of soil before planting, or left on the soil surface 
during or after planting. Dry weather following an application of Dual IIG Magnum may 
reduce its effectiveness. Shallow cultivate if weeds develop or if tillage is necessary to 
improve the physical condition of the soil. 
 
Precaution: Injury may occur to crops other than corn following the use of Dual IIG 
Magnum under abnormally high soil moisture conditions during early development of 
the crop. To avoid reduced weed control or crop injury, do not apply to frozen ground or 
perform any operation that will unevenly distribute Dual IIG Magnum in the soil. In 
reduced tillage systems, injury may occur from movement of Dual IIG Magnum into the 
planter slit if the slit is not properly closed after planting. 
 
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: 
 
1. Avoid treating powdery dry or light sa nd soils when conditions are favorable for 
wind erosion. Under these conditions, the soil surface should first be settled by 
rainfall or irrigation. 
 
2. Do not apply to impervious substrates, such as paved or highly compacted 
surfaces. 
 
3. Do not use tailwater from the first flood or furrow irrigation of treated fields to treat 
nontarget crops, unless at least ½ inch of rainfall has occurred between 
application and the first irrigation.

Weed Resistance Management 
 
Dual IIG Magnum herbicide contains the active ingredient S-metolachlor which inhibits 
the formation of very long chain fatty acids (VLCFA, Site of Action Group 15). Some 
naturally occurring weed populations have been identified as resistant to Group 15 
herbicides. Selection of resistant biotypes, through repeated use of these herbicides or 
lower than recommended use rates in the same field, may result in weed control 
failures. A resistant biotype may be present where poor performance cannot be 
attributed to adverse environmental conditions or improper application methods. If 
resistance is suspected, contact your local Syngenta representative and/or agricultural 
advisor for assistance. 
 
Principles of Herbicide Resistant Weed Management 
Scout and know your field 
x Know weed species present in the field to be treated through scouting and field 
history. An understanding of weed biology is useful in designing a resistance 
management strategy. Ensure the weed management program will control all 
weeds present. 
x Fields should be scouted prior to application to determine species present and 
growth stage. Always apply this herbicide at the full labeled rate and correct 
timing for the weeds present in the field. 
 
Utilize non-herbicidal practices to add diversity 
x Use diversified management tactics su ch as cover crops, mechanical weed 
control, harvest weed seed control, and crop rotation as appropriate. 
 
Use good agronomic practices, start clean and stay clean 
x Use good agronomic practices that enhance crop competitiveness. 
x Plant into weed-free fields utilizing til lage or an effective burndown herbicide for 
control of emerged weeds. 
x Sanitize farm equipment to avoid spreading seed or vegetative propagules prior 
to leaving fields. 
 
Difficult to control weeds 
x Fields with difficult to control weeds should be planted in rotation with crops that 
allow the use of herbicides with an alternative mode of action or different 
management practices. 
x Difficult to control weeds may require sequential applications, such as a broad 
spectrum preemergence herbicide followed by one or more postemergence 
herbicide applications. Utilize herbicides containing different modes of action 
effective on the target weeds in sequential applications. 
 
Do not overuse the technology 
x Do not use more than two applications of this or any other herbicide with the 
same mode of action in a single growing season unless mixed with an herbicide

Dual IIG Magnum 
Page 9 
 
with a different mode of action which provides overlapping spectrum for difficult 
to control weeds. 
 
Scout and inspect fields following application 
x Prevent an influx of weeds into the fi eld by controlling weeds in field borders. 
x Scout fields after application to verify that the treatment was effective. 
x Suspected- herbicide resistant weeds may be identified by these indicators 
o Failure to control a weed species normally controlled by the herbicide at 
the dose applied, especially if control is achieved on adjacent weeds; 
o A spreading patch of non-controlled plants of a particular weed species; 
and 
o Surviving plants mixed with controll ed individuals of the same species. 
x Report non-performance of this product to your Syngenta retailer, Syngenta 
representative, or call 1-866-Syngent(a) (866-796-4368). If resistance is 
suspected ensure weed escapes are controlled using an herbicide with an 
effective mode of action and/or use non-chemical means to prevent further seed 
production. 
 
Prevent weed escapes before, during, and after harvest 
x Do not allow weed escapes to produce seed or vegetative structures such as 
tubers or stolons which contribute to spread and survival. Consider harvest 
weed seed management and control weeds postharvest to prevent seed 
production. 
 
Resistant Weeds 
x Contact your local Syngenta representative, retailer, crop advisor or extension 
agent to determine if weeds resistant to this mode of action are present in your 
area. If resistant biotypes have been reported, use the full labeled rate of this 
product, apply at the labeled timing, and tank-mix with a different mode of action 
product so there are multiple effective modes of application for each suspected 
resistant weed. 
 
 
MANDATORY SPRAY DRIFT MANAGEMENT 
Aerial Applications:
 
x Do not release spray at a height greater than 10 ft above the ground or vegetative 
canopy, unless a greater application height is necessary for pilot safety. 
x Applicators are required to select the nozzle and pressure that deliver medium or 
coarser droplets (ASABE S641). 
x If the wind speed is 10 miles per hour or less, applicators must use ½ swath 
displacement upwind at the downwind edge of the field. When the wind speed is 
between 11-
15 miles per hour, applicators must use ¾ swath displacement upwind 
at the downwind edge of the field. 
x •Do not apply when wind speeds exceed 15 mph at the application site. If the wind 
speed is greater than 10 mph, the boom length must be 65% or less of the wingspan 
for fixed wing aircraft and 75% or less of the rotor diameter for helicopters.

Dual IIG Magnum 
Page 10 
 
Otherwise, the boom length must be 75% or less of the wingspan for fixed-wing 
aircraft and 90% or less of the rotor diameter for helicopters. 
x Do not apply during temperature inversions. 
 
Ground Boom Applications: 
x User must only apply with the release height recommended by the manufacturer, but 
no more than 4 feet above the ground or crop canopy. 
x Applicators are required to select the nozzles and pressure that deliver medium or 
coarser droplets (ASABE S572). 
x Do not apply when wind speeds exceed 15 miles per hour at the application site. 
x Do not apply during temperature inversions. 
 
Boomless Ground Applications: 
x Applicators are required to select the nozzle and pressure that deliver medium or 
coarser droplet size (ASABE S572.3) for all applications. 
x Do not apply when wind speeds exceed 15 miles per hour at the application site. 
x Do not apply during temperature inversions. 
 
SPRAY DRIFT ADVISORIES 
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. 
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL 
CONDITIONS. 
 
IMPORTANCE OF DROPLET SIZE 
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets 
that provide target pest control. While applying larger droplets will reduce spray drift, the 
potential for drift will be greater if applications are made improperly or under unfavorable 
environmental conditions. 
 
Controlling Droplet Size – Ground Boom 
x Volume - Increasing the spray volume so that larger droplets are produced will 
reduce spray drift. Use the highest practical spray volume for the application. If a 
greater spray volume is needed, consider using a nozzle with a higher flow rate. 
x Pressure - Use the lowest spray pre ssure recommended for the nozzle to 
produce the target spray volume and droplet size. 
x Spray Nozzle - Use a spray nozzle that is designed for the intended application. 
Consider using nozzles designed to reduce drift. 
 
Controlling Droplet Size – Aircraft 
x Adjust Nozzles - Follow nozzle manufacturers’ recommendations for setting up 
nozzles. Generally, to reduce fine droplets, nozzles should be oriented parallel 
with the airflow in flight. 
 
BOOM HEIGHT – Ground Boom 
For ground equipment, the boom should remain level with the crop and have minimal 
bounce.

Dual IIG Magnum 
Page 11 
 
 
RELEASE HEIGHT - Aircraft 
Higher release heights increase the potential for spray drift. 
 
SHIELDED SPRAYERS 
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded 
sprayers. Verify that the shields are not interfering with the uniform deposition of the 
spray on the target area. 
 
TEMPERATURE AND HUMIDITY 
When making applications in hot and dry conditions, use larger droplets to reduce 
effects of evaporation. 
 
TEMPERATURE INVERSIONS 
Drift potential is high during a temperature inversion. Temperature inversions are 
characterized by increasing temperature with altitude and are common on nights with 
limited cloud cover and light to no wind. The presence of an inversion can be indicated 
by ground fog or 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 inversion, while smoke that moves upward and rapidly 
dissipates indicates good vertical air mixing. Avoid applications during temperature 
inversions. 
 
WIND 
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING 
GUSTY WIND CONDITIONS. 
Applicators need to be familiar with local wind patterns and terrain that could affect 
spray drift. 
 
SPRAY DRIFT ADVISORIES 
Boomless Ground Applications: Setting nozzles at the lowest effective height will help to 
reduce the potential for spray drift. 
 
SPRAY DRIFT ADVISORIES 
Handheld Technology Applications: Take precautions to minimize spray drift.

Weeds Partially Controlled*: common purslane, eclipta, Florida beggarweed**, hairy 
nightshade, sandbur, seedling johnsongrass, shattercane, volunteer sorghum, wild 
proso millet, and woolly cupgrass. 
 
*Control of these weeds can be erratic due partially to variable weather conditions. 
Control may be improved by following these suggested procedures: 
 
1. Thoroughly till moist soil to destroy germinating and emerged weeds. If Dual 
IIG Magnum is to be applied preplant incorporated, this tillage may be used to 
incorporate Dual IIG Magnum if uniform 2-inch incorporation is achieved as 
recommended under Application Procedures. 
 
2. Plant crop into moist soil immediately after tillage. If Dual IIG Magnum is to be 
used preemergence, apply at planting or immediately after planting, but before 
weed and/or crop emergence.

Dual IIG Magnum 
Page 13 
 
 
3. If available, sprinkler irrigate within 2 days after application so that a total of ½ 
inch of water (overhead sprinkler + rainfall) is available on coarse-textured soils 
and ¾-1 inch is available on medium- and fine-textured soils. 
 
4. 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, a 
uniform, shallow cultivation is recommended as soon as weeds emerge. 
 
**For partial control of this weed, use a minimum of 8 lbs./A and apply 
preemergence. 
 
APPLICATION PROCEDURES 
 
Application Timing 
 
Preplant Surface-Applied: For minimum-tillage or no-tillage systems only. Dual IIG 
Magnum alone may be applied up to 45 days before planting certain crops. Use only 
split applications for treatments made 30-45 days before planting, with ⅔ of the 
recommended broadcast rate for the crop and soil texture applied initially and the 
remaining ⅓ at planting. Treatments less than 30 days before planting may be made as 
either a split or a single application. If weeds are present at the time of treatment, apply 
a labeled contact herbicide (for example, Gramoxone Inteon® 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 may be diminished. 
 
Preplant Incorporated: Apply Dual IIG Magnum to the soil and incorporate into the top 
2 inches of soil within 14 days before planting. Use 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 to be used or if a period of dry 
weather after application is expected. If crop will be planted on beds, apply and 
incorporate Dual IIG Magnum after bed formation, unless specified otherwise. 
 
Preemergence: Apply Dual IIG Magnum during planting (behind the planter) or after 
planting, but before weeds or crops emerge. 
 
Fall Application (Only in IA, MN, ND, SD, WI, and portions of NE and IL – See 
specific instructions in the Corn and Soybean sections of this label for timing of 
application and other information): Do not apply to frozen ground. Use on medium- 
and fine-textured 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-inch incorporation depth if tilled after treatment. Note: 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.

Application Procedures 
 
Dual IIG Magnum may be applied either broadcast or banded. Do not apply Dual IIG 
Magnum during periods of high winds which could disrupt placement of the granules 
and reduce weed control. Locate granular diffusers as close to the ground as possible. 
Windshield attachments are advisable. 
 
Pneumatic (Compressed Air) Broadcast Application (Dual IIG Magnum Alone): 
Dual IIG Magnum may be applied through pneumatic dry fertilizer applicators which are 
equipped with special on-board herbicide metering bins. These metering units must be 
properly calibrated with Dual IIG Magnum prior to use. The placement of the granules 
in the applicator’s distribution system should be designed to minimize segregation of the 
granules from the dry fertilizer materials. 
 
Restriction: Dual IIG Magnum must never be blended with other pesticide formulations 
for application through on-board metering bins. Dual IIG Magnum must never be 
blender-mixed with liquid or dry fertilizer materials for broadcast pneumatic application. 
 
Broadcast Application (“Cyclone” or “Spinner” Type Spreaders): Dual IIG 
Magnum may be applied with a broadcast type (spinner) granular applicator or with a 
cyclone type spreader. Use applicators and techniques that will apply the granules 
uniformly to the soil. Do not blend Dual IIG Magnum with other pesticides or fertilizers. 
Always calibrate the device with Dual IIG Magnum prior to use. 
 
Variable-Rate Broadcast Ground Application for Corn and Soybeans: Variable-
rate technologies may be used for more precise applications. Two additive factors have 
been determined for use in applications using variable-rate technologies. One of these 
factors (A) is directly related to soil texture and the other (B) is related to percent 
organic matter (OM) and soil texture. When these two factors are added together, the 
resulting application rate will be more precise for a soil of a given soil texture and 
organic matter content. Use the formulas below to assure a more precise rate for any 
given area within a field.

Band Treatment: Dual IIG Magnum may be applied with any standard granular 
applicator capable of uniformly distributing a predetermined amount of granules to a 
desired area. Band treatment made at seeding should only be applied behind the press 
wheel. 
 
Note: Caution should be taken with planting equipment so that any track (soil 
depression) made by the planter press wheel is minimal. This will reduce concentration 
of granules in the press wheel track by heavy rain which can result in crop injury. Soil 
tillage should not follow the use of band applications, unless it is adapted so as not to 
displace the band and hence, reduce weed control in the band. In reduced tillage 
systems, injury may occur if the planter slit is not properly closed during planting. 
 
Applicator settings are given for band applications in Chart 1. These settings were 
determined under laboratory conditions to +5% accuracy. Note that the settings may 
differ depending on speed of application, as well as rate per acre. It is important that 
the user calibrate each individual granular applicator before its use. Since the

Dual IIG Magnum 
Page 16 
 
actual setting for each individual granular applicator may vary, the settings 
shown should serve only as guidelines for calibration. 
 
Calculate the amount of Dual IIG Magnum needed for band treatment as follows: 
 
Band width in inches X Broadcast rate = Band rate per 
Row spacing in inches per acre acre 
 
Example: If 15 lbs./A is recommended for broadcast application and you wish to treat a 
band 14 inches wide in crop rows spaced 30 inches apart: 
 
14/30 X 15 = 7.0 lbs. of granules needed for each acre that is to be treated

 *Settings are for application of the equivalent broadcast rates per acre indicated in a 14-inch 
band at speed (miles per hour) shown. If other than a 14-inch band is to be used, these 
settings do not apply and additional calibration will be necessary. 
 
**Example 1/83 - Gate 1: 1/3 way to 9th setting. 
 
Calibration of Band Applicators 
 
To calibrate a granular applicator for a standard 14-inch band, a sample has to be 
collected while the applicator is either running or simulating a run over a distance of 500 
ft.

Dual IIG Magnum 
Page 18 
 
Procedure 
 
1. Fill applicator box with Dual IIG Magnum. 
 
2. Refer to Chart 1 and adjust the setting on your applicator to correspond to the 
desired rate per acre. 
 
3. Attach a plastic bag or similar containe r to the applicator spout after detaching 
the delivery tube. 
 
4. Make the 500-ft. run at planting speed. 
 
Speed/Time required to cover 500 ft.: 
 
4 mph = 1 min. 25 sec. 
5 mph = 1 min. 8 sec. 
6 mph = 57 sec. 
 
5. Weigh granules collected (or measure volume) and, if necessary, adjust and 
make successive runs until the setting delivers the correct number of oz. per 500 
ft. of row, as shown in Chart 2. 
 
6. Repeat this procedure for each granular applicator box.

15 lbs. 4.5 fl. oz. 3.5 oz. 
 
For band widths other than 14 inches, the calibration distance will differ from 500 ft. 
 
For other band widths, calculate the relative calibration distance in which to collect the 
corresponding weight or volume of Dual IIG Magnum in Chart 2 as follows: 
 
14 (Inches) X 500 = Calibration distance 
Desired Band Width (Inches) in ft. 
 
Example: A band width of 10 inches is to be used, instead of 14 inches, to apply Dual 
IIG Magnum at an equivalent rate of 10 lbs. per broadcast acre.

CORN (ALL TYPES) 
 
CORN RATE RESTRICTIONS: 
1) Maximum Single Application Rate: 15 lb/A/application-(s-metolachlor 2.4 lb ai/A) 
2) Maximum Annual Rate: 23.2 lbs/A/year (3.71 lb ai/A/year) 
a. DO NOT exceed 3.71 lb ai/A/year of s-metolachlor containing products. 
 
For control of annual grasses and broadleaf weeds listed under the Product 
Information section, apply Dual IIG Magnum either preplant surface, preplant 
incorporated, or preemergence to corn before weeds emerge. For extended control of 
annual weeds, Dual IIG Magnum may be applied to weed-free soil at the time of the last 
cultivation (lay-by application) as either a surface or shallow incorporated treatment. 
Follow instructions for use of Dual IIG Magnum under Application Timing. 
 
Preplant Surface-Applied 
 
A. Fall Application: 
 
1. Apply after September 30 in ND, SD, MN, WI, and north of Route 30 in IA. 
2. Apply after October 15 north of Route 91 in NE and south of Route 30 in 
IA. 
3. 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 55qF and falling. Do not apply to 
frozen ground. In minimum-till or no-tillage systems on soils having greater than 
2.5% organic matter, use 10-15 lbs./A on medium-textured soils and 12-15 lbs./A 
on fine-textured soils. 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 inches. Minimize furrow and ridge formation in the tillage 
operations. Note: 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. 
 
B. Use on medium- and fine-textured so ils 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 of the recommended broadcast rate of Dual IIG Magnum shown in 
Table 1 as a split treatment 30-45 days before planting and the remaining 1/3 
immediately before planting, or at planting. Applications less than 30 days before 
planting may be made either as a split or as a single treatment. Apply 8 lbs./A

Dual IIG Magnum 
Page 20 
 
broadcast on coarse soils not more than 2 weeks before planting. If weeds are 
present at the time of treatment, apply a labeled contact herbicide (for example, 
Gramoxone Inteon or Roundup). Observe the 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. To avoid reduced weed control, do 
not apply to frozen soil as rainfall may change the distribution pattern of the Dual 
IIG Magnum granules. Injury may occur from movement of Dual IIG Magnum into 
the planter slit if the slit is not properly closed during planting. 
 
C. 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 could be used, i.e., AAtrex®, Beacon®, Bicep 
Magnum®, Bicep II Magnum®, Exceed®, Accent®, Banvel®, Basagran®, 
bromoxynil (Brominal or Buctril®), or 2,4-D. Observe all directions for use, 
precautions, and limitations on the label of the postemergence herbicide. 
 
Preplant Incorporated: Using the appropriate rate from Table 1, broadcast Dual IIG 
Magnum to the soil and uniformly incorporate within the top 1-2 inches of soil within 14 
days before planting, using appropriate surface incorporating equipment, such as a 
finishing disk, harrow, rolling cultivator, or similar implement capable of providing 
uniform incorporation. 
 
Preemergence: Band or broadcast Dual IIG Magnum to the soil surface during or after 
planting and before weeds emerge, using the appropriate rate from Table 1. For band 
treatment, apply granules behind the press wheel. In reduced tillage systems, injury 
may occur from movement of Dual IIG Magnum into the planter slit if the slit is not 
properly closed during planting. 
 
Restriction for All Applications to Corn: To avoid possible illegal residues, (1) do not 
graze or feed forage from treated areas for 30 days following application and (2) do not 
harvest sweet corn ears from treated areas for 30 days following application.

incorporate into the top 3 inches before planting, using a finishing disk, harrow, rolling 
cultivator, or similar implement. Planting and later cultural practices should avoid 
bringing untreated soil to the surface. Postplant incorporated application may be made 
any time after planting to drag-off, but before potato emergence. Incorporate, using an 
implement that distributes Dual IIG Magnum within the top 1-2 inches of soil. Do not 
damage potato seed pieces or sprouts with incorporation equipment. 
 
Preemergence: Apply Dual IIG Magnum at 6-12 lbs./A broadcast, either after planting 
as a preemergence, delayed preemergence, after drag-off or hilling treatment, but 
before weeds emerge. Up to 15 lbs./A of Dual IIG Magnum broadcast may be used 
where soil organic matter is between 6% and 20%. 
 
Restrictions and Precautions: (1) Do not use on muck or peat soils. (2) If cool, wet soil 
conditions occur after application, Dual IIG Magnum may delay maturity and/or reduce 
yield of Superior and other early maturing potato varieties. To avoid crop injury, (3) Do 
not use on sweet potatoes or yams. (4) Do not apply both preemergence and 
incorporated treatments to the same crop, and (5) Do not use on potatoes in Kern 
County, CA. 
 
Restriction: To avoid illegal residues, potatoes treated with Dual IIG Magnum must not 
be harvested within 60 days after the last application.

replanted immediately. Do not make a second broadcast application of Dual IIG 
Magnum. If the original application was banded and the second crop is planted in the 
untreated row middles, a second banded treatment may be applied. (2) Barley, oats, 
rye, or wheat may be planted 4 1/2 months following application; alfalfa may be planted 
4 months following application. (3) Any crop on this label in addition to cotton, cabbage, 
peppers, pod crops, safflowers, grain or forage sorghum*, root crops, tobacco, barley,
