GROUND APPLICATION
3
lodosulfuron 10 WDG Herbicide may be applied after the fall harvest and at least 30 days prior to planting field corn, cereals and grain 
and forage sorghum, or at least 60 days prior to planting soybean, sweet corn, popcorn, or corn grown for seed. Do not apply to frozen 
ground. Best results are obtained when applications are made to actively growing weeds, lodosulfuron 10 WDG Herbicide will affect 
weeds that are larger than the listed height, however, speed of activity and control may be reduced. lodosulfuron 10 WDG Herbicide will 
provide short term residual of small seeded broadleaf weeds.
lodosulfuron 10 WDG Herbicide may be applied as a broadcast treatment in a minimum of 10 gallons of water per acre. For weed 
control in dense weed populations, control of weeds under adverse growing conditions, or control of mature weeds use higher spray 
volumes up to 30 gallons per acre.
lodosulfuron 10 WDG Herbicide will not provide season-long preemergence control of annual grass and broadleaf weeds, 
-For extended control in LibertyLink®, glufosinate-tolerant corn, follow lodosulfuron 10 WDG Herbicide with an in-season 
application of LIBERTY herbicide.
-For extended control in conventional corn, follow lodosulfuron 10 WDG Herbicide with sequential programs based on targeted 
weeds. Such programs include Balance® Flexx, Corvus®, Capreno™ and Laudis®.
-For season long control in soybean, follow lodosulfuron 10 WDG Herbicide with a sequential program based on targeted 
weeds.
DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. 
Read entire label before using this product.
Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers 
may be in the same area during application. For any requirements specific to your State or Tribe, consult the agency responsible for 
pesticide regulation.
USE INFORMATION
lodosulfuron 10 WDG Herbicide is a sulfonylurea herbicide, lodosulfuron 10 WDG may be used for bumdown of existing vegetation and 
residual weed control when applied to no-till or conservation tillage fields anytime after the fall harvest. Do not apply to frozen ground. 
Weed growth ceases within hours after lodosulfuron 10 WDG Herbicide is applied. Symptoms progress from yellowing to necrosis 
resulting in eventual plant death within 1-4 weeks after application.
lodosulfuron 10 WDG Herbicide is a water dispersible granule that requires the use of an external adjuvant and nitrogen fertilizer.
• The addition of Crop Oil Concentrate at 1 % v/v (1 gallon per 100 gallons of final spray volume) is required.
• The addition of nitrogen fertilizer (28 or 32% Urea Ammonium Nitrate at 1.5-2 qts/A or Spray Grade Ammonium Sulfate at 1.5- 
3.0 Ibs/A) is required.
APPLICATION METHODS
Uniform, thorough spray coverage is important to achieve consistent weed control.
AGRICULTURAL USE REQUIREMENTS
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This standard contains 
requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural 
pesticides. It contains requirements for training, decontamination, notification and emergency assistance. It also contains specific 
instructions and exceptions pertaining to the statements on this label about Personal Protective Equipment (PPE) and restricted entry 
intervals. The requirements in this box only apply to uses of this product that are covered by the Worker Protection Standard. 
Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 12 hours.
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with 
anything that has been treated such as plants, soil or water, is coveralls over long-sleeved shirt and long pants, socks and shoes and 
chemical resistant gloves made of any waterproof material.

SPRAY DRIFT
GROUND BOOM
BOOM HEIGHT
WIND
4
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. For ground equipment, the 
boom should remain level with the crop and have minimal bounce.
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.
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.
Controlling Droplet Size
• 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.
• Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size.
• Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift.
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.
Ground Boom Applications
• Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy unless 
making a turf, pasture, or rangeland application, in which case applicators may apply with a nozzle height no more than 4 feet 
above the ground.
• For applications prior to the emergence of crops and target weeds, applicators are required to use a Coarse or coarser droplet size 
(ASABES572.1).
• For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE S572.1).
• Do not apply when wind speeds exceed 10 miles per hour at the application site.
• Do not apply during temperature inversions.
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.

If ammonium sulfate (AMS) is the nitrogen fertilizer source, it is preferred that the AMS go into the spray tank prior to lodosulfuron 
10WDG Herbicide.
Fill spray tank with 25% of the required volume of water, and begin agitation prior to the addition of lodosulfuron 10 WDG 
Herbicide.
Continue agitation to ensure full dispersion of lodosulfuron 10 WDG Herbicide. 
If lodosulfuron 10 WDG Herbicide is applied in a tank mixture with other pesticides, add lodosulfuron 10 WDG Herbicide to the 
spray tank first and ensure it is thoroughly dispersed before adding other pesticides. 
Continue to fill the spray tank with water to the desired volume and agitate while adding spray adjuvants and nitrogen fertilizers. 
Continue agitation during application to ensure a uniform spray mixture. (If lodosulfuron 10 WDG Herbicide is added to a partial 
tank of spray solution, pre-slurry lodosulfuron 10 WDG Herbicide with clean water prior to adding to the spray tank).
Windblown Soil Particles Advisory
WINDBLOWN SOIL PARTICLES: lodosulfuron 10 WDG Herbicide has the potential to move off-site due to wind erosion. Soils that are 
subject to wind erosion usually have a high silt and/or fine to very fine sand fractions and low organic matter content. Other factors 
which can affects the movement of windblown soil include the intensity and direction of prevailing winds, vegetative cover, site slope, 
rainfall, and drainage patterns. Avoid applying lodosulfuron 10 WDG Herbicide if prevailing local conditions may be expected to result in 
off-site movement.

Mixing Instructions
lodosulfuron 10 WDG Herbicide must be applied with clean and properly calibrated equipment. Prior to adding lodosulfuron 10 WDG 
Herbicide, ensure that the spray tank, filters and nozzles have been thoroughly cleaned.
Weed Resistance
ALS-resistance exists in some biotypes. These biotypes will not be controlled by lodosulfuron 10 WDG Herbicide. Consider 
using herbicides with other modes of actions such as 2,4-D to control these species.
COMPATIBILITY
If lodosulfuron 10 WDG Herbicide is to be tank-mixed with other pesticides not listed specifically on this label, compatibility should be 
tested prior to mixing. To test for compatibility, use a small container and mix a small amount (0.5 to 1 qt) of spray, combining all 
ingredients in the same ratio as the anticipated use. If any indications of physical incompatibility develop (precipitation, settling, changes 
in color) do not use this mixture for spraying. Indications of incompatibility may occur within 5-15 minutes after mixing. Read and follow 
the label of each tank mix product used for precautionary statements, directions for use, geographic and other restrictions.
RE-SUSPENDING WDG PRODUCTS IN SPRAY SOLUTION
Like other water dispersible granules or suspension concentrates (SC ’s), lodosulfuron 10 WDG Herbicide will settle if left standing 
without agitation. If the spray solution is allowed to settle for one hour or more, re-agitate the spray solution for a minimum of 10 
minutes before application.
WEED CONTROL INSTRUCTIONS
Rate Tables for Weed Control
lodosulfuron 10 WDG Herbicide may be applied at a rate of up to a maximum of 0.3 ounces of product per acre (0.001875 lbs active

ROTATIONAL CROP DIRECTIONS
lodosulfuron 10 WDG Herbicide rapidly degrades in the soil. This degradation is enhanced by warm moist soils that are 
microbially active. Rotational intervals to crops are illustrated below.
TANK CLEANUP PROCEDURE
Drain the tank completely, then wash out tank, boom, and hoses with clean water. Drain again. 
Fill the tank half full with clean water and add ammonia (i.e., 3% domestic ammonia solution) at a dilution rate of 1% (i.e., 1 
gallon of domestic ammonia for every 100 gallons of rinsate). Completely fill the tank with water. Agitate/recirculate and 
flush through boom and hoses. Leave agitation on for 10 minutes. Drain tank completely. 
Repeat Step 2.
Remove nozzles and screens and soak them in a 1% ammonia solution. Inspect nozzles and screens and remove visible 
residues.
Flush tank, boom, and hoses with clean water. Inspect tank for visible residues. If present, repeat Step 2.

OTHER CROPS
All other crops may be seeded only after the completion of a successful field bioassay after an lodosulfuron 10 WDG Herbicide 
application. Refer to the “Field Bioassay ” section.
DO NOT apply more than a total of 0.001875 lbs active ingredient of iodosulfuron per acre in a single calendar year. 
(Equivalent to 0.3 oz of product).
DO NOT apply when wind causes drift to off-site vegetation, as injury may occur. Small amounts of lodosulfuron 10 
WDG Herbicide delivered via drift or spray tank combinations can damage other plants. Carefully manage spray drift 
and tank cleanout.
DO NOT apply this product by air or through any type of irrigation system.
When this product is used as a post-harvest bumdown application, no other product containing active ingredient 
iodosulfuron may be applied for any other use in the same calendar year on the same acreage. 
Do not make more than 1 application per year.
For Field corn, cereals and grain or forage sorghum, use as a post-harvest burndown application in the fall at least 30 
days prior to planting.
For sweet corn, popcorn, or corn grown for seed, soybean and cotton use as a post-harvest burndown application in 
the fall at least 60 days prior to planting.
FIELD BIOASSAY
Afield bioassay must be completed before rotating to crops other than those specified in the “Rotational Crop Directions ” 
section of this label. To conduct an effective field bioassay, grow strips of the crop you intend to grow in the following season in 
a field previously treated with lodosulfuron 10 WDG Herbicide. The test strip should include low areas and knolls, and include 
variations in soil such as type and pH. Crop response to the bioassay will determine if the crop(s) grown in the test strips can be 
grown safely in the areas previously treated with lodosulfuron 10 WDG Herbicide.
HERBICIDE RESISTANCE MANAGEMENT (WSSA) RECOMMENDATIONS
For resistance management, lodosulfuron 10 WDG Herbicide is a Group 2 herbicide. Any weed population may contain or 
develop plants naturally resistant to lodosulfuron 10 WDG Herbicide and other Group 2 herbicides. The resistant biotypes may 
dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate resistance management 
strategies should be followed.
To delay herbicide resistance take one or more of the following steps:
• Rotate the use of lodosulfuron 10 WDG Herbicide or other Group 2 herbicides within a growing season sequence or 
among growing seasons with different herbicide groups that control the same weeds in a field.
• Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in 
target weed species is available, use the less resistance-prone partner at a rate that will control the target weed(s) 
equally as well as the more resistance-prone partner. Consult your local extension service or certified crop advisor if 
you are unsure as to which active ingredient is currently less prone to resistance.
• Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical 
information related to herbicide use and crop rotation, and that considers tillage ( or other mechanical control 
methods), cultural ( e.g., higher crop seeding rates; precision fertilizer application method and timing to favor the crop 
and not the weeds), biological (weed-competitive crops or varieties) and other management practices.
• Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of 
possible herbicide resistance include; (1) failure to control a weed species normally controlled by the herbicide at the 
dose applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a 
particular weed species; (3) surviving plants mixed with controlled individuals of the same species. If resistance is 
suspected, prevent weed seed production in the affected area by an alternative herbicide from a different group or by a 
mechanical method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning 
harvesting and tillage equipment when moving between fields, and planting clean seed.
• If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and 
switch to another management strategy or herbicide with a different mode of action, if available.
• Contact your local extension specialist or certified crop advisors for additional pesticide resistance-management and/or 
integrated weed-management recommendations for specific crops and weed biotypes,
• For further information or to report suspected resistance contact Bayer CropScience at 1-866-99BAYER (1-866-992-
2937). You can also contact your pesticide distributor or university extension specialist to report resistance.
