+APPLICATION TIMING
+SPRAY ADDITIVES
+Do not apply lodosulfuron 10 WDG Herbicide using aerial application.
+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.

+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

+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.
