C c GENERAL INFORMATION lodosulfuron 10 WDG Herbicide is a sulfonylurea herbicide, lodosulfuron may be used for burndown of existing vegetation and residual weed control when applied to no-till or conservation tillage fields anytime after the fall harvest of soybean. Do not apply to frozen ground. Weed growth ceases within hours after lodosulfuronIO 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 will not provide season-long preemergence control of annual grass and broadleaf weeds. -for season long control in soybean, follow lodosulfuronIO WDG Herbicide with a sequential program based on targeted weeds. APPLICATION TIMING lodosulfuron 10 WDG Herbicide should be applied after the fall harvest and up to 90 days prior to soybean planting. Do not apply to frozen ground. Best results are obtained when applications are made to actively growing weeds. lodosulfuronIO WDG Herbicide will affect weeds that are larger than the listed height, however, speed of activity and control may be reduced. lodosulfuronIO WDG Herbicide will provide short term residual of small seeded broadleaf weeds. SPRAY ADDITIVES lodosulfuronIO 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/acre or Spray Grade Ammonium Sulfate at 1.5-3.0 Ibs/acre) is required. APPLICATION METHODS Uniform, thorough spray coverage is important to achieve consistent weed control. Select spray nozzles and pressure that deliver MEDIUM spray droplets as indicated in nozzle manufacturer's catalogs and in accordance with ASAE Standard S-572. Nozzles that deliver COARSE spray droplets may be used to reduce spray drift provided spray volume per acre (GPA) is increased to maintain coverage of weeds. Do not use nozzles that produce FINE (e.g. - Cone) or EXTRA COARSE (e.g. - Flood jet) spray droplets. Do not apply lodosulfuronIO WDG Herbicide using aerial application. GROUND APPLICATION lodosulfuronIO 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. Typically flat fan nozzles operated at 30-60 PSI will deliver MEDIUM spray droplets, providing optimum spray coverage and canopy penetration. Lower pressure operation and/or higher volume flat fan nozzles, typically deliver COARSE sprays. Refen'.o npzile manufacturer catalogs. i' ' tc u i t r- l

'• <• L lodosulfuronl 0 WDG Herbicide is not volatile. Damage to sensitive crops can occur as a result of spray drift. S^ray drift can be managed by several application factors and by spraying under appropriate climatic conditions. Consequently', avoidance of spray drift is the responsibility of the applicator. «. L «. 111

SENSITIVE AREAS: The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g. residential areas, bodies of water, known habitats for threatened or endangered species, non-target crops) is minimal (e.g. when wind is blowing away from the sensitive areas). Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment-and-weather-related factors determine the potential or spray drift. The applicator and the grower are responsible for considering tall these factors when making decisions. Do not apply under circumstances where possible drift to unprotected persons or to food, forage, or other plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption can occur. 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, Temperature and Humidity, and Temperature inversions below). Uniform, thorough spray coverage is important to achieve consistent weed control. Select nozzles and pressure that deliver MEDIUM spray droplets as indicated in nozzle manufacturer's catalogs and in accordance with ASAE Standard S-572. Nozzles that deliver COARSE spray droplets may be used to reduce spray drift provided spray volume per acre (GPA) is increased to maintain coverage of weeds. 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 recommended 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 air stream produces larger droplets than other orientations and is the recommended 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. BOOM LENGTH: For some use patterns, reducing the effective boom length may further reduce drift without reducing swath width. APPLICATION HEIGHT: Apply with nozzle height no more than 4 feet above the ground or crop canopy. SWATH ADJUSTMENT: /— When applications are made with a crosswind, the swath will be displaced downward. Therefore, on the up and downwind edges of the ^ field, the applicator must compensate for this displacement by adjusting the path of the sprayer upwind. Swath adjustment distance should increase, 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. Application should be avoided below 2 mph due to variable wind direction and high inversion potential. Wind speed must be measured adjacent to the application site, on the upwind side, immediately prior to application. NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. TEMPERATURE AND HUMIDITY: When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry. Avoid spraying during conditions of low humidity and/or high temperatures. cLI"CCc TEMPERATURE INVERSIONS: c11' l . ( t, t L • Do not make applications into areas of temperature inversions. Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. This cloud can move in unpredictable '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 'opntinJe into the morning. Their presence can be indicated by ground fog; however, if fog is not present, inversionslc'ah''e!so be identified by the movement of smoke from a ground source. Smoke that layers and moves laterally in a conceijtretpr1 ^cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing.

C c c Mixing Instructions lodosulfuron 10 WDG Herbicide must be applied with clean and properly calibrated equipment. Prior to adding lodosulfuronIO WDG Herbicide, ensure that the spray tank, filters and nozzles have been thoroughly cleaned.

1. Fill spray tank with 25% of the required volume of water, and begin agitation prior to the addition of lodosulfuronIO WDG Herbicide.
2. Continue agitation to ensure full dispersion of lodosulfuronIO WDG Herbicide.
3. If lodosulfuronIO WDG Herbicide is applied in a tank mixture with other pesticides, add lodosulfuronIO WDG Herbicide to the spray tank first and ensure it is thoroughly dispersed before adding other pesticides.
4. Continue to fill the spray tank with water to the desired volume and agitate while adding spray adjuvants and nitrogen fertilizers.
5. Continue agitation during application to ensure a uniform spray mixture. (If lodosulfuronIO WDG Herbicide is added to a partial tank of spray solution, pre-slurry lodosulfuronIO WDG Herbicide with clean water prior to adding to the spray tank). If ammonium sulfate (AMS) is the nitrogen fertilizer source, it is preferred that the AMS go into the spray tank prior to lodosulfuronIO WDG Herbicide. RE-SUSPENDING WDG PRODUCTS IN SPRAY SOLUTION Like other Water Dispersible Granules or suspension concentrates (SC's), lodosulfuronIO 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. COMPATIBILITY If lodosulfuronIO 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 1qt) 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. WEED CONTROL INSTRUCTIONS Rate Instructions Tables for Weed Control lodosulfuron 10 WDG Herbicide should be applied at a rate of 0.001875 Ibs of active ingredient (0.3 ounces of product) per acre in crop stubble for the control of certain broadleaf weeds up to 3 inches in height and annual grasses no greater than 1 inch in height. Weeds controlled are listed below: Alfalfa Pennycress Annual Bluegrass Purple deadnettle Blue Mustard Purselane Broadleaf plantain Redroot pigweed Burcucumber Scentless Chamomile Burdock Shepherd's purse Buttercup Sunflower Common chickweed Tansy mustard Dandelion Turnip weed Field pennycress Volunteer canola Hemp Nettle Wild Carrot Henbit Wild mustard Horsenettle Wild radish Mouse-eared chickweed Weed Resistance ALS-resistance exists in some biotypes. These biotypes will not be controlled by lodosulfuronIO WDG Herbicide. Consider using herbicides with other modes of actions such as 2,4-D to control these species. Tank Mixes !.,.«.. I ..lodosulfuron 10 WDG Herbicide can be tank mixed with 2,4-D for enhanced burn down activity, lodosulfuron 10 WDG can also be tank mixed with glyphosate, paraquat, or Sencor for fields to be planted to soybean.

u ROTATIONAL CROP DIRECTIONS lodosulfuronlO 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. Crop Alfalfa Barley (Spring) Barley (Winter) Canola Cotton* Corn Dry Beans Grain or Forage Sorghum Oats Peas, Snap Beans Potatoes Red Clover Rice Rye (winter) Soybeans Sugarbeets Sunflowers Wheat (Spring) Wheat (Winter) All other crops Rotational Interval 18 months 8 months 4 months 18 months 9 months 30 days 18 months 9 months 9 months 18 months 18 months 18 months 18 months 4 months 90 days 1 8 months 1 8 months 8 month 4 months 18 months c c 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. *East of Interstate 35, planting of cotton must wait 18 months when soil pH is greater than 7.5 and when less than 15" of annual precipitation has occurred following an application of lodosulfuron 10 WDG Herbicide. FIELD BIOASSAY A field 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 lodosulfuronlO 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. RESISTANCE MANAGEMENT Some weed populations may contain plants naturally resistant to lodosulfuronlO WDG Herbicide or other herbicides with the same mode of action (ALS/AHAS enzyme inhibitors). Repeated use of herbicides with the same mode of action, allow resistant weeds to spread. To manage the development and spread of resistant weed populations, use herbicides with different modes oi action in tank mixture, rotation, or in conjunction with alternate cultural practices. !.c l L' '

c USE RESTRICTIONS AND PRECAUTIONS

1. DO NOT apply more than a total of 0.001875 Ibs active ingredient lodosulfuron per acre in a single calendar year. (Equivalent to 0.3 ounces product)
2. Rainfall within 2 hours may necessitate re-treatment with lodosulfuronIO WDG Herbicide and may result in reduced weed control. Established weeds should be actively growing when the herbicide application is made. Weed control may be reduced if application is made when weeds are dust covered or in the presence of heavy dew, fog, and mist/rain or when weeds are under stress due to drought.
3. DO NOT apply when wind causes drift to off-site vegetation, as injury may occur. Small amounts of lodosulfuronIO WDG Herbicide delivered via drift or spray tank combinations can damage other plants. Carefully manage spray drift and tank cleanout.
4. DO NOT apply this product by air or through any type of irrigation system.
5. Apply lodosulfuronIO WDG Herbicide spray mixtures within 24 hours of mixing to avoid product degradation.
