+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

+SPRAY DRIFT MANAGEMENT l" , 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.

+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

+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' '
