GENERAL INFORMATION 
Option® Corn Herbicide is a sulfonylurea herbicide. Option® Corn Herbicide is intended for application as a foliar spray in corn for the 
control of annual and perennial grass and broad leaf weeds. Weed growth ceases within hours after Option® Corn Herbicide is applied. 
Symptoms progress from yellowing to necrosis resulting in eventual plant death within 1-3 weeks after application. 
Sulfonylurea herbicides have been associated with temporary yellowing or stunting. Corn quickly outgrows these effects and develops 
normally. Option®Corn Herbicide contains a safener which enhances the ability of corn to recover from any initial herbicide effects. 
Option® Corn Herbicide is for use on field corn, sweet corn and popcorn. Consult your local seed company agronomist prior to the use 
of Option Corn Herbicide on corn grown for seed (inbreds). Option® Corn Herbicide can be used on all types of field corn, including hi­
lysine, white and high oil corn. 
Injury arising from Option® Corn Herbicide due to hybrid sensitivity is the responsibility of the user. Follow seed company 
recommendation charts for hybrid sensitivity to SUlfonylurea herbicides or ALS inhibitors. 
2

Do not apply Option® Corn Herbicide to corn that exhibilsherbicide injury from previous applications of other herbicides. 
INSECTICIDE INTERACTION INFORMATION 
Soil Insecticide Interaction Information 
When Option® Corn Herbicide and organophosphate (OP) insecticides are applied to corn, the degradation of Option® Corn Herbicide 
is slower and corn injury can occur. DO NOT USE Option® Corn Herbicide in the same season as Counter® 15G, Counter® 20CR in 
furrow, Dyfonate® or Thimet®. 
For all corn hybrids, the following soil applied insecticides may be used prior to an application of Option® Corn HerbiCide: 
Soil Applied Insecticide Use Pattern Use of Option® Corn Herbicide in the Same 
Season 
AzteC® All No use precautions 
Capture®, Force®, Re[ent® All No use precautions 
Lorsban® 15G All Temporary injury may occur 
Counter® 20CR T-band Consult Counter® 20CR label 
Counter® 20CR In-furrow DO NOT USE 
Counter® 15G, Thimet®, All DO NOT USE 
Dyfonate® 
Foliar Insecticide Interaction Information 
Foliar applications of an OP insecticide should not be made within 7 days of an Option® Corn Herbicide application or injury may result. 
APPLICATION TIMING 
Weed Application Timing 
Option® Corn Herbicide is for postemergent use. Best results are obtained when applications are made to young actively growing. 
weeds. Option® Corn Herbicide will affect weeds that are larger than the recommended height, however, speed of activity and control 
may be reduced. 
Broadcast Corn Application Timing 
Broadcast applications of Option® Corn Herbicide must be made when corn is in the V1 through V6 growth stage. 
Late or Rescue Applications: 
Applications of Option Corn Herbicide at 1 3/4 ounces per acre may be applied to escaped weeds beyond labeled weed heights. In 
these situations, partial control and reduced weed competition can be expected. 
Drop Nozzles must be used for applications of Option® Corn Herbicide when corn is greater than V6 and less than V8 stage of growth. 
Do not apply to corn that is more mature than V8 (Le. more than 8 visible leaf collars) stage of growth. 
Yield loss due to competition: Research indicates competition from foxtail exceeding 4 inches in height may reduce corn yields. 
Applications to foxtail and other annual grasses that exceed the sizes stated on the label increases the risk of yield losses due to 
prolonged competition with the crop even though control may be acceptable. 
Applications of Option® Corn Herbicide on corn that is V7 to V8 increases the potential for crop response. The risk may be greatly 
reduced, put not eliminated, by using drop nozzles properly placed between corn rows to optimize coverage on the weeds and minimize 
spray contact in the whorl and the leaf axles of the corn stalks. 
SPRAY ADDITIVES 
Option® Corn Herbicide is a water dispersible granule that requires the use of an external adjuvant and nitrogen fertilizer. 
• Methylated or ethylated seed oil, containing at least 80% MSO and 10% emulsifier or greater, in combination with nitrogen 
fertilizer, is the recommended adjuvant type to provide optimum weed control with Option® Corn Herbicide. 
• " Non-ionic surfactants, crop oil concentrates, crop oil concentrate/methylated seed oil blends, and refined vegetable oils are not 
recommended for use with Option® Corn Herbicide. The use of these adjuvants in place of methylated seed oil will result in 
unacceptable weed control. 
• In areas of low relative humidity (west of highway 281, which begins in Texas and ends in North Dakota) Urea Ammonium Nitrate 
(UAN) is preferred over Ammonium Sulfate (AMS) and the higher rates listed in the following table are recommended. 
• The addition of nitrogen fertilizer replacements and/or insufficient amounts of n"itrogen fertilizer may result in reduced weed control. 
Recommended rates for methylated or ethylated seed oils and nitrogen fertilizers are listed in the following table:

1 For spray volumes of 19 gallons per acre or more, 1 % v/v of methylated or ethylated seed oil can be used. 
2 Nitrogen fertilizer must be used in combination with an adjuvant. 
APPLICATION METHODS 
1.5 -2 qts./acre 
1.5-3 Ibs/ac 
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. 
Do not use nozzles that produce FINE (e.g: - Cone) or EXTRA COARSE (e.g. - Flood jet) spray droplets. 
Ground Application 
Option® Corn Herbicide can be applied broadcast in a minimum of 10 gallons of water per acre. For weed control in dense weed 
populations or under adverse growing conditions, 15 to 20 gallons of water per acre is recommended. 
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. Refer to nozzle 
manufacturer catalogs. 
Air induction nozzles should be used at or near 80 psi to produce a medium droplet size. 
Aerial Application 
Option® Corn Herbicide should be applied in a minimum of 5 gallons of water per broadcast acre. Use nozzle types arrangements that 
will provide optimum spray distribution and maximum coverage. DO NOT use raindrop nozzles. Flagmen and loaders should avoid 
inhalation of spray mist and prolonged contact with skin. 
See the Spray Drift Management section of this label for additional information on proper application of Option® Corn Herbicide. 
Mixing Instructions 
Option® Corn Herbicide must be applied with clean and properly calibrated equipment. Prior to adding Option® Corn Herbicide, ensure 
that the spray tank, filters and nozzles have been thoroughly cleaned. 
1. Fill spray tank with 25% of the required volume of wate!, and begin agitation prior to the addition of Option® Corn Herbicide. 
2. Continue agitation to ensure full dispersion of Option® Corn Herbicide. 
3. If Option® Corn Herbicide is applied in a tank mixture with other pesticides, add Option® Corn Herbicide to the spray tank first 
and ensure it is thoroughly dispersed before adding other pesticides. If Option® Corn Herbicide is added to a partial tank of 
spray solution, pre-slurry Option® Corn Herbicide in clean water prior'to adding to the tank. 
4. Continue to' fill the spray tank with water to the desired volume and agitate while adding the required spray adjuvants and 
nitrogen fertilizers. If ammonium sulfate (AMS) is the nitrogen fertilizer source, it is preferred that the AMS go into the tank 
before the Option® Corn Herbicide. . 
5. Continue agitation during application to ensure a uniform spray mixture. 
RE-SUSPENDING WG PRODUCTS IN SPRAYSOLUTION 
Like other Water Dispersible Granules or suspension concentrates (SC's), Option® Corn 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. 
4

COMPATIBILITY 
If Option® Corn Herbicide is to be tank mixed with other herbicides, 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, do not use this mixture for spraying. Indications of incompatibility 
usually 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.

1. Drain the tank completely, then wash out tank, boom and hoses with clean water. Drain again. 
2. 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. 
3. Repeat Step 2. 
"4. Remove nozzles an"d screens and soak them in a 1 % ammonia solution. Inspect nozzles and screens and remove visible residues. 
5. Flush tank, boom, and hoses with clean water. 
6. Inspect tank for visible residues. If present, repeat Step 2. 
SPRAY DRIFT MANAGEMENT 
Option® Corn Herbicide is not volatile. Damage to sensitive crops can occur as a result of spray drift. Spray drift can be managed by 
several application factors and by spraying under the appropriate climatic conditions. Consequently, avoidance of spray drift is the 
responsibility of the applicator. 
7

SENSITIVE AREAS: The pesticide may 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, non-target plants) 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 for spray drift. The applicator and the grower are responsible for considering all these factors when 
making decisions. 
Do not apply under circumstances where possible drift to unproiected persons or to food, forage, or other plantings that might be 
damaged or crops thereof rendered unfit for sale, use or consumption can occur. 
The following drift management requirements must be followed to avoid off-target drift movemenl'from aerial applications to agricultural 
field crops. 
1. The distance of the outer most nozzles on the boom must not exceed 3/4 the length of the wingspan or rotor. 
2. Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees. 
3. All aerial and ground application equipment must be properly maintained and calibrated using appropriate carriers. 
Where states have more stringent regulations, they should be observed. The applicator should be familiar with and take into account 
the information covered in the Aerial Drift Reduction Advisory Information. 
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 airstream with aerial applications 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 to less than 3/4 of the wingspan or rotor length may further reduce drift 
without reducing swath width. 
APPLICATION HEIGHT: 
Applications should not be made at a height greater than 10 feet above the top of the largest plants unless a greater height is required 
for aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind. 
For ground boom applications, 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 downwind. Therefore, on the up and downwind edges of the 
field, the applicator must compensate for this displacement by adjusting the path of the aircraft upwind. Swath adjustment distance 
should increase, with increasing drift potential (higher wind, smaller drops, etc.) 
8

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. NOTE: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and 
how they affect spray drift. 
For all non-aerial applications, wind speed must be measured adjacent to the application site, on the upwind side, immediately prior to 
application. 
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. 
TEMPERATURE INVERSIONS: 
Do not make aerial or ground 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. continue into the 
morning. Their presence can be indicated by ground fog; however, if fog is not present, inversions can also be identified 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. 
ROTATIONAL GUIDELINES 
Option® Corn Herbicide rapidly degrades in the soil. This degradation is enhanced by warm moistsoils that are microbially active. 
If a corn crop has been destroyed by hail or other means soon after a Option® Corn Herbicide application, corn can be replanted 7 
days after an Option® Corn Herbicide application and soybeans can be planted 14 days after an Option® Corn Herbicide application. 
All other crops can be planted 60 days after an Option® Corn Herbicide application. 
RESISTANCE MANAGEMENT 
Some weed populations may contain plants naturally resistant to Option® Corn 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 of action in tank mixture, in 
sequence, rotation, or in conjunction with alternate cultural practices. Option® Corn Herbicide can be u~ed effectively as one of the 
modes of action in conjunction with Balance® Pro or Liberty® herbicides. 
PRECAUTIONS FOR USE 
1. Option® Corn Herbicide is rainfast 2 hours after application on most weed species. Rainfall within 2 hours may necessitate 
retreatment with Option® Corn Herbicide or may result in reduced weed control. Applications should be made to actively growing 
weeds. 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. 
2. DO NOT apply when wind causes drift to off-site vegetation as injury may occur. Small amounts of Option® Corn Herbicide 
delivered via drift or tank contamination can cause severe damage to other crops. Careful management of spray drift and tank 
cleanout is required. 
3. DO NOT apply more than two applicatio~s of Option® Corn Herbicide to corn in one growing season. 
4. DO NOT apply Option® Corn Herbicide within 70 days of harvesting corn grain or 45 days of harvesting corn forage or sweet corn 
ears. Do not graze within 45 days of an Option® Corn Herbicide application. 
5. DO NOT use nitrogen solutions as spray carriers. 
6. DO NOT apply this product through any type of irrigation system. 
7. Apply Option® Corn Herbicide spray mixtures within 24 hours of mixing to avoid product degradation. 
S. Do not apply in greenhouse. 
9. DO NOT apply more than 0.0765 Ib ai/A of foramsulfuron from all recommended application of EquipTM Corn Herbicide and 
Option® Corn Herbicide. 
10. Do not apply Option® Corn Herbicide by air in the state of New York.
