DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
Do not use this product until you have read the entire label.

PRODUCT INFORMATION
OSPREY Herbicide is intended for application as a foliar spray in fall sown or winter wheat or fall sown triticale for the control of annual grass and broadleaf weeds. This product requires the addition of an adjuvant as specified in this label.

APPLICATION TIMING
Weed Application Timing
OSPREY Herbicide is a postemergent herbicide with best results being obtained when applications are made to young actively growing weeds. For annual (Italian) ryegrass and wild oat control, the weed application timing is from 1-leaf to the 2-tiller stage of growth. See weed tables for appropriate application timing and weed size. Treat heavy weed infestations before they become competitive with the crop.
Wheat and Triticale Application Timing
Apply OSPREY Herbicide to fall sown or winter wheat or fall sown triticale from emergence up to the jointing stage of growth.
Specific Regional Directions:
In California, apply OSPREY Herbicide from emergence to 2-tiller wheat (Feekes 5).
In Idaho, Oregon, and Washington states, OSPREY Herbicide may be applied from emergence up to the 2-node stage of wheat and fall sown triticale.

SPRAY ADDITIVES
OSPREY Herbicide is a water dispersible granule that does not include an adjuvant. A recommended adjuvant must be tank mixed with OSPREY Herbicide according to the guidelines as described in the Mixing Order section.
Application of OSPREY Herbicide must include a non-ionic surfactant plus ammonium nitrogen fertilizer or a methylated seed oil or a “basic blend” type adjuvant. Use only spray grade quality urea ammonium nitrogen fertilizer (28-0-0 to 32-0-0 at 1 – 2 qt/acre) or ammonium sulfate fertilizer (21-0-0-24 at 1.5 – 3 lbs/acre). When ammonium nitrogen fertilizer is used in tank mixture with OSPREY Herbicide, transient leaf burn may  occur.
Do not use additives that alter the spray solution below 6.0 pH. Best results are obtained at spray solution pH of 6.0 – 8.0.
Organosilicone-based surfactants or crop oil concentrate surfactants are not recommended for use with OSPREY Herbicide.

APPLICATION METHODS
Uniform, thorough spray coverage is important to achieve consistent weed control. The use of nozzles and spray pressure that deliver MEDIUM spray droplets as indicated in the nozzle manufacturer's catalogs and in accordance with ASAE Standard S-572 are highly recommended for optimum spray coverage and canopy penetration. Do not use flood-jet nozzles, controlled droplet application equipment, or cone nozzles. Use of certain nozzle types as described in the Spray Drift Management Factors section of this label may result in reduced coverage and weed control.
Ground Application
OSPREY Herbicide can be applied broadcast in 10 or more gallons of water per acre. For weed control in dense weed canopies, use 15 or more gallons of water per acre. Weed infestations should be treated before they become competitive with the  crop.
The use of 80-degree or 110-degree flat-fan nozzles is highly recommended for optimum spray coverage and canopy penetration. Use a spray pressure of 35 to 40 pounds per square inch (measured at the nozzle). Use screens that are 50 mesh or  larger.
Do not apply this product through any type of irrigation system.
Aerial Application
Calibrate the spray equipment prior to use. OSPREY Herbicide should be applied in a minimum of 5 gallons  of water per broadcast acre.  The use of nozzles and spray pressure that deliver MEDIUM spray droplets  as indicated in the nozzle manufacturer's catalogs and in accordance with ASAE Standard S-572 are highly recommended for optimum spray coverage and canopy penetration. DO NOT use raindrop nozzles. Aerial applications with this product should be made at a maximum height of 10 feet above the crop with low drift nozzles at a maximum pressure of 40 psi. Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur.
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 OSPREY Herbicide.

MIXING INSTRUCTIONS
OSPREY Herbicide must be applied with clean and properly calibrated equipment. Prior to adding OSPREY Herbicide to the spray tank, ensure that the spray tank, filters, and nozzles have been thoroughly cleaned.
Mixing Order
1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of OSPREY Herbicide.
3. Continue agitation until the OSPREY Herbicide is fully dispersed, at least 5 minutes.
4. Once OSPREY Herbicide is fully dispersed, maintain agitation and continue filling tank with water. OSPREY Herbicide should be fully mixed with water before adding any other material.
5. As the tank is filling, add the required amount of spray adjuvant (methylated seed oil or basic blend or non-ionic surfactant) and  ammonium nitrogen fertilizer. Add additional pesticide tank mix partner, if desired.
6. Continue agitation during herbicide application to ensure uniform spray coverage. If the mixture is not continuously agitated, settling may occur. If settling occurs, thoroughly re-agitate spray solution for at least 10 minutes before application. Use spray solution within 24 hours after mixing.

COMPATIBILITY
If OSPREY 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 1 qt) of spray solution, 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.

SPRAY DRIFT MANAGEMENT
OSPREY 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 and grower.

RESTRICTIONS FOR USE
Use adjuvants as specified on this label.
Do not apply OSPREY Herbicide to crops undersown with grass and legume species.
OSPREY Herbicide is rainfast 4 hours after application to most weed species. Rainfall within 4 hours may result in reduced weed control.
Applications should be made to actively growing weeds. Weed control may be reduced when weeds are under stress due to severe weather conditions, drought, very cold temperatures, etc. Weed control may be reduced if the herbicide application is made under dry, dusty conditions – especially in the wheel track areas.
Do not make more than one application of OSPREY Herbicide in one fall sown or winter wheat or fall sown triticale growing season.
Do not apply more than 4.75 oz/acre of OSPREY Herbicide in one fall sown or winter wheat or fall sown triticale growing season.
Do not apply more than 0.053 pounds of mefenpyr-diethyl per acre per year.
Do not apply when wind causes drift to off-site vegetation as injury may occur. Small amounts of OSPREY Herbicide via drift or tank contamination can cause severe damage to crops other than wheat. Careful management of spray drift and tank cleanout is required.
Applications of ammonium nitrogen fertilizer independent of those made with herbicides are commonly known as topdress applications. Topdress applications of ammonium nitrogen have been shown on occasion to result in transient leaf burn or stunting when applied within 14 days of an OSPREY Herbicide application.
Do not apply OSPREY Herbicide within 30 days of harvesting wheat or triticale forage, and 60 days for  hay,
grain, and straw.
Do not apply OSPREY Herbicide in tank mixture with malathion, mancozeb, Di-Syston or methyl   parathion
as unacceptable crop phytotoxicity may  occur.
Applications of OSPREY Herbicide in California should be made from emergence to 2-tiller wheat (Feekes 5).

STORAGE AND DISPOSAL    
Do not contaminate water, food or feed by storage or disposal.

PESTICIDE STORAGE
Store in a cool, dry place.
