PRODUCT INFORMATION OSPREY Xtra Herbicide: x 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. Best weed control is obtained when OSPREY Xtra Herbicide is applied to young actively growing weeds in vigorously growing fall sown or winter wheat that will shade competitive weeds. x Is absorbed through the foliage of plants, rapidly inhibiting growth of susceptible weeds. Visual symptoms progress from yellowing to necrosis of the growing point and eventual plant death. Abnormal environmental conditions (excess soil moisture or drought, extreme cold weather) can influence crop tolerance and herbicidal activity and may cause temporary damage to the crop or reduce levels of weed control. This may result in weed stunting, rather than weed death. However, weed competition will be greatly reduced, and should permit normal crop development. Crop response may occur when frost occurs shortly after application to actively growing wheat. x Is rainfast 4 hours after application to most weed species. Rainfall within 4 hours may result in reduced weed control.

MANDATORY SPRAY DRIFT MANAGEMENT

Aerial Applications: x Nozzles must be oriented so the spray is directed toward the back of the aircraft. x Do not release spray at a height greater than 10 ft above the ground or vegetative canopy, unless a greater application height is necessary for pilot safety. x Applicators are required to use a medium or coarser droplet size (ANSI/ASABE S641) for all applications. x Applicators must use ½ swath displacement upwind at the downwind edge of the field. x Do not apply when wind speeds exceed 10 mph at the application site. The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade diameter for helicopters. x Do not apply during temperature inversions.

Ground Boom Applications: x Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the ground or crop canopy. x Applicators are required to use a medium or coarser droplet size (ANSI/ASAE S572.3). x Do not apply during temperature inversions. x Do not apply when wind speeds exceed 10 miles per hour at the application site.

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.

Ground Boom Controlling Droplet Size x 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. x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift. Boom Height x For ground equipment, the boom should remain level with the crop and have minimal bounce.

Aircraft Controlling Droplet Size x Adjust Nozzles - Follow nozzle manufacturer’s recommendations for setting up nozzles. Generally, to reduce fine droplets, nozzles should be oriented parallel with the airflow in flight. Release Height x Higher release heights increase the potential for spray drift.

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.

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.

Wind 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.

Windblown Soil Particles OSPREY Xtra 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 OSPREY Xtra Herbicide if prevailing local conditions may be expected to result in off-site movement.

WEED RESISTANCE MANAGEMENT For resistance management, OSPREY Xtra Herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to OSPREY Xtra 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: x Rotate the use of OSPREY Xtra Herbicide or other Group 2 he rbicides within a growing season sequence or among growing seasons with different herbicide groups that control the same weeds in a field. x 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

6

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. x Adopt an integrated weed-management program for herbicide use th at 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. x Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of possibl e 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. x 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. x 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. x For further information or to report suspected resistance co ntact Bayer CropScience at 1-866-99BAYER (1-866-992-2937). You can also contact your pesticide distributor or university extension specialist to report resistance.

USE RESTRICTIONS x Do not apply OSPREY Xtra Herbicide to crops under sown with grass and legume species. x Do not apply when wind causes drift to off-site vegetation as injury may occur. Small amounts of OSPREY Xtra 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. x Do not apply in combination with Dicamba containing products as grass control will be reduced. x Do not apply OSPREY Xtra Herbicide through any type of irrigation system. x Do not drain or rinse equipment near desirable vegetation. x Do not harvest wheat for grain or straw within 60 days after ap plication in Montana, North Dakota, or South Dakota; and within 70 days in all other states. x Do not apply OSPREY Xtra Herbicide within 30 days of harvesti ng or grazing wheat or triticale forage, and 60 days for hay, grain, and straw. x Do not apply OSPREY Xtra Herbicide in tank mixture with malathion, mancozeb, Di-Syston or methyl parathion as unacceptable crop phytotoxicity may occur. x Only make applications of OSPREY Xtra Herbicide in California from emergence to 2-tiller wheat (Feekes 5). x Do not apply more than 0.053 pounds of mefenpyr-diethyl per acre per year. x Do not make more than one application of OSPREY Xtra Herbicide per year. x Do not apply more than 4.75 oz/acre of OSPREY Xtra Herbicide in one fall sown or winter wheat or fall sown triticale growing season.

Refer to the specific use directions and restrictions in each Crop Subgroup table.

USE PRECAUTIONS x 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. x Applications of ammonium nitrogen fertilizer independent of those made with herbicides are commonly known as top-dress applications. Top-dress 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 Xtra Herbicide application. x Avoid spray drift from treated areas. Refer to the Spray Dr ift section of this label for additional information. x Non-target plants may be adversely affected if the pesticide is allowed to drift from areas of application. To prevent damage to crops and other desirable plants, read and follow all directions and precautions on this label before using. x Environmental conditions which support vigorous growth of crop and weeds also result in highest herbicidal activity. Following application, symptoms of herbicidal activity may develop within several days. Speed of action depends on environmental conditions and increases with increasing temperature and moisture. x Use adjuvants as specified on this label.

APPLICATION INSTRUCTIONS Uniform, thorough spray coverage is important to achieve consistent weed control. The use of nozzles and spray pressure that deliver MEDIUM or coarser spray droplets as indicated in the nozzle manufacturer’s catalogs and in accordance with ANSI/ ASAE Standard S- 572.3 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 section of this label, may result in reduced coverage and weed control.

7

Ground Application OSPREY Xtra 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 Xtra 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 or COARSER spray droplets as indicated in the nozzle manufacturer’s catalogs and in accordance with ANSI/ASABE Standard S641 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 section of this label for additional information on proper application of OSPREY Xtra Herbicide.

MIXING, COMPATIBILITY TESTING AND TANK MIX PARTNERS OSPREY Xtra Herbicide must be applied with clean and properly calibrated equipment. Prior to adding OSPREY Xtra Herbicide to the spray tank, ensure that the spray tank, filters, and nozzles have been thoroughly cleaned.

It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

Compatibility OSPREY Xtra Herbicide is physically and biologically compatible with many registered pesticides and fertilizers or micronutrients. However, there is potential for adverse chemical reactions. It is impossible to determine physical, biological, and plant compatibility for all scenarios that may be encountered; therefore, it is recommended that users determine the chemical, physical, biological and plant compatibility of such mixes prior to making applications on a broad commercial scale.

If OSPREY Xtra Herbicide is to be tank mixed with other products, 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.

Order of Mixing OSPREY Xtra Herbicide may be used with other recommended pesticides, fertilizers, and micronutrients. The proper mixing procedure for OSPREY Xtra Herbicide alone or in tank mix combinations with other pesticides is as follows:

1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of OSPREY Xtra Herbicide.
3. Continue agitation until the OSPREY Xtra Herbicide is fully dispersed, at least 5 minutes.
4. Once OSPREY Xtra Herbicide is fully dispersed, maintain agitation and continue filling tank with water. OSPREY Xtra Herbicide should be fully mixed with water before adding any other material
5. As the tank is filling, add the required amount of spray adju vant and ammonium nitrogen fertilizer. Add additional pesticide tank mix partners, if desired.
6. Continue agitation during herbicide application to ensure unif orm 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.

NOTE: Do not use PVA packets in a tank mix with products that contain boron or release free chlorine. The resultant reaction of PVA and boron or free chlorine is a plastic that is not soluble in water or solvents.

RE-SUSPENDING WG PRODUCTS IN SPRAY SOLUTION Like other Water Dispersible Granules or suspension concentrates (SCs), OSPREY Xtra 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 15 minutes before application.

8

Equipment Cleanup Procedures

1. Drain the tank completely, and then wash out tank , boom and hoses with clean water. Drain again.
2. Half fill the tank 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). Complete filling of 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 and 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.

ROTATIONAL CROP RESTRICTIONS If a crop is not specified in the following table, conduct a field bioassay as described in the FIELD BIOASSAY section.

Crop Rotational Interval Wheat 3 Months Triticale Soybean Rice Bioassay and no less than 3 months Cotton Bioassay and no less than 4 months Peanuts Barley 9 Months

Sunflower Dry Beans Lentils Chickpea Peas Corn Sorghum Sugar Beets 10 Months

Alfalfa Flax Mustard Canary seed Oats, Spring Safflower Timothy Canola Leafy Vegetables Bioassay and no less than 10 months Potatoes 18 Months All Other Crops Bioassay

Field Bioassay / Small Scale Bioassay A field bioassay must be completed before rotating to a crop other than those specified in the “Rotational Crop Restrictions” section of this label. To conduct an effective field bioassay, grow strips of the crop(s) you intend to grow the following season in a field previously treated with Osprey Xtra Herbicide. The test strips should be placed in a controlled area and should include low areas and knolls, and

9

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 Osprey Xtra Herbicide.

WEEDS CONTROLLED & SUPPRESSED OSPREY Xtra Herbicide is a post-emergent herbicide with best results being obtained when applications are made to young actively growing weeds. See weed tables for appropriate application timing and weed size. Treat heavy weed infestations before they become competitive with the crop.

SPECIFIC USE DIRECTIONS

FALL-SOWN OR WINTER WHEAT & FALL-SOWN TRITICALE

Application Rate and Timing Apply OSPREY Xtra Herbicide to fall-sown or winter wheat or fall-sown triticale from emergence up to the jointing stage of growth.

Specific Regional Directions: x In California, apply OSPREY Xtra Herbicide fr om emergence to 2-tiller wheat (Feekes 5). x In Idaho, Oregon, Washington, and Mont ana, OSPREY Xtra Herbicide may be applied from emergence up to the 2-node stage of wheat and fall sown triticale.

Tank Mix Recommendations x OSPREY Xtra Herbicide may be tank mixed with the herbicides listed below to provide broad-spectrum weed control. x When using OSPREY Xtra Herbicide in tank mix combinations, follow the precautions and directions of the most restrictive label. x OSPREY Xtra Herbicide contains 0.091 pounds of mefenpyr-diethyl per pound of product. x Applying the maximum-labeled rate of OSPREY Xtra Herbicide delivers 0.027 lbs of mefenpyr-diethyl per acre. x It is recommended that herbicides not specifically listed on this label for tank mixing with OSPREY Xtra Herbicide be applied sequentially, 5 days prior to or 5 days after an OSPREY Xtra Herbicide treatment. x Abnormally large temperature fluctuations between daytime highs and nighttime lows at the time of application may influence crop tolerance. Frost occurrence the night before or within two days after application may increase crop response. These effects can be quite marked when OSPREY Xtra Herbicide is tank mixed with EC (Emulsifiable Concentrate) partners. Consult with your Bayer CropScience representative for further guidance concerning tank mixes under these conditions. x In Washington, Oregon and Idaho: When tank mixing OSPREY Xtra Herbicide with an EC broadleaf herbicide, reduce the NIS rate from 0.5% to 0.25%. x Refer to the appropriate label of each tank mix partner for in structions regarding application rates required to control weeds not listed on this label.

It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank mixture.

Tank mixes must be used in accordance with the most restrictive label limitations and precautions. 1 Equivalent bromoxynil products may be substituted in a tank mix for these products. 2 Various formulations of MCP Ester/Amine may be tank mixed at manufacturers labeled rates. Follow label restrictions for MCPA application and wheat stage of growth. Increased crop response or reduced grass control may occur when adding MCP amine to OSPREY Xtra Herbicide. 3 Curtail M may be tank mixed at manufacturers labels rates.

Tank Mixtures for Disease Control OSPREY Xtra Herbicide may be applied in combination with Stratego®, Tilt®, Priaxor™, Trivapro®, or Topsin® M 70WP fungicides for weed and disease control. Refer to the specific fungicide label for use directions, application rates, restrictions and a list of diseases controlled.

Tank Mixtures for Insect Control OSPREY Xtra Herbicide may be applied with Baythroid XL, Warrior® Insecticide with Zeon Technology or Z-Cype 0.8 EC Insecticide. Refer to the specific insecticide label for use directions, application rates, restrictions and a list of insects controlled.

Tank Mix Precautions Always follow the label instructions of the tank mix partner as well as OSPREY Xtra Herbicide. Check the compatibility of OSPREY Xtra Herbicide and the tank mix partner by mixing all components in the order specified in the Order of Mixing section, including adjuvants and water, into a small separate container in order to evaluate compatibility prior to adding them to the tank.

Spray Additives OSPREY Xtra Herbicide is a water dispersible granule that does not include an adjuvant. A recommended adjuvant must be tank mixed with OSPREY Xtra Herbicide according to the guidelines as described in the Order of Mixing section.

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 Xtra Herbicide.

Non-ionic Surfactant (NIS) + Ammonium Nitrogen Fertilizer (in water carrier solutions) Use a non-ionic surfactant at a concentration of 0.5% v/v (2 qt per 100 gallons of spray solution) with ammonium nitrogen fertilizer. At least 80% of the surfactant product must be active non-ionic surfactant. Avoid products that do not accurately define their ingredients. Products must contain only EPA-exempt ingredients (40 CFR 1001).

Use a spray grade quality urea ammonium nitrogen fertilizer (20-0-0 to 32-0-0 at 1 – 2 qt/acre) or ammonium sulfate fertilizer (21-0-0-24 at 1.5 – 3 lbs/acre).

Fluid Fertilizer Carrier Solution Applications OSPREY Xtra Herbicide provides consistent performance when applied with water as the spray carrier and a non-ionic surfactant is added to the spray solution. However, OSPREY Xtra Herbicide may be applied using a liquid nitrogen solution (28-0-0 or 30-0-0 or 32-0- 0) as the spray carrier. The fertilizer spray solution should not exceed 15% liquid nitrogen (1.5 gallons of liquid nitrogen in 10 gallons of spray solution per acre). A non-ionic surfactant at a maximum concentration of 0.25% v/v (1 quart per 100 gallons of spray solution) is required in spray solutions containing liquid nitrogen carrier.

Due to the activity of fertilizer on the crop, temporary injury may result when liquid nitrogen is used as a spray carrier. Crop response symptoms due to the use of liquid nitrogen as a spray carrier may include discoloration, and leaf burn.

Fluid Fertilizer Carrier Solution Applications: Washington, Oregon and Idaho Only Apply OSPREY Xtra Herbicide by ground only from emergence up to the second node of crop development in spray solutions containing liquid nitrogen carrier.

Use 3.2 – 4.75 ounces OSPREY Xtra Herbicide /acre by ground in tank mixture with 0.25% v/v non-ionic surfactant up to 3 gallons of liquid nitrogen (20-0-0 to 32-0-0) in a minimum 10-gallon mix per acre.
