PRODUCT INFORMATION RIMFIRE® Max Herbicide is intended for application as a foliar spray in winter and spring wheat (including durum) for control of annual grasses and broadleaf weeds. ENVIRONMENTAL AND BIOLOGICAL ACTIVITY RIMFIRE Max Herbicide is absorbed by foliage and roots of weeds and offers contact and residual weed control. RIMFIRE Max Herbicide provides the most consistent control when applied to actively growing weeds. RIMFIRE Max Herbicide is active against many important grass and broadleaf weeds (see list below for details). 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 herbicide action depends on environmental conditions and increases with increasing temperature and moisture. Sensitive weeds quickly stop growing and no longer compete with the crop. Visible signs of activity include cessation of elongation, yellowing and/or reddening of weeds, and finally plant death. Abnormal environmental conditions (excess soil moisture or drought, extreme cold weather) can influence crop tolerance and herbicidal activity and may cause temporary response of the crop or reduced 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 an application of RIMFIRE Max Herbicide to actively growing wheat. CROPS RIMFIRE Max Herbicide may be used on winter and spring wheat, including durum. SURFACTANTS RIMFIRE Max Herbicide is a water dispersible granule that does not include an adjuvant. A recommended adjuvant must be tankmixed with RIMFIRE Max Herbicide according to the guidelines as described in the MIXING INSTRUCTIONS section. RIMFIRE Max Herbicide offers the flexibility to choose between three distinct adjuvant systems including 1) methylated seed oil or 2) “basic blend” type adjuvant, 3) non-ionic surfactant plus ammonium nitrogen fertilizer. A methylated seed oil, basic blend adjuvant or a non-ionic surfactant (NIS) plus ammonium nitrogen fertilizer must be tankmixed with RIMFIRE Max Herbicide. 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 RIMFIRE Max Herbicide.

1. Methylated Seed Oil (MSO) A methylated seed oil offers the most robust adjuvancy with RIMFIRE Max Herbicide. Select a high quality methylated seed oil containing at least 80% methylated seed oil and 10% emulsifier or greater. Use 1.3 – 1.5 pt MSO/acre in tankmixture with RIMFIRE Max Herbicide. The potential for crop response may be increased with the use of MSO compared to non-ionic surfactant plus ammonium nitrogen fertilizer. When a methylated seed oil is used, ammonium nitrogen or ammonium sulfate fertilizers are not recommended.

5 141 mm 145 mm 130 mm 120 mm 22 5 4 2) Basic Blend Adjuvants A basic blend adjuvant is a formulated combination of a non-ionic surfactant or methylated seed oil and a nitrogen source. Apply a basic blend adjuvant at 1 - 1.25 % v/v in tank mixture with RIMFIRE Max Herbicide. Select the appropriate amount of basic blend adjuvant per acre depending on local conditions but do not apply less basic blend adjuvant than 0.8 pt/acre. When a basic blend adjuvant is used, ammonium nitrogen or ammonium sulfate fertilizers are not recommended. 3) Non-ionic Surfactant (NIS) + Ammonium Nitrogen Fertilizer (in water carrier solutions) Use a non-ionic surfactant at a concentration of 0.25 - 0.5% v/v (1-2 qts 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. Use a spray grade quality urea ammonium nitrogen fertilizer (28-0-0 or 30-0-0 or 32- 0-0 at 1 – 2 qt/acre) or ammonium sulfate fertilizer (21-0-0-24 at 1.5 – 3 lbs/acre). APPLICATION INFORMATION RIMFIRE Max Herbicide should be applied to actively growing wheat in the spring. RIMFIRE Max Herbicide provides consistent performance when applied with water as the spray carrier and the appropriate additive is added to the spray solution. Properly calibrated ground or aerial (fixed wing or helicopter) application equipment may be used to apply RIMFIRE Max Herbicide postemergence as a foliar spray. Weed infestations should be treated before they become competitive with the crop. Thorough coverage of weeds is necessary to obtain good 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. Select spray nozzles that provide best spray distribution and weed coverage at the appropriate spray pressure. Avoid uneven spray distribution, skips, overlaps, and spray drift. Do not apply RIMFIRE Max Herbicide through any type of irrigation system. Apply 3 ounces/acre of RIMFIRE Max Herbicide to wheat from emergence (fully expanded first true leaf) up to flag leaf emergence. Do not apply more than a total of 3 ounces/acre of RIMFIRE Max Herbicide per season. GROUND APPLICATION RIMFIRE Max 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. To get uniform spray coverage, use nozzles and pressure that deliver MEDIUM spray droplets as indicated in nozzle manufacturer’s catalogs and in accordance with ASAE standard S-572. Use screens that are 50 mesh or larger. Ground speed for application should not exceed 10 mph. AERIAL APPLICATION Calibrate the spray equipment prior to use. RIMFIRE Max Herbicide should be applied in a minimum of 5 gallons of water per broadcast acre. Weed infestations should be treated before they become competitive with the crop. To get uniform spray coverage, use nozzles and pressure that deliver MEDIUM spray droplets as indicated in nozzle manufacturer’s catalogs and in accordance with ASAE standard S-572. DO NOT use raindrop nozzles. (continued)

5 141 mm 145 mm 130 mm 120 mm 22 5 5 Aerial applications with this product should be made at a maximum height of 10 feet above the crop with low drift nozzles. 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 RIMFIRE Max Herbicide. MIXING INSTRUCTIONS RIMFIRE Max Herbicide must be applied with clean and properly calibrated equipment. Prior to adding RIMFIRE Max Herbicide to the spray tank, ensure that the spray tank, filters and nozzles have been thoroughly cleaned. In-line strainers and nozzle screens should be 50 mesh or coarser.

1. Fill the spray tank 1/4 to 1/2 full with clean water and begin agitation or bypass.
2. Add the appropriate rate of RIMFIRE Max Herbicide, as determined under “Recommended Rates,” directly to the spray tank. Maintain sufficient agitation during both mixing and application.
3. Add a recommended broadleaf weed herbicide, if desired.
4. Add the surfactant.
5. Fill the spray tank with balance of water needed.
6. Continue agitation during RIMFIRE Max Herbicide application to ensure uniform spray coverage. If the mixture is not continuously agitated, settling may occur. Use spray solution within 24 hours after mixing. RE-SUSPENDING WDG PRODUCTS IN SPRAY SOLUTION Like other Water Dispersible Granules or suspension concentrates (SC’s), RIMFIRE Max Herbicide may 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. COMPATIBILITY If RIMFIRE Max 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 quart) 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. Indications of incompatibility include separation in the mix and either clumping or clabbering of the mixture. Read and follow the label of each tank mix product used for precautionary statements, directions for use, geographic and other restrictions.

5 141 mm 145 mm 130 mm 120 mm 22 5 8 TANK CLEANUP PROCEDURE

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. CROP ROTATION RESTRICTIONS To ensure safety of rotational crops, the following rotational intervals must be followed: North Dakota & Minnesota, Montana & South Dakota Washington, Oregon & Idaho

Crop Rotation Interval (Months)

Crop Rotation Interval (Months) Wheat 0 Wheat 0 Millet 4 Millet 4 Alfalfa 10 Alfalfa 10 Barley 10 Barley 10 Canola 10 Canola 12 Corn-conventional 10 Dry Beans 10 Dry Beans 10 Lentils 10 Flax 10 Peas 10 Lentils 10 Corn-Conventional 18 Peas 10 Safflower 10 Soybeans 10 Sugar Beets 10 Sunflowers 10 • In areas where a crop is not specified, conduct a field bioassay as described in the FIELD BIOASSAY section of this label. • In all areas, 24 inches of precipitation and a 12-month rotation interval are required for potatoes, buckwheat, and onions. Rotational crops should not be planted on clay or eroded knolls or hillsides following a RIMFIRE Max Herbicide application without conducting a field bioassay.

5 141 mm 145 mm 130 mm 120 mm 22 5 9 FIELD BIOASSAY A field bioassay must be conducted for crops not listed on this label and for crops listed on the label for which a shorter plant-back interval than listed is desired. To conduct a field bioassay, plant strips of the crop you want to grow the season following RIMFIRE Max Herbicide application. Monitor the crop for response to RIMFIRE Max Herbicide to determine if the crop can be grown safely in previously treated RIMFIRE Max Herbicide areas. Regardless of the bioassay results, do not plant any crop, except fall-sown or winter wheat, closer than 4 months after a RIMFIRE Max Herbicide application. WEED RESISTANCE Mode of Action The active ingredients in this product, mesosulfuron-methyl, and propoxycarbazone-sodium are Group 2 Herbicides based on the mode of action classification system of the Weed Science Society of America. Any weed population may contain plants naturally resistant to Group 2 herbicides. Weeds resistant to Group 2 herbicides may be effectively managed utilizing another herbicide from a different Group and/or by using cultural or mechanical practices. However, a herbicide mode of action classification by itself may not adequately address specific weeds that are resistant to specific herbicides. Consult your local company representative, state cooperative extension service, professional consultants, or other qualified authorities to determine appropriate actions for treating specific resistant weeds. Best Management Practices RIMFIRE Max Herbicide is an acetolactate synthase (ALS) inhibiting herbicide. Repeated use of herbicides with the same mode of action allows resistant weeds to spread. Proactively implementing diversified weed management programs may delay the development of resistant weeds. Diversified programs include the use of multiple herbicides with different modes of action with overlapping weed spectrums as well as the utilization of cultural weed control practices, such as tillage. • Use labeled rates of herbicides and carefully follow the directions for use • Scout fields after a herbicide application to facilitate early detection of weed shifts and/or weed resistance • Implement measures to avoid allowing weeds to reproduce by seed or proliferate vegetatively • Clean equipment between sites and avoid movement of plant material between sites to retard the spread of potentially resistant weed seed. The use of RIMFIRE Max Herbicide should conform to resistance management strategies established for the use area. Consult your agricultural advisor for resistance management strategies and recommended pest management practices for your area. SPRAY DRIFT MANAGEMENT RIMFIRE Max 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. SENSITIVE AREAS: The pesticide must 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 and grower. 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. (continued)

5 141 mm 145 mm 130 mm 120 mm 22 5 10 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. The following drift management requirements must be followed to avoid off-target drift movement 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 shall 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 on next page). 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 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.

5 141 mm 145 mm 130 mm 120 mm 22 5 11 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 aircraft 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. 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 because drift potential is high. 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. ENDANGERED SPECIES To avoid adverse effects on endangered plant species, the following mitigation measures will be required where endangered species occur in Counties listed in the table on the following page. For ground applications, the applicator must:

1. Apply when there is sustained wind away from native plant communities, OR
2. Leave 50 foot untreated buffer between treatment area and native plant communities. For aerial applications, the applicator must:
