PRODUCT INFORMATION Pulsar Herbicide is a postemergence, systemic herbicide for the control of broadleaf weeds in all varieties of spring wheat (including durum), winter wheat, and barley. The active ingredients in Pulsar Herbicide are readily absorbed by leaves and stems and translocate systemically in target weeds, accumulating in areas of active growth. Pulsar Herbicide controls weeds by interfering with the plant's growth hormones (auxins) causing the disruption of normal plant growth patterns. Symptoms include twfs1inga7id^wling^^ chlorosis (yellowing), growth inhibition and eventual plant death. Level and rate of control depend on weed species, growing conditions, crop competition, and coverage. Thorough spray coverage of target weeds is essential for consistent control. Restrictions and Precautions • Do not apply on or near desirable trees or plants or in locations where chemical may be washed into contact with their roots. • Do not apply adjacent to sensitive crops when the temperature on the day of application is expected to exceed 85°F as drift is more likely to occur. • Do not spray if conditions of thermal inversion exist, or if wind direction and speed may cause spray to drift onto adjacent nontarget areas. Drift minimization is the responsibility of the applicator. Consult with local and State agricultural authorities for information on avoiding or minimizing spray drift. • Avoid overlapping spray swath as crop injury may occur. • Do not apply when wind velocity exceeds 15 mph. • To avoid subsequent injury to other crops, thoroughly clean application equipment immediately after spraying. Ensure that all traces of the product are removed. See section on cleaning spray equipment.

Pulsar Herbicide Page 7 • Do not use if wheat or barley is underseeded with a legume. Management of Resistant Weeds Pulsar Herbicide contains Group 4 (synthetic auxins) herbicides. Some naturally occurring weed populations have been identified as resistant to Group 4 herbicides. Selection of resistant biotypes, through repeated use of these herbicides in the same field, may result in control failures. A resistant biotype may be present if poor performance cannot be attributed to adverse weather conditions or improper application methods. If resistance is suspected, contact your local Syngenta representative for assistance. The following practices will'delay selection for resistant populations of weeds: • Apply postemergence herbicides to small, actively growing weeds. • Ensure that good spray coverage is achieved with proper spray volumes and calibrated equipment. • Use the full label rate of product. • Avoid tank mixes that may cause antagonism and reduced weed control. • Where possible, avoid the repeated use of herbicides with the same mode of action (i.e., same group number) in successive seasons either in cereal crops or rotational crops. • Use a diverse crop/fallow rotation to extend the range of available herbicides and agronomic practices. • Use cultivation, fertilizer regimens, seeding rates and row widths that enhance crop competitiveness. • Prevent weed escapes from producing seed either in the crop or during fallow periods. Crop Rotation Intervals The following crops may be planted at the specified interval following application of Pulsar Herbicide.

Precaution: Do not apply to a crop that is stressed by conditions such as frost, low fertility, drought, flooding, disease damage, or insect damage as crop injury may result. For optimum results, apply Pulsar Herbicide to actively growing weeds. An early . application will maximize crop yields by reducing weed competition. Weed control , following application of Pulsar alone or in combination with other herbicides can be reduced or delayed under conditions of stress such as drought, heat, insufficient fertility, flooding, and prolonged cool temperatures. Optimum weed control will be obtained if application of Pulsar Herbicide is delayed until the conditions of stress have ended and weeds are once again actively growing. Weeds emerging after Pulsar Herbicide application will not be controlled. Rainfastness Rain or irrigation occurring within 4 hours after application may reduce the efficacy of Pulsar Herbicide.

Pulsar Herbicide Page 9 GROUND AND AERIAL APPLICATION PROCEDURES For best accuracy, calibrate the sprayer before use. Ground Applications Water Volume - Use a minimum of 8 gallons of water per acre. r Spray Nozzles - 80° or 110° flat fan nozzles are recommended for optimum spray coverage. Nozzles must be uniformly spaced along the boom to provide accurate and uniform coverage. Point the nozzles forward in the direction of travel at an angle of 45° for optimum coverage of weeds. Follow the nozzle manufacturer's recommendations for pressure and screens. Do not use flood or hollow cone type nozzles. Screens - Use a screen or strainer with 16-mesh or coarser on the suction side of the pump. Do not place a screen in the recirculation line unless using a roller or piston pump. Use 50-mesh or coarser screens between the pump and boom and at the nozzles. Pressure - 35-40 psi at the nozzles. Lower pressure may be used with extended range or low pressure nozzles. Pump - Must have capacity to maintain pressure (35-40 psi) and to maintain the product suspension through tank agitation. A centrifugal pump is recommended with an agitation rate of 20 gal/minute/100 gal tank size. Agitation must be maintained during mixing and spraying. , Good weed coverage with the spray mixture is essential for optimum weed control results. Observe sprayer nozzles frequently during the spraying operation to ensure that the spray pattern is uniform. Avoid large spray overlaps which result in excessive rates in the overlap areas. Also, avoid application under conditions when uniform coverage cannot be obtained or when excessive spray drift may occur. To reduce spray drift, do not apply under windy conditions. Allow adequate distance between target area and desirable vegetation to prevent drift to nontarget areas. Boom height for broadcast over-the-top application should be based upon the free-standing height of the crop, not height above the soil surface, and should be at least 12 inches above the crop. Aerial Applications Apply Pulsar Herbicide in water using a minimum spray volume of 3 gal/A. Avoid application under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. Make applications at a maximum height of 10 ft above the crop with low-drift nozzles at a maximum pressure of 40 psi and wind speed not exceeding 10 mph to help assure accurate application within the target area.

Pulsar Herbicide Page 10 Drift Management Avoiding spray drift at the application site is the responsibility of the applicator and the grower. The interaction of many equipment- and weather-related factors determines the potential for spray drift. The applicator and grower must consider the interaction of equipment and related factors to ensure that the potential for drift to sensitive non-target plants is minimal. The following drift management requirements must be followed to avoid off-target drift movement from aerial applications to agricultural field crops. These requirements do not apply to forestry applications, public health uses, or to applications using dry formulations.

1. The distance of the outermost nozzles on the boom must not exceed % the length of the wingspan or rotor.
2. Nozzles must always point backward parallel with the air stream and never be pointed downward more than 45 degrees. Where states have more stringent regulations, they must be observed. The applicator should be familiar with and take into account the information covered in the Aerial Drift Reduction Advisory Information. 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)./ 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.

Pulsar Herbicide Page 11 • 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 % 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 ft 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. 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.). 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. 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. Temperature Inversions Applications should not occur during a temperature inversion because drift potential is high. Temperature inversions restrict vertical air mixing, which causes small suspended

r r v Pulsar Herbicide Page 12 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. Sensitive Areas This pesticide may only be applied when the potential for drift to adjacent sensitive areas, e.g., residential areas, bodies of water, non-target plants is minimal, (i.e., when the wind is blowing away from the sensitive area.) Avoid all direct or indirect contact (such as spray drift) of Pulsar Herbicide with crops other than those specified for treatment on this label since injury may occur. Chemigation Do not apply this product through any type of irrigation system. SPRAY ADJUVANTS Nonionic surfactant (NIS) may be added to the spray mixture. Use NIS containing at least 80% active ingredient at 0.125-0.25% v/v (1-2 pints/100 gallons) of finished spray volume. Use of NIS can improve control under less than optimum environmental conditions such as dry growing conditions, low relative humidity or cool temperatures. Npte: When Pulsar Herbicide is tank mixed with herbicides that have a built-in adjuvant, no additional NIS is recommended. USE RATE Apply Pulsar Herbicide at 8.3-12.5 fl oz/A. WEEDS CONTROLLED Pulsar Herbicide can be applied alone or tank mixed with MCPA ester for broad- spectrum control of broadleaf weeds.
