Gramoxone® Max INSTRUCTIONSGENERAL •R • Do not apply this product through any type of irrigation system. When Gramoxone Max is applied at less than 10 gallons per acre finished spray volume, a drift control or spray deposition additive SHOULD be used. Refer to the additive label for use directions. Spray Drift Information 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. 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 appli- cations, public health uses or to applications using dry formulations. 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°. 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. Aerial Drift Reduction Advisory Information (This section is advisory in nature and does not supersede the mandatory label requirements.) 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. • 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 uniess a greater height is required for aircraft safety. Making application 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 d ry.
