0.025 lb/A

Do not apply more than 0.2 lbs ai/acre/year in any treated area.

Apply only when wind speed is greater than or equal to 1 mph.

For ground applications: Spray equipment must be adjusted so that the 

volume median diameter is less than 30 microns (Dv 0.5 < 30 μm) and 

that 90% of the spray is contained in droplets smaller than 50 microns 

(Dv 0.9 < 50 μm).

For aerial applications: Spray equipment must be adjusted so that the 

volume median diameter produced is less than 60 microns (Dv 0.5 < 60 

μm) and that 90% of the spray is contained in droplets smaller than 80 

microns (Dv 0.9 < 80 μm). 

Apply using a nozzle height of no less than 100 feet above the ground or 

canopy for aerial applications with fixed wing equipment. 

Apply using a nozzle height of no less than 75 feet above the ground or 

canopy for aerial applications with rotary wing equipment.
