Spray drift is the physical movement of a pesticide through air at the time of application, or soon thereafter, to any site other than that intended for application (often referred to as off-target). Consider these best management practices for managing spray drift: pay attention to wind speed and direction; plan to spray when wind is blowing away from sensitive areas; select proper nozzle size and type with correct pressure to manage desired spray droplet size; keep spray boom as low as possible; factor for relative humidity and air temperature; use a drift control adjuvant. You cannot totally control drift. KALO has products that significantly reduce the number of driftable fines in the spray pattern to help manage drift to acceptable limits. Drift mitigation or drift management are more accurate terms than drift control.
