Spray drift is a major concern with the use of mist blowers.

• A. True
• B. False
• C. Only under high wind
• D. It is never a concern

Answer: (A)

Mist blowers move a large airstream to create a fine spray, so droplets can be carried far from the target. That makes spray drift a major concern with these devices. The combination of small droplet size and strong air movement means droplets don’t settle quickly and can travel downwind to non-target areas, risking impacts on nearby crops, ornamentals, water sources, or people. Drift risk rises with finer droplets, higher spray pressure, greater boom height, and wind or turbulent air conditions, so drift can occur even at modest winds or in unstable air. To minimize drift, use coarser droplets when possible, lower spray pressure and speed, keep the nozzle and sprayer as low as feasible and aimed at the target, and spray only under suitable weather conditions while following drift-reduction practices.
