Which statement is true about pesticide drift risk with hydraulic sprayers?

• A. They are more likely than smaller sprayers to cause pesticide drift
• B. They never drift
• C. They always drift in all conditions
• D. Drift is not a concern with hydraulic sprayers

Answer: (A)

Pesticide drift occurs when droplets move off the target area due to air movement, and the size of the droplets is the main factor. Hydraulic sprayers push liquid through nozzles at high pressure, and depending on the nozzle design and settings, they can produce finer droplets. Fine droplets are more easily carried by breezes and can travel farther than larger droplets, so drift risk is higher with hydraulic systems than with some smaller sprayers that tend to produce coarser droplets or operate at settings that create larger droplets. This risk isn’t absolute—drift can still be minimized with proper nozzle selection for coarse droplets, lower application pressure, keeping the boom as low as practical, avoiding windy conditions, and applying drift-reduction practices. The other statements aren’t correct because drift can and does occur under many conditions, and it’s not accurate to say it never happens, always happens, or that drift isn’t a concern.
