What should be done to minimize spray drift during applications?

• A. Increase flight speed to reduce exposure time.
• B. Dispense at maximum pressure.
• C. Use appropriate nozzle types, maintain proper height, and consult pesticide labels for recommendations.
• D. Use any nozzle as long as it’s clean.

Answer: (C)

Drift is minimized by controlling how droplets behave once they’re released, which means choosing the right nozzle, keeping the spray at the proper height above the target, and strictly following the pesticide label for drift guidance. The right nozzle type helps produce droplets of a size that will deposit on the target rather than drift away; staying at an appropriate height reduces the distance droplets travel before reaching the target and lowers their exposure to air currents that push them off course. The pesticide label provides product-specific drift management directions, including recommended nozzle types, acceptable pressures, and any adjuvants or weather conditions to consider, ensuring the application stays within safe and effective limits.

Increasing flight speed doesn’t reliably reduce drift and can increase turbulence or create other issues. Dispensing at maximum pressure tends to produce finer droplets that drift more easily. Using any nozzle as long as it’s clean ignores essential drift-control factors like droplet size and label guidance.
