Which action helps prevent drift during pesticide application?

• A. Proceed in a direction into the wind to prevent working in drift
• B. Apply during gusty winds
• C. Use a high drift nozzle
• D. Apply when fully overcast

Answer: (A)

Droplet drift is all about how air moves the spray after you release it. The goal is to have the wind help push the droplets toward the target and away from non-target areas, rather than letting them blow off to the sides or back toward you and nearby sites. Proceeding in a direction into the wind places the spray in the path of the air flow so the wind carries the droplets toward the target downwind, reducing the chance they move off-target. Gusty winds create turbulence and unpredictable droplet movement, which increases the likelihood of off-target deposition. A nozzle that produces very fine droplets also drifts more easily with the wind, raising drift risk. Applying when conditions are overcast doesn’t directly prevent drift, since cloud cover doesn’t guarantee calm, stable air; drift is more about wind speed and stability than light or darkness. So, the action that helps prevent drift is aligning your spray path with the wind in a way that directs droplets toward the target, while avoiding gusty winds and using appropriate nozzle settings to keep droplets from drifting off-target.
