Reduce chances of drift by spraying when the wind speed is ______.

Reduce chances of drift by spraying when the wind speed is ______.

• A. Completely calm
• B. 1 to 2 mph
• C. Greater than 10 mph
• D. 3 to 10 mph

Answer: (D)

Reducing drift relies on wind speed: a moderate breeze helps droplets reach the target while limiting how far they travel off-target. If it’s completely calm, small droplets can be moved unpredictably by local air currents and temperature effects, increasing off-target deposition. If the wind is too strong, droplets are carried far beyond the target area. The best balance is a wind speed in the 3 to 10 mph range, which pushes droplets toward the target without causing large-scale off-target drift.
