Drift occurs when the pesticide moves off target even if applied correctly. True or false?

• A. True
• B. False
• C. Sometimes
• D. Never

Answer: (A)

Drift is the off-target movement of pesticide droplets during application due to how air moves and how droplets behave. Even when you set up the equipment correctly and follow the label, conditions like wind gusts, temperature inversions, and nearby air currents can carry fine droplets away from the target area. The size of the droplets matters a lot—smaller, finer droplets are much more prone to being blown off course than larger ones. While you can minimize drift by choosing appropriate nozzles, adjusting boom height, controlling spray pressure, and scheduling around favorable weather, you can’t guarantee zero drift in all situations. So the statement is true.
