What term describes the movement of a pesticide away from the application area?

• A. Off-target movement
• B. Drift
• C. Runoff
• D. Leaching

Answer: (A)

Movement of a pesticide away from the application area is called off-target movement. This broad term covers any pesticide leaving the intended zone, no matter the pathway. A common form is drift, where droplets or spray are carried by air currents during or just after application. Runoff means pesticide moves with surface water away from the treated area, while leaching is movement down through the soil toward groundwater. Recognizing off-target movement helps explain why proper application practices, weather considerations, and buffer zones are important to protect surrounding areas.
