What is drift in pesticide application?

Drift in pesticide application refers to the movement of pesticide particles to unintended areas, often as a result of wind or other environmental factors during or after the application process. This is a significant concern because it can lead to unintended exposure of non-target organisms, including beneficial insects, wildlife, and humans, as well as contamination of water sources and nearby crops. Understanding drift is critical for applicators to minimize environmental impact and ensure compliance with safety regulations.

The other concepts listed do not accurately describe drift. For instance, splatter on the ground pertains to direct application and does not involve unintentional movement. The trade of pesticides between applicators is a logistical issue unrelated to application techniques or environmental effects. Accumulation of pesticide residue over time refers to residue build-up in soil or surfaces, which, while important, does not reflect the immediate dynamics involved in drifting during application.
