What defines drift in pesticide application?

Drift in pesticide application refers specifically to the unintended off-target movement of pesticides through the air. This phenomenon can occur when pesticides are applied as sprays and are carried away from the intended application site due to various factors such as wind, temperature inversions, or spray droplet size. This movement is problematic as it can lead to pesticide exposure to non-target organisms, including neighboring crops, wildlife, and even human populations.

Understanding drift is crucial for both environmental safety and regulatory compliance. Effective drift management strategies are often implemented to minimize these risks, ensuring that pesticides only affect the areas they are intended to treat. Recognizing drift allows applicators to assess the potential impact of their applications and adjust methods accordingly to mitigate off-target effects.
