What does “drift” refer to in the context of pesticide application?

In the context of pesticide application, "drift" specifically refers to the unintended movement of pesticides away from the target area where they were applied. This phenomenon can occur due to factors such as wind, temperature inversions, or improper application techniques. Understanding drift is crucial for maintaining effective pest control while also protecting non-target organisms, including beneficial insects, plants, and nearby ecosystems. Effective management of drift is essential for compliance with regulations and to minimize environmental impacts.

The other options relate to different aspects of pesticide use but do not encapsulate the definition of drift. Target efficacy pertains to how well the pesticide performs against its intended pest, mixing is about preparing the pesticide for application, and absorption rate concerns how quickly and effectively plants take up the pesticide. None of these options accurately capture the meaning of drift in pesticide application.
