What is meant by "pesticide drift"?

The term "pesticide drift" refers specifically to the movement of pesticide spray or vapors away from the area where it was originally applied. This phenomenon can occur due to various factors such as wind, temperature, and application method, leading to unintentional exposure of non-target plants, animals, or even humans. Understanding pesticide drift is crucial for ensuring environmental safety and effective pest control, as it highlights the need for careful application practices to minimize unintended consequences.

Other options do not accurately describe pesticide drift. The sinking of chemical products, intentional dissemination over crops, and the increase of pesticide concentration in one area all refer to different processes that do not capture the essence of drift, which is the unintended movement away from the application site.
