What is the definition of "pesticide drift"?

The definition of "pesticide drift" refers specifically to the movement of pesticide droplets away from the intended target area during application. This unintentional dispersion can happen due to factors such as wind, temperature inversions, and application methods. Understanding pesticide drift is crucial for ensuring that pesticides do not negatively impact non-target plants, wildlife, or human health. It highlights the need for careful application practices to minimize potential environmental and health risks associated with pesticide use, reinforcing the importance of adherence to safety regulations and best practices in pest management.

The other choices largely focus on aspects of pesticide management that are unrelated to the concept of drift. For instance, methods of applying pesticides effectively or disposing of old pesticides address different concerns entirely, while the cleanup of spills pertains to an emergency response rather than the dynamics of pesticide movement during application.
