What is meant by pesticide drift?

Pesticide drift refers specifically to the unintended movement of pesticide products onto non-target areas, primarily as a result of air currents. This phenomenon can occur when pesticides are applied through aerial spraying, ground equipment, or other methods, where wind or temperature inversions carry the pesticide beyond the intended treatment area. This unintentional dispersal can lead to negative impacts on surrounding plants, wildlife, and humans, making it a critical issue for applicators and regulators alike.

Understanding pesticide drift is crucial for implementing best management practices in pest control to mitigate risks associated with off-target contamination. By being aware of factors that influence drift, such as weather conditions and application techniques, pest control professionals can take steps to minimize potential harm to adjacent environments and organisms.
