What does the term "drift" refer to in aerial applications?

The term "drift" specifically refers to the unintended movement of pesticide sprays away from the targeted application area, primarily influenced by wind or air movement. In aerial applications, it is crucial to minimize drift because pesticides that are carried off target can harm non-target organisms, contaminate water sources, and reduce the effectiveness of the application by not reaching the desired area.

Understanding drift is essential for effective and responsible pesticide application, as it helps operators develop strategies to mitigate risks associated with drift, such as selecting appropriate nozzles, adjusting flight patterns, or modifying flight speeds when wind conditions are present. This consideration ensures that pesticide application adheres to regulatory standards and promotes environmental stewardship.
