What is the importance of buffer zones in aerial application?

Buffer zones are crucial in aerial application practices primarily to protect non-target areas from pesticide exposure. When pesticides are applied from the air, there is always a potential risk of drift, where the pesticide particles can move away from the intended target area due to wind or other environmental factors. A well-defined buffer zone acts as a safeguard to minimize the risk of pesticide drift reaching sensitive environments, such as residential areas, water bodies, and habitats for wildlife. By implementing these buffer zones, applicators help to maintain environmental integrity and ensure the safety of people, animals, and beneficial organisms that could be adversely affected by unintended pesticide contact.

While enhancing pesticide efficacy, facilitating easier aerial navigation, and increasing application efficiency might be important considerations in aerial application, they do not address the primary purpose of establishing buffer zones, which is fundamentally rooted in environmental protection and safety.
