What are field buffers, and why are they used?

Field buffers are designated zones that are intentionally left free of pesticide applications to protect sensitive areas from potential pesticide drift or runoff. These buffers are critical in minimizing the impact of agricultural chemicals on non-target organisms and environments that could be affected by pesticide exposure. Sensitive sites might include water bodies, wildlife habitats, or human habitations, where the presence of pesticides could harm health or ecological systems.

By establishing these buffer zones, aerial applicators help ensure compliance with environmental regulations and maintain the integrity of surrounding ecosystems. This practice is part of an integrated pest management strategy, combining effective pest control while minimizing environmental risks. Using appropriate buffer zones can help maintain biodiversity and support sustainability in agricultural practices.

The other options involve concepts that do not accurately describe field buffers; they either suggest inappropriate applications or practices unrelated to the protective function of field buffers.
