What role do buffers play in pesticide application?

Buffers play a critical role in pesticide application by serving as designated areas where no pesticides are applied. These buffer zones are established to protect sensitive environments, such as water bodies, wildlife habitats, and residential areas, from potential pesticide drift and contamination. By ensuring that pesticides are not applied in these areas, the risk of harming non-target organisms and ecosystems is significantly reduced. This practice is essential for promoting environmental stewardship and adhering to regulations designed to safeguard public health and natural resources.

In contrast, the other options do not accurately represent the function of buffers in pesticide application, as they do not pertain to the protective measures needed to mitigate environmental impact. Buffers are not used to enhance efficiency or regulate pesticide usage in a direct manner or to neutralize pesticides. Their primary purpose is to provide a safeguard against unintended pesticide exposure in vulnerable areas.
