What is the purpose of a buffer zone in pesticide application?

The purpose of a buffer zone in pesticide application is primarily to protect sensitive areas from pesticide exposure. A buffer zone refers to an area of land that serves as a protective boundary between the application site and nearby sensitive environments, such as waterways, residential areas, or wildlife habitats. By establishing such zones, applicators can help minimize the risk of pesticide movement off-target, ensuring that non-target plants, animals, and human communities are safeguarded from potential harm due to pesticide drift or runoff. This practice is critical in promoting environmental sustainability and protecting public health.

While the other choices touch upon important aspects of pest management and safety, they do not fully capture the specific role and intent behind buffer zones. For instance, creating a barrier for pest entry or preventing drift can be additional benefits of implementing buffer zones, but the primary rationale centers around protecting sensitive areas from exposure.
