Washington Agricultural and Right-of-Way Pesticide Practice Test

Buffer zones are designated areas around the site of pesticide application that serve the critical function of minimizing pesticide exposure to sensitive areas, such as waterways, residential zones, or habitats for wildlife. By establishing these zones, applicators help to reduce the risk of pesticide drift and runoff, ensuring that non-target organisms and ecosystems are protected from potential harm. This protection is vital for maintaining environmental health and safeguarding biodiversity.

In contrast, while increasing pesticide effectiveness and enhancing pest resistance might pertain to the broader goals of pest management, they do not directly address the primary function of buffer zones. These zones are not designed to improve the economic viability of pesticide applications either; their primary purpose focuses on environmental safety and regulatory compliance. Thus, the correct choice underscores the importance of safeguarding sensitive areas during pesticide applications.
