Why are buffer zones near water important in pesticide applications?

• A. To protect spray tanks from contamination.
• B. To increase evaporation.
• C. To require more concentrate.
• D. To protect water quality and non-target organisms.

Answer: (D)

Buffer zones protect water quality and non-target organisms by reducing the movement of pesticides toward water bodies. By keeping a safe distance between where pesticides are applied and streams, rivers, ponds, and wetlands, these zones limit spray drift during application and curb runoff after rain or irrigation. This helps prevent contamination of surface water and groundwater, safeguarding drinking water supplies and protecting aquatic life such as fish, amphibians, and aquatic insects, as well as other organisms that rely on those habitats. It’s about environmental protection and regulatory compliance, not about equipment, evaporation, or using more product.
