What is the purpose of buffer zones in pesticide applications?

• A. They protect water bodies and sensitive areas by reducing drift into non-target areas.
• B. They help pests reproduce.
• C. They are decorative lines in fields.
• D. They increase drift.

Answer: (A)

Buffer zones are spaces kept around the treated area to protect water bodies and other sensitive sites by reducing spray drift into non-target areas. Drift happens when tiny droplets or vapors move with air and land where you don’t intend them, which can harm aquatic life, pollinators, and people nearby. By maintaining a safe distance and sometimes using vegetative buffers, these zones help keep pesticide applications from reaching streams, ponds, wells, wetlands, or nearby homes. Labels specify how large the buffer must be, and the required distance can change based on the product, formulation, application method, and weather conditions. The other options don’t fit because buffer zones don’t aim to help pests reproduce, aren’t decorative lines, and are designed to decrease drift rather than increase it.
