Which statement about buffer zones in drift management is true?

• A. Buffer zones shorten application time.
• B. Buffer zones are used to minimize drift to non-target areas.
• C. Buffer zones increase drift.
• D. Buffer zones are only for decorative landscapes.

Answer: (B)

Buffer zones are spaces kept between where the pesticide is applied and nearby non-target areas to reduce drift. The main goal in drift management is to protect people, pets, wildlife, and sensitive sites from off-target pesticide movement through the air. By maintaining a defined gap between the spray zone and these areas, drift exposure is minimized, which is why this statement is true. The required distance for a buffer can vary by product, formulation, application rate, nozzle type, and wind conditions and is specified on the product label.

This approach does not shorten application time and it does not increase drift; in fact, it works to prevent drift. Buffer zones are not only for decorative landscapes; they protect any nearby non-target areas such as homes, gardens, water bodies, beehives, and other sensitive sites.
