Which statement best describes the relationship between buffer zones and off-site movement?

• A. Buffer zones have no effect on movement
• B. Buffer zones reduce off-site movement of pesticides.
• C. Buffer zones increase off-site movement
• D. Buffer zones only affect on-site activities

Answer: (B)

Buffer zones are safety margins around where pesticides are applied, designed to keep drift and runoff from leaving the treated area. They reduce off-site movement by providing distance and often vegetation or barriers that absorb, trap, or slow down pesticides as they move away from the target field. This means lower concentrations reach off-site areas like nearby water bodies, wells, or neighboring property, helping protect people and environmental resources. So, the best description is that buffer zones reduce off-site movement of pesticides. They don’t have no effect, they don’t increase movement, and they aren’t only about on-site activities—their primary purpose is to limit what moves off the treated area.
