What is a no-spray buffer zone?

• A. A time window when spraying is most effective
• B. A buffer zone around water bodies or sensitive areas where spraying is prohibited
• C. A zone where only certain pesticides can be mixed
• D. A test area in the field to check drift

Answer: (D)

A no-spray buffer zone is a protected distance around water bodies and other sensitive areas where pesticide spraying is not allowed. This safety margin helps prevent spray drift from reaching surface water, wells, aquatic habitats, and non-target vegetation, reducing contamination and harm to non-target organisms. The idea is to keep pesticides from moving beyond the treated area.

The option describing a time window for spraying, or a zone for mixing pesticides, or a field test area to check drift, does not fit this concept. Those relate to timing, mixing practices, or drift testing, not to the prohibited-area setback designed to protect nearby water and sensitive sites.
