What is the purpose of the buffer zone around sensitive sites in pesticide applications?

• A. To increase application efficiency
• B. To reduce run-off from the field
• C. To protect people, wildlife, and water resources
• D. To promote faster drying of spray

Answer: (C)

Buffer zones are drift-reduction measures that create a no-spray area around sensitive sites so pesticide moves are kept away from where people, wildlife, and water resources could be affected. This zone helps prevent off-target exposure and contamination, especially near homes, schools, streams, ponds, and wildlife habitats. It’s not about boosting efficiency, speeding drying, or reducing field run-off—it's about protecting people and the environment from pesticide drift.
