What is the purpose of buffer zones near water and stormwater pathways?

• A. To minimize drift and prevent pesticides from entering water bodies, protecting aquatic ecosystems.
• B. To enhance fragrance.
• C. They are optional and rarely used.
• D. They decrease efficacy.

Answer: (A)

Buffer zones near water and stormwater pathways exist to keep pesticides from reaching water bodies. They create a protective strip of vegetation and space between where pesticides are applied and nearby streams, ponds, or drainage channels. This setup reduces spray drift, which are tiny droplets blown off-target by wind, and intercepts runoff or leaching during rain, helping prevent contamination of aquatic habitats. Protecting water quality also aligns with pesticide label directions and environmental regulations, supporting sustainable pest management. These zones are standard practice and are not intended to enhance fragrance, and they aren’t optional or designed to reduce effectiveness; when used properly, they help maintain both environmental health and effective pest control.
