Illinois Turf Pesticide Practice Test

What is the function of a buffer zone in turf pesticide applications?

To provide space for equipment and safe access To protect water bodies, non-target organisms, and sensitive areas from drift and runoff To measure spray distribution To determine field boundaries

Correct Answer:

To protect water bodies, non-target organisms, and sensitive areas from drift and runoff

Explanation:

Buffer zones are protective setbacks that keep pesticide movement from the treated area to surrounding places. They reduce spray drift and runoff so that water bodies, non-target organisms, and sensitive areas aren’t exposed to the chemicals. When pesticides are applied, droplets can drift with the wind or be carried by rainwater, so a buffer zone acts as a safeguard a short distance around fields. This function is built into labels and regulations because protecting water quality and nearby ecosystems is a key goal of responsible turf pesticide use. The other options describe operational space, measuring spray, or marking field edges, which aren’t the purpose of a buffer zone.
