What is the purpose of drift-reducing nozzles in outdoor pesticide applications?

• A. To increase drift toward non-target areas.
• B. To reduce coverage uniformity.
• C. To minimize off-target drift and protect non-target areas.
• D. To simplify application by avoiding calibration.

Answer: (C)

Drift-reducing nozzles are designed to keep more of the pesticide where you intend it. They achieve this by creating larger droplets and reducing spray velocity, which lowers the likelihood that droplets will be carried by wind or air currents away from the target. The result is less off-target movement and better protection for nearby non-target areas such as bystander sites, non-target plants, water bodies, and wildlife. This approach improves the efficiency of the application by concentrating more of the spray on the crop or target surface.

It's also important to pair drift-reducing nozzles with proper technique—correct spray height, appropriate wind conditions, and choosing the right nozzle type for the product—to maximize drift control. Calibration remains necessary to ensure the chosen nozzle and settings deliver the intended rate and coverage.
