Which of the following is essential to manage drift during an aerial pesticide application?

• A. Follow label directions
• B. Increase spray pressure to improve coverage
• C. Fly at a very low altitude near obstacles
• D. Ignore buffer zones

Answer: (A)

Managing drift centers on using the product exactly as the label directs, because the label specifies the drift-control measures that were tested for that product. It tells you the appropriate wind conditions, droplet size and nozzle type, spray pressure and rate, and any required buffer zones or drift-reduction practices. When you follow those directions, you’re applying the pesticide in the manner intended by the product’s guidelines, which helps keep off-target movement to a minimum and protects people, wildlife, and sensitive areas while staying compliant with regulations.

Raising spray pressure tends to create smaller droplets that are more easily carried by air currents, increasing drift. Flying very low near obstacles can trigger unpredictable air movement and is dangerous, often increasing drift risk. Ignoring buffer zones violates the label and allows drift into non-target areas.
