Which statement best describes a drift management plan for pesticides?

• A. A plan focusing only on nozzle size and color of pesticide.
• B. A plan that ignores weather and uses random droplet sizes.
• C. A plan including nozzle type, droplet size, application height, wind speed restrictions, and buffer zones.
• D. A plan to maximize drift and reduce buffer zones.

Answer: (B)

Drift management is about keeping pesticide spray on target by controlling how droplets travel through the air. A good plan brings together several factors that directly influence how far and where spray droplets move. It starts with the nozzle type and the droplet size because these determine how fine or coarse the spray is; coarser droplets tend to drift less but still provide needed coverage when chosen appropriately for the product and target. It also specifies the application height, since spraying from too high a height can let the plume travel farther off target. Weather considerations, especially wind speed, are key too because wind pushes droplets sideways; a plan sets limits on when conditions are suitable to spray to minimize drift. Finally, including buffer zones creates safe space between the treated area and non-target sites like sensitive receptors or water bodies, further reducing exposure risk.

This combination—nozzle type, droplet size, application height, wind speed restrictions, and buffer zones—best describes a drift management plan because it addresses the main levers that control spray movement and protect surrounding areas. The other options describe incomplete or unsafe approaches, such as focusing only on nozzle size, ignoring weather and droplet behavior, or aiming to maximize drift and shrink buffer zones.
