During aerial application, which device helps reduce drift?

• A. Drift-control nozzles
• B. Higher spray pressure
• C. Smaller droplets by using a finer nozzle
• D. Apply under windy conditions

Answer: (A)

Drift during aerial spraying is minimized by producing larger droplets, which are less likely to be carried off target by wind. Drift-control nozzles are designed to create coarser droplets (often using air-induction) and to shape the spray so it deposits more on the target and less in surrounding areas. That makes them the best option for reducing drift among the choices. Higher spray pressure tends to break the liquid into smaller droplets, increasing drift risk. Using a finer nozzle also creates smaller droplets and more drift potential. Applying under windy conditions naturally increases drift rather than reduces it.
