What is the primary responsibility during an aerial application to manage off-target pesticide drift?

The primary responsibility during an aerial application to manage off-target pesticide drift primarily lies with the pilot. This is because the pilot controls the aircraft and is directly responsible for making operational decisions that can influence drift, such as altitude, speed, and application rates. The pilot must be aware of environmental conditions like wind speed and direction, which significantly affect where the pesticide may drift.

In practice, the pilot is trained to assess the situation and make real-time adjustments to minimize the risk of drift. Additionally, pilots should be knowledgeable about applicable regulations and best practices that guide safe aerial application to ensure environmental protection.

While other parties, such as the applicator, ground crew, and regulatory agencies, play supportive roles in helping mitigate drift—like obtaining permits, preparing the site, and enforcing regulations—the ultimate in-flight decisions that impact drift management rest with the pilot.
