Who is ultimately responsible for the misapplication of pesticide if a pilot applied twice as much treatment as recommended?

The pilot bears the primary responsibility for the misapplication of pesticide, particularly when it pertains to the amount of treatment applied. In aerial application, pilots are trained professionals who must adhere rigorously to the recommended guidelines for pesticide use, including dosage rates. These guidelines are established to ensure not only the effectiveness of the treatment but also the safety of the environment, non-target organisms, and human health.

When a pilot deviates from these established protocols, such as applying double the recommended amount, it is within their responsibility to know and implement the correct application rates. Regulatory agencies also emphasize the need for pilots to be knowledgeable about the products they are using and comply with all applicable federal, state, and local laws regarding pesticide application.

While other parties, such as the agricultural manager, ground crew, or pesticide manufacturer, have roles that can influence the process, they do not have direct control over the actions taken by the pilot during the application. The pilot is on the front line, executing the aerial application, thus making them the decision-maker responsible for adhering to recommended practices.
