What is the ideal flight speed for aerial application of pesticides?

The ideal flight speed for aerial application of pesticides is typically in the range of 80 to 120 miles per hour. This speed allows for efficient coverage of the target area while facilitating effective dispersion and penetration of the pesticide into the target environment. When the aircraft operates within this speed range, it can also help minimize the potential for drift, ensuring that the pesticide reaches the intended area more effectively and reduces the risk of unintended spray contamination to surrounding plants, water, or non-target organisms.

Flying at higher speeds can lead to an increased risk of drift, decreasing the accuracy of application due to wind effects, and can also result in poor deposition on target plants due to rapid air movement around the aircraft. Conversely, flying too slowly may not provide sufficient coverage in a timely manner and could increase the time of exposure for non-target environments, making the application less efficient and more hazardous. Therefore, the 80 to 120 miles per hour range strikes an optimal balance between efficiency, safety, and effectiveness in aerial pesticide application.
