What is the most effective boom length for reducing drift during aerial applications?

The most effective boom length for reducing drift during aerial applications is typically considered to be 70% of the wingspan or rotor span. This length strikes a balance between the need for adequate spray coverage and the minimization of off-target drift.

When the boom is optimized at this length, it allows for a more stable spray pattern and helps to keep the spray droplets closer to the target area, which significantly reduces the effects of wind on drift. Longer booms may increase the risk of drift due to the increased distance from the aircraft to the target, while shorter booms may not provide sufficient coverage for effective pest control.

In aerial applications, keeping the boom at about 70% of the wingspan or rotor span allows operators to maintain efficiency in their applications while effectively managing the risk of pesticide drift, benefiting both the target crops and the surrounding environment.
