Which application method might minimize the drift of pesticides during aerial spraying?

Applying at lower altitudes is an effective method to minimize the drift of pesticides during aerial spraying. When the aircraft is flying at a lower altitude, it reduces the distance that the spray droplets must travel before reaching the target area. This proximity helps ensure that more of the pesticide remains on the intended application zone rather than being carried away by wind currents.

Additionally, lower altitudes can lead to increased turbulence near the ground, which can help droplets settle more quickly. The reduced wind influence at these altitudes means that there is less chance for the pesticide to be carried off-target, thereby improving the efficiency of the application and minimizing potential environmental contamination.

Higher flying altitudes, larger nozzles, and high-pressure systems can all contribute to increased drift potential, primarily because they create smaller droplets or allow the spray to be affected more by wind conditions. Thus, maintaining a lower altitude during aerial spraying is a critical practice for effective pest management and environmental safety.
