What is the purpose of using an anti-drift agent in aerial applications?

The primary purpose of using an anti-drift agent in aerial applications is to reduce pesticide drift during application. Drift occurs when small droplets of pesticide are carried away by wind or other forces, which can lead to unintended application on non-target areas. Using an anti-drift agent helps to modify the physical properties of the spray solution, often increasing droplet size or altering the surface tension, making it less likely for droplets to become airborne and drift away from the target area. This not only ensures that the intended area receives adequate treatment but also minimizes potential environmental impact and harm to non-target organisms.

While increasing pesticide absorption, enhancing visibility of the spray, and shortening application time are important considerations, they are not the primary function of an anti-drift agent. The main goal is to ensure that the pesticide remains on the intended target area, promoting effective pest management and safety in aerial application operations.
