What are the primary causes of drift?

The primary causes of drift are closely associated with the influence of wind and the presence of small droplets during application processes. Drift occurs when pesticide droplets or particles are carried away from the intended target area by wind currents. Even a light breeze can significantly affect the trajectory and settling of these tiny droplets, causing them to disperse over unintended areas, which can lead to environmental contamination or damage to non-target plants and organisms.

Additionally, small droplets are more susceptible to movement because their lighter weight and smaller size allow them to be easily lifted and carried by wind. Therefore, understanding the dynamics of wind in relation to droplet size is crucial for effective and responsible pesticide application. Proper techniques, such as choosing the right application method and time, can mitigate the effects of drift and ensure that treatments stay within designated boundaries.
