What is particle drift?

Particle drift refers to the phenomenon where solid particles, such as herbicide formulations or other chemicals, are transported through the air from the intended application site to unintended areas. This movement can occur due to various factors like wind speed, temperature, and humidity, and it is a significant concern in herbicide application because it can lead to the unintentional exposure of non-target plants and environments.

Understanding this concept is crucial for herbicide applicators, as effective management of particle drift helps ensure that herbicides are applied accurately and responsibly, minimizing the risk of environmental contamination and damage to non-target species.
