What is the term for the movement of airborne spray particles away from the intended application area?

The term that describes the movement of airborne spray particles away from the intended application area is referred to as spray drift. Spray drift occurs when small droplets or particles of a pesticide or herbicide become airborne during the application process, often due to wind, thermal currents, or equipment malfunction. This movement can lead to unintended exposure to non-target areas, such as neighboring plants, water bodies, or residential areas, potentially causing harm to those environments or organisms.

Understanding spray drift is essential for effective weed management and environmental protection, as it emphasizes the need for careful application techniques and equipment adjustments to minimize unintended off-target movement. Correctly identifying and managing spray drift contributes to integrated pest management strategies and ensures compliance with local regulations regarding pesticide use.
