How is overspray defined in the context of pesticide application?

Overspray in the context of pesticide application is defined as spray that misses the target. This occurs when the spray intended for a specific area ends up outside of that area, landing on non-target surfaces. This can lead to unintended exposure to the pesticide for plants, animals, or humans in those adjacent areas, which is a significant concern in application practices.

This definition highlights the importance of precision in pesticide applications. Proper calibration of equipment and choosing the right environmental conditions for application can help minimize overspray. While other terms like drift, excess application, or runoff relate to broader aspects of pesticide management, they do not specifically capture the essence of overspray, which is a critical factor in ensuring effective and responsible pesticide use. Understanding overspray helps applicators maintain compliance with regulations and minimize environmental impact.
