What is the definition of overspray in pesticide application?

The definition of overspray in pesticide application refers to the application of pesticides beyond the designated target boundaries. This occurs when pesticides are unintentionally applied to areas outside of the intended zone, which can lead to unintended exposure of non-target organisms, contamination of water sources, or damage to desirable plants. Understanding this concept is crucial for effective pest management and environmental protection, as it emphasizes the importance of accurate application techniques and careful planning of treatment zones to minimize the risks associated with pesticide use.
