How is "overlap" defined concerning spray patterns in pesticide application?

The definition of "overlap" in the context of spray patterns in pesticide application pertains to the percentage area that is covered by pesticide during a single pass. When applying pesticides, achieving appropriate overlap is crucial to ensure uniform coverage of the target area without leaving untreated spots.

When nozzles are positioned in a way that allows the spray patterns from adjacent nozzles to intersect, this creates overlap, which helps mitigate gaps in coverage. Understanding this concept is vital for calibrating sprayers effectively to enhance pesticide efficacy and ensure compliance with application standards. Proper overlap ensures that the necessary amount of pesticide is applied uniformly across the intended area, promoting effective pest control and minimizing wastage.
