What does "residue" refer to in pesticide usage?

The term "residue" in the context of pesticide usage specifically refers to the traces of pesticide that remain on surfaces after application. This can include small amounts that are left on plants, soil, or other treated areas. Understanding the concept of residue is essential for ensuring safety and compliance with regulations, as it involves evaluating how much pesticide is left and how it may affect the environment or enter the food chain.

Residual pesticide can vary based on the method of application, the type of pesticide used, environmental conditions, and the timing of the application. It is important to recognize that while some residue may be acceptable, excessive amounts can lead to potential health risks for humans, wildlife, and beneficial organisms. Hence, managing residue properly is a key aspect of integrated pest management and responsible pesticide use.
