What term describes the time it takes for a pesticide to break down after application?

The term that describes the time it takes for a pesticide to break down after application is persistence. When discussing pesticides, persistence refers to the duration that the active ingredients remain unchanged in the environment before undergoing decomposition or transformation into other substances. This is an important factor in determining how long the pesticide will be effective, as well as its potential environmental impact.

Understanding persistence helps applicators assess the risks associated with pesticide use, including potential effects on non-target organisms and the environment. The longer a pesticide persists, the greater the chance it may have unwanted effects beyond its intended application area.
