What does the term Pesticide Resistance refer to?

Pesticide resistance refers to the ability of pests, such as insects, weeds, or diseases, to survive and reproduce following exposure to a pesticide that was previously effective against them. Over time, repeated or excessive use of certain pesticides can lead to the selection of individuals within a pest population that can tolerate the active ingredient. These resistant pests can pass their resistance traits to their offspring, resulting in a population that is increasingly difficult to control.

This phenomenon is a significant concern in pest management as it can lead to decreased efficacy of various pesticides, requiring the use of larger quantities or more potent chemicals, which often has economic and environmental implications. Understanding pesticide resistance is crucial for developing integrated pest management strategies and for rotating chemical classes to help mitigate this risk.
