What is an important benefit of using pesticides as a last resort in IPM?

Using pesticides as a last resort in Integrated Pest Management (IPM) is crucial because it helps prevent the development of pest resistance. This is a significant benefit since repeated exposure to the same chemical compounds allows pests to adapt over time, leading to populations that are resistant to those pesticides. By using chemical controls sparingly and only when necessary, pest populations are less likely to become resistant, ensuring that the pesticides remain effective when they are ultimately needed.

In IPM, the strategy prioritizes non-chemical control methods and only utilizes chemical interventions after evaluating other options. This approach helps maintain the efficacy of available pesticides, which is essential for sustainable pest management in both agricultural and non-agricultural settings. Such a sound practice contributes to long-term pest control success and minimizes reliance on chemical inputs.
