Explanation:
The 2nd basic rule of an Integrated Pest Management (IPM) program is to rely on non-chemical measures to keep pest populations low. This means prioritizing ecological pest control methods and cultural practices over the use of synthetic pesticides. These can include the use of pest resistant cultivars, interplanting, and the use of physical traps. When chemical pesticides are needed, they are considered a last resort and should be chosen and applied in a manner that minimizes their environmental impact, such as selecting non-persistent products and using them in a targeted way.
