Substitute non-resistant plants with pest-resistant ones. Reduce the need for pesticides by using substitutes such as biological control of insects or natural predators which are harmless to the crop. In cases of limited pest infestation, traps or manual removal could substitute for pesticides.

What is a potential consequence of overusing pesticides?
