What’s the deal with pest resistance?

Pests – insects, disease and weeds -- are a regular part of life. For large areas, our pest removal practices have included spraying safe pesticides or relying on plant genetics to manage them. But many pests can reproduce quickly and often, allowing them to evolve and develop tolerance to some of our easiest, cheapest and most effective management tools. Some pests are completely tolerant to some pesticides. When this occurs, it is called pest resistance, because they can now resist and survive a specific management tactic that previously controlled them.

Pest resistance is a natural process. However, when it comes to something as valuable as our food and when there’s no easy way to fight a pest, it can lead to yield reductions and increasing costs. Farmers, landowners, scientists, private businesses, and groups of individuals are finding ways to preserve our management tools, prevent pest resistance, and develop management strategies for already resistant pests.
