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.

What is the Iowa Pest Resistance Management Program?

The Iowa Pest Resistance Management Program is a grassroots, collaborative effort to protect Iowa crops from costly pest resistance that threatens our crop production and our state’s economy. The program is made up of individuals and groups representing all parts of the Iowa community, including farmers and landowners, small and national businesses, scientists, researchers and state regulators. Together, these groups and individuals have leveraged their resources, expertise and time to help inform the public about pest resistance, find new pest management strategies and encourage public support and adoption of these practices.

How can you get involved?

The Iowa Pest Resistance Management Program (IPRMP) was designed for you to get involved. The program features four pilot programs across the state that are working to combat various types of pest resistance. These include: Managing Western Corn Rootworm in Northeast Iowa; the Harrison County Pest Resistance Management Project in Southwest Iowa; Managing Soybean Aphid in Northwest Iowa; and Managing Herbicide-Resistant Waterhemp in Story County. To learn more about the IPRMP and the pilot programs, check out the Q&A here. To learn how you can lend your support or develop your own community project, please email isuipm@iastate.edu.

EPA Releases Guidance on Slowing Pest Resistance

November 14, 2017

The U.S. Environmental Protection Agency (EPA) recently released two pesticide registration notices (PRNs) that impact how technology providers, crop advisers, and producers manage resistance. These documents are in addition to a new framework to address Bt resistance in corn rootworm released in 2016. These releases, which all went through public comment, provide guidance in managing resistance and support the strategies and goals of the Iowa Pest Resistance Management Program (IPRMP).
