Pests

Resistance is showing up in weeds, insects and disease pathogens in Iowa and has the potential to impact yields, increase the cost of production, and limit farmers’ future
pest management options.

Examples of Resistant Weeds

Common cocklebur, common lambsquarters, common sunflower, giant foxtail, giant ragweed, horseweed, Kochia, Pennsylvania smartweed, waterhemp, and recently, Palmer amaranth.

Examples of Resistant Insects

Western corn rootworm, also soybean aphid populations near, but not yet inside, Iowa.

Examples of Resistant Diseases

Soybean cyst nematode and frogeye leaf spot.

Pilot projects will be selected from these pest options and will be used to inform management option strategies as well as collaborative efforts within communities to resolve resistant pest issues.

What is the Iowa Pest Resistance Management Plan?

The Iowa Pest Resistance Management Plan (IPRMP) is an Iowa-specific plan to address pests--including weeds, insects and diseases--that can adapt and become resistant to chemical, genetic, and agronomic control practices. The IPRMP outlines approaches for effective, integrated management solutions that will sustainably control pests. By fostering methods to detect resistance, resistance can be delayed or even prevented, limiting the spread of pest resistance.

Version 1 of the IPRMP is an Iowa-specific plan that seeks to engage farmers on the issue of pest resistance management with the goal of keeping technology and tools such as pesticides, seed treatments and biotechnology products and native traits available and effective.

Diligent Management Still Key to Avoid Spread of Palmer Amaranth in Iowa Fields

August 25, 2017

DES MOINES - State, federal and extension experts are encouraging Iowa farmers to stay vigilant in their efforts to control Palmer amaranth. Iowa lawmakers added this fast-growing weed to Iowa’s noxious weed list in July as a response to a significant increase in the presence of Palmer across Iowa in 2016.

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).
