What is the Iowa Pest Resistance Management Program?

The Iowa Pest Resistance Management Program (IPRMP) is an Iowa-specific effort 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.

Harrison History

The Harrison County landscape includes both hills and valleys. Farming techniques differ depending on the topography of the farm because what works in the valleys does not work in the hills and vice versa. Tillage is not used in the Loess Hills but it is in the bottoms.As seen in 2019, flooding on the Missouri River bottoms is a significant challenge that affects management. Deposition of sand affects how locals farm, and weed seeds are spread during flooding as well. The high water table affects other aspects of management.

Harrison Pests

The Harrison County Pest Resistance Project initially began in 2017 as a result of the introduction of Palmer amaranth in the county four years prior. As most farmers in the area are grappling with herbicide resistant weeds but do not have Palmer in their fields yet, the project was expanded to include waterhemp, marestail, giant ragweed and disease trials as well. Read below to learn more about local disease and weeds and why they were included in this project.

Harrison Outreach

Outreach for Harrison County includes field days, presentations a local events, videos and news articles. Handouts have been distributed at local retailers and county events (Harrison County crop fair, Private Pesticide Applicator Training, Denison/Atlantic Crop Advantage Series). The project has been mentioned or promoted at the local crop fair, local extension events, and the county extension board meetings.

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.
