The Harrison County Pest Resistance Management Project is an effort to address the growing challenge posed by resistant pests. Since pests spread easily by wind, water, wildlife and equipment, resistance management is the responsibility of everyone involved in agriculture. A team of farmers, agronomists, crop advisers, researchers, bankers, agribusiness professionals, seed and herbicide company professionals and landowners is working to increase collaboration, spread awareness, and find solutions to resistance issues to ensure that pest resistance management is an integral part of all agricultural business decisions. While the project began with a focus on waterhemp, marestail, giant ragweed, and palmer amaranth, the team decided to expand and address disease resistance as well. This project is one of several resistance management projects being implemented across Iowa as part of the Iowa Pest Resistance Management Program (IPRMP).
The Harrison Project has completed field trials and resistance screenings and has held field days and a field tour.
To reduce the spread and development of herbicide resistance, the use of diverse weed management programs are essential, including timely applications of herbicide mixtures containing multiple, effective mechanisms of action in addition to cultural and mechanical techniques where feasible. Due to high seed production in many weed species, all efforts to reduce and prevent seed production by resistant individuals will be highly beneficial.
