giant ragweed in soybean field.AMES, Iowa – Designing an effective weed management plan to combat troublesome weeds and delay the development of herbicide resistance requires careful planning. The United States Department of Agriculture estimates the cost of dealing with herbicide resistance once it occurs to be $20-60 per acre. Developing long-term weed management plans that reduce the chances of resistance developing will minimize the cost of resistance.

An online course offered through Iowa State University Extension and Outreach, titled “Herbicide Resistance and Weed Management,” provides farmers and agribusinesses the tools and resources needed to help design an effective long-term weed management plan to help delay the development of herbicide resistance.

The interactive and self-paced course contains presentations narrated by ISU Extension and Outreach faculty and specialists, along with lesson activities that can be completed according to the user’s timetable.

The cost of the course is $50 and can be purchased through the ISU Extension Store.  

Those who complete the course are eligible for 3.0 integrated pest management Certified Crop Advisor continuing education units. In order to receive CCA credits, the entire course must be completed.
