Weeds and Weed Control
Herbicide Resistance and Weed Management Course
Plan ahead. Dealing with herbicide resistance can be expensive. The United States Department of Agriculture estimates the cost of dealing with herbicide resistance once it occurs to be $20 to $60 per acre. Developing long-term weed management plans that reduce the chances of resistance developing will minimize the cost of resistance. However, it's a team effort - farmer, retailer, and industry - working together to delay herbicide resistance.
This online, interactive and self-paced course contains narrated presentations, lesson activities and resources to provide farmers and agribusiness professionals the tools to develop long-term weed management plans to help delay the development of herbicide resistance.
Those who complete the course are eligible for 3.0 integrated pest management Certified Crop Adviser continuing education units. In order to receive CCA credits, the entire course must be completed
The materials for this online course were originally developed by Iowa State University and Outreach field agronomists along with weed scientists Bob Hartzler and Mike Owen for a series of face-to-face Weeds Week workshops.
