Getting Rid Of Weeds
Through Integrated Weed Management
We are a publicly led network coordinating research and outreach, providing science-based information and decision support tools to make agriculture more sustainable and precise. We work to develop integrated weed management solutions that are practical and adoptable.

No Seeds. No Weeds.
For over 50 years, herbicides have been a highly effective method to control weeds and protect crop yields. Herbicides have supported the wide-spread use of no-till and limited cultivation for weed control, improving soil health. However, over reliance on a few key herbicides has caused the development of particularly problematic herbicide-resistant weeds.
For some farmers, herbicides alone just aren’t getting the job done anymore.
Integrated Weed Management (IWM) is the answer.
What is Integrated Weed Management?
Integrated weed management (IWM) combines various methods to reduce or eliminate the effect of weeds on crop production over time, using a combination of practices that are most effective for solving specific weed issues. Techniques include:
