Getting Rid Of Weeds
Through Integrated Weed Management
We are a scientist-led network coordinating research to help farmers across the U.S. fight herbicide-resistance with a greater diversity of weed control strategies to complement chemical use.
GROW aims to provide information on tools such as cover crops, increased crop competition, harvest weed seed control, and more.
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:
