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 widespread use of no-till and limited cultivation for weed control, improving soil health. However, overreliance on a few key herbicides has prompted a growing epidemic of 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) is a system that layers multiple weed control methods to suppress and manage weeds across a growing season, by targeting weeds and the seedbank in different ways and at different stages of development. The result is a robust weed management program that doesn’t rely on a single mode of action or management tactic. IWM techniques include:
