The Weed Science program at the University of Missouri administers extension, research and teaching programs to keep you informed of the latest findings in weed control.
Our online resources include a Missouri weed ID guide, which is also available as the app ID Weeds, and a herbicide injury guide. Both of these guides are full of photos — to aid in the identification of a weed or the diagnosis of herbicide-caused crop injury, respectively. In addition, we offer numerous publications, newsletter articles, videos and PowerPoint presentations on various aspects of weed control.
If you are interested in seeing the results of specific field trials, go to our research results page. There you can search for results from our field research by year, herbicide, weed or crop.
