The University of Tennessee Turf & Ornamental Weed Science Team has put together a new website and free mobile app called “Mobile Weed Manual,” located at It is a breakthrough resource for golf course superintendents, athletic field managers, lawn care professionals and even homeowners to assist green industry enthusiasts in selecting herbicides for use in not only warm- and cool-season turfgrass, but an array of ornamentals as well.

End users can search for a weed they want to control and the app gives advice on which herbicides are most effective. “The Mobile Weed Manual contains not only weed control efficacy ratings for problematic weeds of turf and ornamentals, but tolerance information for over 2300 different species, and labels for nearly 100 different herbicides,” said Dr. Jim Brosnan, UT Assistant Professor, Turf & Ornamental Weed Science.  “This powerful resources places all of this research based information in the palm of your hand.”

The site was designed to replace hard copy Extension manuals with a dynamic web interface optimized for use on any mobile device (i.e., smart phones, tablets, etc.). “It is our sincere hope that this becomes a valuable tool for all green industry professionals managing weeds,” Brosnan said.

The QR code below takes users directly to the web site. The web page also has a direct link for Apple and Android users to download the application to their phone or other mobile device.
