The 2008 edition of the Illinois Agricultural Pest Management Handbook was the final edition of a publication that served pest management practitioners for many decades. Herbicide information and annual updates of product performance ratings were mainstays of that publication. Since 2008 we periodically have published herbicide performance ratings, but admittingly not with a great deal of consistency. Recently, the weed science programs at The Ohio State University and Purdue University extended an invitation to the University of Illinois weed science program to join them in the production of their joint weed control publication. The 2015 Weed Control Guide for Ohio, Indiana and Illinois contains 212 pages of weed management information, including weed response ratings for corn and soybean herbicides. Information and recommendations for managing weeds in small grains and forages is included, along with more specific information about and control recommendations for several problem weed species. A pdf of the 2015 Weed Control Guide is available to download, and a printed version of the guide can be ordered at: http://estore.osu-extension.org/productdetails.cfm?PC=2860
