Generic Herbicide List?

Chris Boerboom, Ext. Weed Scientist

I was recently asked if I had a list of generic or post-patent corn and soybean herbicides.  While I would like to maintain such a list, it is a difficult task considering the number of new trade names that are continually entering the market.  Although I don’t have a list, I would recommend the Department of Agriculture, Trade, and Consumer Protection web site of “Pesticide Database Searches” at http://www.kellysolutions.com/wi/.  The first database option listed is a Pesticide Registration Search.  For example, if you want to know the other products that contain the active ingredient in Select.  Click on “Search by active ingredient” and enter clethodim.  When “clethodim” is returned, click on it and you will get a list of Wisconsin registered products with clethodim, including Select, Trigger, Envoy, Arrow, etc.  This is a handy web site to have bookmarked for future use.
