From an article appearing in Chem-O-Gram, June 2002

If you are interested in Herbicide resistance, here is a useful resouce. An international group of weed scientists has produced an international survey of herbicide-resistant weeds, including 258 biotypes and 156 species (94 dicots and 62 monocots). The data fields can be searched by nomenclature (both common and scientific), location, or herbicide mode of action. You will also find recent publications on herbicide resistance and links to other materials. It is all on the web at www.weedscience.org.
