Past, Present and Potential Future of Herbicide-Resistant Crops

Dr. Stephen Duke, USDA-ARS

The most successful transgenic crops have been those made resistant to the herbicide glyphosate. However, the evolution of glyphosate resistance in problem weeds is rapidly reducing the value of this technology. The potential of new herbicide-resistant crops to fill the weed management gaps caused by evolved resistance will be discussed.

Dr. Duke is the Research Leader of the USDA-ARS Natural Products Utilization Research Unit, which is embedded in the School of Pharmacy at University of Mississippi in Oxford. Steve is probably best known for his research on the modes and mechanisms of action of herbicides. He has published almost 400 journal articles and book chapters and is Editor-in-Chief of Pest Management Science.
