Glyphosate-Resistant Weeds in Orchards - Recent UC IPM Publications

Last winter, I particpated in a series of seven half-day workshops in California, Oregon, and Washington on herbicide-resistant weeds.  These workshops were organized by Kassim Al-Khatib from the Univeristy of California Integrated Pest Management (IPM) Program and had a special focus on glyphosate-resistant weeds in tree and vine crops.In preparation for these workshops, we wrote a series of extension publications that I wanted to share today.  The publications and resulting presentations were prepared by weed scientists from various Universities, Cooperative Extension, and USDA-ARS and included various aspects of herbicide resistance in permanent crops.  Even as somone who thinks about herbicide resistance every day, I found the bulletins and presentations to be tremendously informative.  These included:Selection Pressure, Shifting Populations, and Herbicide Resistance and Tolerance by Brad Hanson, Albert Fischer, Anil Shrestha, Marie Jasieniuk, Ed Peachey, Rick Boydston, Tim Miller, Kassim Al-Khatib.
