• Why No-Spray Buffer Zones Help Ease Environmental Concerns in Invasive Tree Management

    WESTMINISTER, Colorado. November 10, 2023— Invasive conifers are to New Zealand ecosystems what waterhemp is to U.S. soybean farmers. Trees such as lodgewood pine are weeds that quickly outcompete local flora. This has led New Zealand to launch The National Wilding Conifer Management Programme to manage … more »

  • Students Sharpen Skills in National Weed Science Contest

    WESTMINISTER, Colorado, October 30, 2023 – Can you identify a weed species in any growth stage? Or, know all aspects of sprayer calibration, such as required spray volume? This summer, students were tested on such weed science skills and more … more »

  • Weed Science Societies Provide Comments to Improve EPA’s Herbicide Strategy for Endangered Species Mitigations

    The Weed Science Societies suggest nine additional ways to mitigate the impact of herbicides on listed species due to spray drift, which includes decreased buffers for ultra-coarse droplets, additional types of vegetation to intercept spray droplets and grower education. We also suggest six additional ways to mitigate herbicide runoff and erosion, which also includes grower education, more specific terminology for agricultural vs specialty crops as well as assigning more compensatory mitigation points for fields with subsurface drainage or cover crop practices. Most importantly, the Weed Science Societies want to stress that grower education will be the most effective way to implement EPA’s Herbicide Strategy. We recommend a minimum of a 3-5 year phase-in period for the herbicide strategy ESA mitigation practices, which corresponds to the 3-5 year interval that pesticide applicators must be recertified. more »
