Yesterday I headed up to Minden City, MI with Christy Sprague and our newest master’s student, Amanda Harden. We were there to rate an on-farm research plot, looking at windgrass control in wheat using fall and spring applied herbicides. Windgrass is a winter annual weed, meaning it germinates in the fall, overwinters, and produces seed in the spring, putting it in direct competition with wheat. Windgrass could be confused with annual bluegrass, another winter annual, however the membranous ligule of windgrass is more jagged at the top, whereas the ligule of annual bluegrass is smooth. Additionally, the sheath of windgrass is rounded, whereas the sheath of annual bluegrass is more flattened. Look for the results this windgrass control study during the winter extension meetings and on MSUweeds.com.
