To investigate the effect on wheat herbicides on establishing clover and oilseed radish cover crops after wheat harvest we are in the process of conducting a large greenhouse trial. Here are some photos of spraying Run 1.
This new video from AgBioResearch highlights the importance of facilities, like the Saginaw Valley Research and Extension Center in Frankenmuth for improving Michigan agriculture. Keep an eye out for some of your favorite weed scientists in the video.
Yesterday Christy Sprague and I traveled up into the thumb to Minden City, MI. Here we have a plot with a grower cooperator looking at windgrass (Apera spica-venti) control in winter wheat. Windgrass is a winter annual grass, so its growing season corresponds well to the wheat season. Today we applied four preemergence treatments and we will return to the sight when the windgrass is ~1″ tall to apply several post-emergence treatments. This will be the second year of this study. The results from the 2011-2012 season can be found on here on MSUweeds.com
We just posted the 2012 Weed Control Research Results. Results will be updated again following harvest.
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.
