Glyphosate-/multiple-resistant horseweed (marestail) is fairly common in many of Michigan’s no-till soybean fields (Figure 1). In fact, of the 18 horseweed samples that were tested for resistance this winter by MSU Diagnostic Services 100% of them were resistant to glyphosate (Group 9) and 78% of them were resistant to both glyphosate (Group 9) and the Group 2 (ALS) herbicides. Because of resistance problems and weather conditions that favored horseweed emergence last year, horseweed control failures were common in soybean.

Over the next month, many of Michigan’s winter wheat acres will be treated with herbicides for weed control. While there are several herbicide options available for use in wheat, there are many factors that growers should consider prior to deciding when to spray and what products to use.
