Farmers in Illinois, other states too, are struggling to control glyphosate resistant weeds. Marestail can be one of the most challenging under no-till conditions prior to planting soybeans. More often than not farmers are using a tank mix of glyphosate and 2,4-D (two-four-dee). Sometimes the problem is that the weed is already too big to control, at others says University of Illinois Extension Weed Scientist Aaron Hager is its just that the 2,4-D isn’t doing the job any better than the glyphosate.
