DECATUR, Ill. (DTN) -- Midwest corn and soybean fields got ugly this summer. Marestail, waterhemp, Palmer amaranth and giant ragweed wreaked havoc across America's croplands. Some old challengers also returned -- velvetleaf, milkweed, morningglory and even the prickly old cocklebur.

Southern Illinois University weed scientist Bryan Young got something this summer he never expected. "I had a grower call to say that he'd applied a full rate of a residual herbicide and had waterhemp come through it. He followed up with glyphosate and FlexStar and the waterhemp was hardly fazed. A second shot of glyphosate and Cobra failed as well.
