There are signs of potential waterhemp herbicide resistance in Missouri.
University of Missouri weed scientist Kevin Bradley told participants at the MU Pest Management field day his department is proactively studying the effects of dicamba and glufosinate on waterhemp.
“Can I sit here and say we have an official dicamba resistant waterhemp? No. But, we have several suspicious populations that aren’t dying and we’re looking into them in more detail.” Bradley points out there is already dicamba resistant palmer amaranth weeds in the South.
