Although researchers and industry personnel have made recommendations to slow the evolution of herbicide-resistant weeds, an understanding of the patterns and causes of the resistance has been limited. A recently published study looking at glyphosate-resistant waterhemp is providing valuable evidence that points to management practices as the driving force behind herbicide resistance, and that herbicide mixing, as opposed to herbicide rotation, is the most effective tool in managing resistance.
