The continual evolution of weed populations resistant to herbicides from one or more site-of-action groups, including Group 15 herbicides, represents one of the most daunting challenges faced by farmers and weed management practitioners. This fact sheet discusses the management of weeds to mitigate development of resistance in Group 15 herbicides, including an overview of the state of Group 15 herbicide resistance as well as a look into how researchers test for herbicide resistance in this site of action.
