Herbicides from very different chemical families may have the same mechanism of action. 0000092176 00000 n Atrazine is part of the triazine chemical class which includes simazine and propazine due to their common mechanism of toxicity. As a result, if a weed is resistant to a specific herbicide SOA it is effectively controlled by other herbicides with a different SOA. The molecular site of action is challenging to predict because structural associations have not been identified (Duke 1990), but modes of action are well-established. Mode of Action Classification IRAC promotes the use of a Mode of Action (MoA) Classification of insecticides and acaricides as the basis for effective and sustainable resistance management.
