dicamba 939 dicamba (240) First draft prepared by Dr. Yukiko Yamada, Ministry of Agriculture, Forestry and Fisheries, Tokyo, Japan EXPLANATION dicamba , a systemic broad-spectrum herbicide, is used in a variety of crops. Its mode of action is similar to that of endogenous auxin (IAA) and other auxin-type herbicides and appears to involve cell wall plasticity and nucleic acid metabolism. In sensitive broad-leaved weeds, the induction of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase in the biosynthesis of ethylene is a primary and rapid response to auxin herbicides. Within a few hours after treatment, increases are induced in ACC synthase activity, followed by increased ACC concentration and ethylene formation in the shoot tissue.
