Abstract

Mode of action of a new herbicide, benthiocarb [S-(4-chlorobenzyl) N,N-diethylthiolcarbamate, trade name: Saturn], was investigated. The herbicide had little effect on the Hill reaction of spinach chloroplasts, and on both photosynthesis of whole plants and respiration of excised roots in rice plant (Oryzae sativa) and barnyardgrass (Echinochloa crusgalli). Benthiocarb inhibited the a-amylase synthesis induced by added gibberellin in rice- and barnyardgrass-endosperms, but had no effect on the hydrolysis of starch by α-amylase preparation itself. It also inhibited the elongation of the laminaioints of excised rice leaves induced by added indoleacetic acid (IAA). In this case, benthiocarb jointly acted in an antagonic way, namely competitively, with IAA. From these results, the inhibition of protein synthesis through the competition at the auxin-acting site seemed to be one of the mode of actions of the herbicide.
