Nutsedge, Cyperus rotundus L., is one of the most serious perennial weeds in upland fields of Japan, and EPTC (ethyl N, N-dipropylthiocarbamate) has been found to be effective to the control of this weed. This experiment is undertaken to obtain some informations about effects of EPTC on nutsedge tuber germination. The results obtained are as follows: (1) EPTC remarkably inhibited the germination without killing the tubers and induced, so called, dormant state. (2) The dormancy induced by EPTC was broken when the tubers were immersed into gibberellin (GA_3) solution, (3) No obvious changes were observed in contents of carbohydrates and also in O_2-consumption during the germination stages. It appears, therefore, that a mode of action of EPTC is the inhibition of GA_3 synthesis.
