Abstract

Barnyardgrass (Echinochloa crusgalli (L.) Beauv.) seeds which did not germinate because of low temperature, insufficient moisture, or seed dormancy were exposed to concentrations of ethyl N,N-di-n-propylthiolcarbamate (EPTC) lethal to emerging barnyardgrass seedlings. After different periods of exposure, seeds were removed from the EPTC-treated environments and germinated in untreated soil. Seed germination was not reduced by EPTC and there was no permanent injury to the seedlings. It was concluded that rates of EPTC used for selective weed control do not injure barnyardgrass seeds prior to germination.
