Abstract

The phytotoxicity of 3-[p-(p-chlorophenoxy)phenyl]-1,1-dimethylurea (chloroxuron) usually decreased as the stage of growth of five weed species at treatment increased. Giant foxtail (Setaria faberii Herrm.), velvetleaf (Abutilon theophrasti Medic.), and the cotyledonary stage of cocklebur (Xanthium pensylvanicum Wallr.) were most resistant to the herbicide. Ivyleaf morningglory (Ipomoea hederacea (L.) Jacq.) and jimsonweed (Datura stramonium L.) were more susceptible to chloroxuron. Soybean (Glycine max (L.) Merr.) seemed less susceptible at the cotyledonary stage than at later stages. Phytotoxicity on both weeds and soybeans was increased by increased temperature and relative humidity following chloroxuron application. The phytotoxicity of chloroxuron also was increased by simulated rainfall in greenhouse studies.
