CONSTITUTION:A herbicidal composition containing alpha-(beta-naphthoxy)propionanilide expressed by formula I, N-(alpha,alpha-dimthylbenzyl)-alpha-bromo-tert-butylacetamide expressed by formula II and 2-chloro-2',6'-diethyl-N-(butoxymethyl)- acetanilide expressed by formula III (at 1:0.3-0.9:0.2-0.6 weight ratio) or the compound expressed by formula I, compound expressed by formula II and 2- chloro-2',6'-diethyl-N-(n-propoxyethyl)-acetanilide (at 1:0.3-0.9:0.1-0.3 weight ratio) as active constituents. The composition can be safely used in a period from the stage before the rice-planting to any stage after the rice-plating without phytotoxicity to rice plants.
