PURPOSE:To obtain a herbicide compound having high herbicidal effects, wide weed destroying spectrum and safety to crops by using a specific compound having herbicidal effects and chlorosulforon or metsulfuron-methyl well-known as a herbicide. CONSTITUTION:(A) a compound shown by formula I is blended with (B) chlorosulforon shown by formula II or metsulfuron-methyl shown by formula II as active ingredients in the ratio of 0.01-50 pts.wt., preferably 0.02-20 pts.wt. component B based on 1 pt.wt. component A to give a herbicide composition which synergistically increases herbicidal effects of each component, enlarges weed destroying spectrum and can selectively destroy various weeds, especially weeds in a wide range in grain fields of wheat, barley, etc., with a smaller amount of component compared with a separative use of each compound without phytotoxicity to crops. |
