Many herbicidal compositions have been developed and are presently used. However weeds to be controlled are various in types and their emergence extends over a long period. Accordingly it is desired to develop a herbicidal composition which has a broad herbicidal spectrum a high activity and a long lasting effect. The present invention provides a herbicidal composition comprising (A) flazasulfuron or its salt and (B) at least one protoporphyrinogen oxidase inhibitor selected from the group consisting of a phenylpyrazole compound a triazolinone compound a N phenylphthalimide compound a pyrimidindione compound an oxadiazole compound an oxazolidinedione compound a thiadiazole compound pyraclonil profluazol flufenpyr ethyl and their salts. According to the present invention a herbicidal composition which has a broad herbicidal spectrum a high activity and a long lasting effect can be provided.
