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 broader herbicidal spectrum, a high activity and a long-lasting effect. The present invention provides a herbicidal composition comprising, as active ingredients, (a) flazasulfuron or its salt and (b) metribuzin or its salt.
