Abstract

Many herbicidal compositions have been developed and practically used. However, types of weeds to be controlled are also many, and their emergence extends over a long period. Accordingly, it is desired that a herbicidal composition be developed which has a wider herbicidal spectrum and which is highly active and has a long lasting effect. A herbicidal composition comprising (A) a compound of the formula (I): wherein R is a hydrogen atom or -COCH2OCH3, or its salt, and (B) at least one compound selected from the group consisting of (B1.1) mefenacet, (B1.2) fentrazamide, (B1.3) oxaziclomefone and (B2.1) clomeprop, or its salt, as active ingredients.
