many herbicidal compositions have already been developed and used, but there are many types of weeds to be controlled, and their development takes a long time. therefore, it has been sought to develop a herbicidal composition that has a broader herbicidal spectrum and that has a highly active and long-lasting herbicidal activity. the present invention offers a herbicidal composition comprising as active ingredients (a) a benzoylpyrazole herbicidal compound represented by formula (i) or its salt: where r1 is alkyl or cycloalkyl, r2 is a hydrogen or alkyl atom, r3 is alkyl , r4 is alkyl, haloalkyl among others, r5 is a hydrogen atom, alkyl among others, r6 is haloalkyl, halogen among others, and a is alkylene substituted with alkyl, and (b) another herbicidal compound. |
