Abstract: Provided is an herbicidal composition which can be applied at a low dose as compared with individual application, and thus is effective to reduce the environmental load on a place where the composition is applied or a periphery thereof, of which the herbicidal spectrum is enlarged, and of which the herbicidal effects last over a long period of time. The herbicidal composition has as active ingredients (a) a herbicidal benzoylpyrazole compound represented by the formula (I) or its salt: wherein Q is —C(O)SR3 or a hydrogen atom, R1 is alkyl or cycloalkyl, R2 is a hydrogen atom or alkyl, R3 is alkyl, cycloalkyl or the like, R4 is alkyl, haloalkyl or the like, R5 is a hydrogen atom, alkyl or the like, R6 is haloalkyl, halogen or the like, and (b) a further herbicidal compound.
