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 &#x2014;C(O)SRor a hydrogen atom, Ris alkyl or cycloalkyl, Ris a hydrogen atom or alkyl, Ris alkyl, cycloalkyl or the like, Ris alkyl, haloalkyl or the like, Ris a hydrogen atom, alkyl or the like, Ris haloalkyl, halogen or the like, and (b) a further herbicidal compound.

Herbicidal compositions containing benzoylpyrazole compounds

A benzoylpyrazole compound represented by the formula (I) or its salt, useful as herbicides and intermediates thereof. 

Benzoylpyrazole compounds and herbicides containing them

A thiophenesulfonamide compound having the formula: ##STR1## wherein X is a halogenoalkoxyalkyl group, and Y is ##STR2## wherein A is .dbd.N-- or .dbd.CH--, and each of Z.sub.1 and Z.sub.2 is a methyl group or a methoxy group, and its salt.

Thiophenesulfonamide compounds, herbicidal compositions containing them,

A sulfonamide compound and a salt thereof is represented by the following general formula: ##STR1## wherein each of X.sub.1, X.sub.2, and X.sub.3 independently represents a hydrogen atom or a halogen atom, each of Y.sub.1, Y.sub.2, and Y.sub.3 independently represents a halogen atom, and R represents a methyl group or a methoxy group, and is effective as an active ingredient of a herbicidal composition.
