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.

Diaryl ethers and processes for their preparation and herbicidal and desiccant compositions containing them

Diaryl ether compounds useful in the control of weeds are described. An exemplary compound is represented by the general formula (I):

A novel N-phenylcarbamate compound or its salt where possible, which is useful as the active ingredient of a biocidal composition for control of harmful organisms, is represented by the following general formula (I): ##STR1## wherein R.sup.1 is unsubstituted or substituted alkyl; R.sup.2 is H, unsubstituted or substituted alkyl, alkenyl, alkynyl or cycloalkyl, or --COX.sup.1 wherein X.sup.1 is unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl or alkoxy; Z is --CH.sub.2 S--, --SCH.sub.2 --, --CH.sub.2 O--, --OCH.sub.2 --, --CH.sub.2 CH.sub.2 --, --CH.dbd.CH--, --C.tbd.C--, --CH.sub.2 SO--, --CH.sub.2 SO.sub.2 --, --CH.sub.2 SCH.sub.2 --, or --CH.sub.2 O--N.dbd.C(R.sup.4)--; R.sup.3 is unsubstituted or substituted phenyl, pyridyl, benzothiazolyl, benzoxazolyl, benzimidazolyl, imidazopyridyl, naphthyl, pyrimidinyl, thienyl, furyl, thiazolinyl, oxazolinyl, pyrazinyl, thiazolyl, oxazolyl, imidazolyl, pyrazolyl, quinolyl, indolyl, pyrrolyl, benzofuryl, benzothienyl, indanyl, tetrahydronaphthyl, dihydrobenzofuryl, dihydrobenzothienyl, benzoxazinyl, benzothiazinyl or benzoyl.

N-phenylcarbamate compound, process for preparing the sasme and biocidal

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.
