A pyrazole compound of the formula: where: Ris Calkyl, Chaloalkyl, Calkoxy Calkyl, phenyl or pyridyl; Ris a hydrogen atom, Calkyl, Chaloalkyl, Calkoxy or a halogen atom; R, R, Rand Rindependently of one another are a hydrogen atom, Calkyl or Chaloalkyl, with a proviso that at least one of R, R, Rand Ris Calkyl or Chaloalkyl; and L is a hydrogen atom, chlorine atom, SH, benzylthio, chlorosulfonyl, aminosulfonyl, SON&#x2550;C&#x2550;O, SONHCOCHor SONHCONHn-CH. A salt of the compound that is acceptable as an agrochemical. An agrochemical containing the compound or the salt thereof as an active component. A herbicide containing the compound or the salt thereof as an active component.

Pyrazole sulfonylurea compound and herbicide

There is provided a novel herbicide. A pyrazole sulfonylurea compound of formula (1): wherein Ris Calkyl, etc., Ris hydrogen atom, Calkyl, Chaloalkyl, etc., R, R, Rand Rindependently of one another are hydrogen atom, Calkyl, etc., with a proviso that at least one of R, R, Rand Ris Calkyl or Chaloalkyl, X and Y independently of each other are Calkyl, etc., Z is nitrogen atom or methyne, and a salt thereof that is acceptable as an agrochemical; an agrochemical containing at least one of the compound and the salt thereof that is acceptable as an agrochemical as an active component, and a herbicide containing at least one of the compound and the salt thereof that is acceptable as an agrochemical as an active component.

The present invention provides a nitrogen-containing cyclic compound represented by the formula (1): ##STR1## wherein R.sup.1 represents an alkyl group; R represents a hydrogen atom or an alkyl group; X represents an oxygen or sulfur atom or NR.sup.3 ; Q.sup.1 represents a hydrogen atom, or an alkyl, cycloalkyl, alkenyl or alkynyl group or a phenyl, naphthyl or heterocyclic group etc.; Q.sup.2 represents an alkyl, cycloalkyl or alkenyl group, or a phenyl or thienyl group etc.; A.sup.1 represents a carbon or nitrogen atom; A.sup.2 represents CR.sup.2 or NR.sup.2, or an oxygen or sulfur atom, or SO or SO.sub.2 ; A.sup.3 represents a single bond, or an oxygen or sulfur atom, or CR.sup.5 or NR.sup.5) and a herbicide comprising the same, which herbicide exhibits very high herbicidal activity at very low application rate and has selectivity against crops.
