Pyrazole derivatives, for use as herbicides, have the formula (I): wherein R represents hydrogen, halogen or methyl; R represents hydrogen, halogen, nitro, methyl, cyano, carboxy, (C1 to C8)-alkoxy or (C1 to C4)-alkoxycarbonyl; R represents hydroxy, amino, (C3 or C4)-alkenyloxy, C3 or C4)-alkynyloxy, (C1 to C4)-alkoxy-(C1 to C4)-alkoxy, (C1 to C4)-alkylthio, (C3 or C4)-alkenylamino, (C1 to C4)-alkylsulfonylamino, (C1 or C2)-alkoxy-(C1 or C2)-alkylamino, -O-N = C-(CH3)2, anilino, benzylamino, morpholino, (C1 to C6)-alkoxy unsubstituted or substituted by (C1 to C4)-alkoxycarbonyl, (C1 to C4)-mono- or di-alkylamino group in which the or each alkyl group is unsubstituted or substituted by hydroxy or carboxy, or -OM wherein M represents an alkali metal, alkaline earth metal, ammonium or (C1 to C4)-alkylammonium; R represents halogen, methyl, (C1 to C4)-alkoxy, -S(O)m-R wherein m is 0, 1 or 2 and R represents (C1 to C4)-alkyl; X represents hydrogen, halogen, (C1 to C4)-alkyl, (C1 to C4)-alkylthio or (C1 to C4)-alkylsulfonyl; and Y represents (C1 to C4)-alkyl or X and Y taken together with the atoms to which they are attached form a cyclopentyl or cyclohexyl ring unsubstituted or substituted with one or more methyl group.
