Abstract: 1H-Pyrazole compounds (I) or their salts are new. 1H-Pyrazole compounds of formula (I) or their salts are new. Het : a 5 membered heteroaryl residue with two heteroatoms, where one of the heteroatom is in the ring is N and the other is S, and the N in the ring is in 1,3-position to the ring-C-atom, which is bonded to the pyrazole residue; R 1>H or hydrolysable residue; either R 2>, R 3>H, halo or (1-6C)-alkyl (which is optionally substituted by at least one halo, (1-4C)-alkoxy, (1-4C)-alkylthio or (1-4C)-haloalkoxy); or R 2>R 3>C : saturated or partially unsaturated 3-6C-carbocyclic ring (optionally substituted by at least one halo or (1-4C)-alkyl); R 4>(1-6C)-alkyl, (2-6C)-alkenyl or (2-6C)-alkynyl (all optionally substituted by at least one halo, CN, OH, (1-4C)-alkoxy, (1-4C)-haloalkoxy, (1-4C)-alkoxy-(1-4C)-alkoxy or (1-4C)-alkylthio), (3-9C)-cycloalkyl (optionally substituted by halo, CN, (1-4C)-alkyl, (1-4C)-haloalkyl, (1-4C)-alkoxy, (1-4C)-alkoxy-(1-4C)-alkoxy or (1-4C)-alkylthio), H, halo or CN, or (5-9C)-cycloalkenyl, (5-9C)-cycloalkynyl (optionally substituted by at least one halo, (1-4C)-alkyl, (1-4C)-haloalkyl, (2-4C)-alkenyl, (2-4C)-alkynyl, (1-4C)-alkoxy, (1-4C)-haloalkoxy or (1-4C)-alkylthio), phenyl (optionally substituted by at least one halo, CN, nitro, carboxy, (1-4C)-alkyl, (1-4C)-haloalkyl, (2-4C)alkenyl, (2-4C)-alkynyl, (1-4C)-alkoxy, (1-4C)-haloalkoxy, (1-4C)-alkoxy-(1-4C)-alkoxy, (1-4C)-alkylthio, (1-4C)-alkanoyl, (1-4C)-haloalkanoyl, [(1-4C)-alkoxy]-carbonyl or [(1-4C)-haloalkoxy]-carbonyl), (1-6C)-alkanoyl (optionally substituted by at least one halo, CN, (1-4C)-alkoxy, (1-4C)-haloalkoxy, (1-4C)-alkoxy-(1-4C)-alkoxy or (1-4C)-alkylthio), (3-6C)-cycloalkyl (optionally substituted by halo, CN, (1-4C)-alkyl or (1-4C)-haloalkyl), [(1-4C)-alkoxy]-carbonyl (optionally substituted by at least one halo, CN, (1-4C)-alkoxy, (1-4C)-haloalkoxy, (1-4C)-alkoxy-(1-4C)-alkoxy or (1-4C)-alkylthio) or [(3-9C)-cycloalkoxy]-carbonyl (optionally substituted by at least one halo, (1-4C)-alkyl, (1-4C)-haloalkyl, (2-4C)-alkenyl, (2-4C)-alkynyl, (1-4C)-alkoxy, (1-4C)-haloalkoxy or (1-4C)-alkylthio); R 5>6-30C, preferably 6-20C-aryl (optionally substituted), or heteroaryl with 1-4 heteroatoms of N, O or S (optionally substituted by a substituent containing 1-30C-atoms) or (R 6>) n; and R 6>(3-9C)-cycloalkyl or (5-9C)-cycloalkenyl (both optionally substituted by halo, (1-4C)-alkyl or (1-4C)-haloalkyl), halo, OH, amino, nitro, carboxy, CN, carbamoyl, (1-6C)-alkyl, (1-6C)-haloalkyl, (1-4C)-alkoxy-(1-4C)-alkyl, (1-4C)-alkylthio-(1-4C)-alkyl, mono or di-[(1-4C)alkyl]-aminoalkyl, hydroxy-(1-4C)-alkyl, (2-6C)-alkenyl, (2-6C)-haloalkenyl, (2-6C)-alkynyl, (2-6C)-haloalkynyl, (1-6C)-alkoxy, (1-6C)-haloalkoxy, (1-4C)-alkoxy-(1-4C)-alkoxy, (1-6C)-alkylthio, (1-6C)-haloalkylthio, [(1-6C)-alkoxy]-carbonyl, [(1-6C)-haloalkoxy]-carbonyl, (1-6C)-alkanoyl, (1-6C)-haloalkanoyl, mono- or di-[(1-4C)alkyl]-aminocarbonyl, mono- or di-[(1-6C)-acyl]-amino, mono- or di-[(1-4C)alkyl]-(1-6C)-haloalkylsulfinyl, (1-6C)-alkylsulfonyl, or (1-6C)-haloalkylsulfonyl, when n is 1 or greater than 1; and n : 0-2.
