Novel herbicidally active N-Phenyl-azoles The invention relates to novel phenyl substituted pyrazoles, 4,5,6,7tetrahydro-indazoles, 2,4,5,6-tetrahydro-cyclopenta¢c!pyrazoles, octahydroimidazo¢1,5-a!pyridin-1,3-diones, hexahydro-1H-pyrrolo¢1,2-c!-imidazol-1,3-diones, hexahydro-1H-1,2,4-triazolo¢1,2-a!pyridazin-1,3-diones and tetrahydro-1H,5H-pyrazolo¢1,2-a!¢1,2,4!triazol-1,3-diones which have phenyl-substituted in the 2-position, herbicidal activity. It furthermore relates to agrochemical compositions, which contain these compounds, to their use for controlling undesirable plant-growth and for processes for the preparat1on of the compounds according to this invention. The novel N-Phenyl-azoles correspond to the formula I (I), where in , or ; R1 is hydrogen or halogen; R2 is halogen; A is a straight-chain or branched C1-C4-alkylene chain; n is zero or 1; - ? Q is -S(O)m-R3; di-C1-C4,-alkylamino; a 5- or 6-membered heterocyclus, that is bound via a carbon or nitrogen atom and which contains 1 to 3 hetero-atoms selected from the group consisting of N, O and S, which heterocycles can be fused to a benzene ring and mono- or disubstituted by halogen, C1-C4-alkyl, C1-C3-haloalkyl, C1-C3-alkoxy, C1-C3-halo-alkoxy, C1-C3-dialkylamino, hydroxy or carboxyl; R3 is C1-C10-alkyl; or ; m is zero, 1 or 2; R4 is C1-C4-alkyl, halogen or C1-C4-alkoxy; p is zero 1, 2, or 3; X is hydrogen, halogen or C1-C4-alkyl; Y is C1-C4-alkyl; or X and Y form together a -(CH2)q-chain, which is optionally mono- or disubstituted by methyl; q is three or four; and Z is halogen, methyl, C1-C6-alkoxy or C1-C6-alkylthio; under inclusion of the salts of these azoles with acids, bases and complex-building substances.
