A substituted (4-bromopyrazol-3-yl) benzazole of the formula I, where: R1 is C1-C4-alky; R2 is C1-C4-haloalkoxy or C1-C4-alkylsulfonyl; R4 is hydrogen or halogen; R5 is halogen; Z is a group -N=C(XR6)-O- or -N=C(XR6)-S- which may be attached to Α via the nitrogen, oxygen or sulfur; X is a chemical bond, oxygen or sulfur; R6 is C1-C6-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, C1-C4-alkoxy-C1-C4-alkyl, (C1-C4-alkoxy) carbonyl-C1-C4-alkyl, C3-C8-cycloalkyl, phenyl, phenyl-C1-C4-alkyl, 3- to 7-membered heterocyclyl or if X is a chemical bond, R6 may also be amino or halogen; and the agriculturally useful salts of these compounds I, for use as herbicides or for the desiccation/defoliation of plants. |
