摘要

The invention relates to plant protection agents which contain a triazole compound of the formula I IMAGE (I) in which Z denotes halogen, nitro, cyano, trifluoromethyl, (substituted) alkyl, (substituted) alkoxy, (substituted) alkylthio, (substituted) cycloalkyl, (substituted) phenyl or (substituted) phenoxy, Y denotes H, (substituted) alkyl, alkenyl, alkinyl or (substituted) cycloalkyl, X denotes hydroxyl, alkyl, cycloalkoxy, phenoxy, alkenyloxy, alkinyloxy, (substituted) alkoxy, (substituted) alkylthio or a radical of the formulae IMAGE and n denotes 0, 1, 2 or 3, and salts thereof, and to new compounds of the formula I as defined above, Y denoting CCl3 or CHCl2 in the event that X denotes (C1-C4)-alkyl, and compounds in which (a) Y denotes H, (Z)n denotes H, 4-Cl, 4-CH3, 2-OCH3, 4-OCH3 or 4-OC2H5 and X denotes OH, OCH3 or OC2H5, (b) Y denotes CH3, (Z)n denotes 4-NO2, 4-OCH3, 2-Cl, 4-Cl, 2-OCH3-4-NO2 or 2-CH3-4-NO2 and X denotes OH or OC2H5 and (c) Y denotes C2H5 or CH(CH3)2, (Z)n denotes H and X denotes OCH3 being excepted. The compounds of the formula I are suitable for protecting crop plants from the phytotoxic side-effects of plant protection agents.
