The use of substituted imidazoazines of the formula I, n n n where n R 1 is alkyl, phenyl, phenylalkyl, naphthyl, anthracenyl, cycloalkyl, 5- or 6-membered hetaryl or 5- or 6-membered heterocyclyl, containing one to three nitrogen atoms and/or one oxygen or sulfur atom or one or two oxygen and/or sulfur atoms, or fused 8- to 12-membered hetaryl or fused 8- to 12-membered heterocyclyl, containing one to four nitrogen atoms and/or one oxygen or sulfur atom or one or two oxygen and/or sulfur atoms, n where R 1 may be unsubstituted or substituted as in the description; n R 2 , R 3 . are hydrogen, alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, haloalkynyl, trialkylsilylalkyl, phenyl, phenylalkyl or n R 2 , R 3 together with the bridging nitrogen atom form a 5- or 6-membered heterocyclic or heteroaromatic ring which may be interrupted by one to three nitrogen atoms and/or one oxygen or sulfur atom or one or two oxygen and/or sulfur atoms and which may be substituted; n A, B are N or CR 4 ; n R 4 , R 5 , R 6 are hydrogen, halogen, cyano, nitro, hydroxyl, alkyl, haloalkyl, cycloalkyl, alkoxy, haloalkoxy, alkylthio, amino, alkylamino, dialkylamino, alkenyl, alkenyloxy, alkynyl or alkynyloxy; n for controlling phytopathogenic harmful fungi, compositions comprising them, novel imidazoazines and processes for their preparation are described. |
