The use of substituted imidazoazines of the formula I, where 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, where R<1 >may be unsubstituted or substituted as in the description; R<2>, R<3>. are hydrogen, alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, haloalkynyl, trialkylsilylalkyl, phenyl, phenylalkyl or 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; A, B are N or CR<4>; 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; for controlling phytopathogenic harmful fungi, compositions comprising them, novel imidazoazines and processes for their preparation are described.
