A B S T R A C T New 3-substituted 1-azolyl-3-methyl-1-phenoxy- butan-2-ones and -ols of the general formula Image in which Az represents 1,2,4-triazol-1-yl, 1,2,4-triazol- 4-yl or imidazol-1-yl, B represents the keto group or the CH(OH) group, Y represents oxygen or sulphur, R represents halogenoalkyl, optionally substituted phenyl or optionally substituted benzyl, or provided Y represents sulphur, may represent alkyl and X1, X2 and X3 are selected independently and each represent hydrogen, halogen, alkyl, halogenoalkyl, alkoxy, alkylthio, alkylsulphonyl, nitro, cyano, alkoxycarbonyl or optionally substi?uted phenyl, are obtained if halogenoether ketones are reacted with 1,2, 4-triazole or imidazole in the presence of a diluent and of an acid-binding agent, and, if appropriate, the keto derivatives thus obtained are reduced. The compounds, as such or as their acid-addition salts or metal-salt complexes, have fungicidal activity, for example against those fungi which cause powdery mildew diseases or cause rice diseases.
