CA 1184560

A B S T R A C T The invention relates to new 5-aryloxy-5-azolyl- 3,3-dimethylpent 1-ene-1-ones and -ols, a process for their preparation, and their use as fungicides. The compounds of the formula Image (I) in which Ar, Az and B have the meaning given in the des- cription, are obtained when halogenoether-ketones are reacted with 1,2,4-triazole or imidazole in the presence of an acid- binding agent and, if appropriate, in the presence of a diluent, and the resulting keto derivatives of the formula (I) are reduced in a customary manner, according to known methods, if appropriate. The active compounds are suitable for use as plant protection agents, and can be employed with particularly good success for combating those fungi which cause powdery mildew diseases, thus for combating Erysiphe species, Sphaerotheca species and Podosphaera species, and for combating diseases of rice.
