Abstract
Compounds of the formula ##STR1## wherein R.sub.1 is hydrogen or methyl, PA1 R.sub.2 is hydrogen, halogen, OCH.sub.3, SCH.sub.3 or CN, PA1 R.sub.3, R.sub.4, R.sub.5 are each independently of one another hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.2 -C.sub.5 alkoxycarbonyl, C.sub.1 -C.sub.5 alkanoyl, C.sub.1 -C.sub.4 haloalkyl, C.sub.1 -C.sub.4 haloalkoxy, CN, NO.sub.2, or wherein two of those substituents are adjacent to each other and together are a methylenedioxy or difluoromethylenedioxy radical, PA1 K, L, M are each independently of one another CH or N (=nitrogen atom), but at least one of these three substituents is N, and PA1 Y is oxygen or sulfur, are effective microbicides for controlling fungal diseases. They can be used for plant protection by themselves or as formulated compositions.
