Compounds of formula <IMAGE> wherein R1 is hydrogen, 3-fluorine or 4-fluorine, and R2 is C1-C4alkyl, halo- or hydroxy-substituted C1-C2alkyl, C3-C6cycloalkyl or C3-C6cycloalkyl mono- to tri-substituted by identical or different substituents selected from methyl and halogen, have valuable microbicidal properties. The novel compounds can be used in crop protection for preventing an attack on cultivated plants by phytopathogenic microorganisms and for controlling those pests.
