AbstractCompounds of the formula ##STR1## in which: R1 and R2 independently of one anther are hydrogen, halogen, C1 -C3 alkyl, C1 -C2 haloalkyl, C1 -C3 alkoxy or C1 -C3 haloalkoxy; R3 is hydrogen; C1 -C4 alkyl; or C1 -C4 alkyl substituted by halogen, hydroxy or by cyano; cyclopropyl; or cyclopropyl mono- to tri-substituted by methyl and/or by halogen; and R4 is C3 -C6 cycloalkyl or C3 -C6 cycloalkyl mono- to tri-substituted by methyl and/or by halogen, have valuable microbicidal and insecticidal properties. The novel active ingredients can be used in plant protection for preventing an attack on cultivated plants by phytopathogenic microorganisms or by harmful insects, and for controlling these pests.
