Abstract

Novel 3-acyloxy-4-keto-.beta.-ionone derivatives of the formula I ##STR1## wherein Z is either the radical ##STR2## in which R.sub.1 represents C.sub.2 -C.sub.5 alkyl, C.sub.1 -C.sub.5 alkoxy-C.sub.1 -C.sub.5 alkyl having a maximum number of 6 carbon atoms, cyclopropyl or cyclopropyl which is substituted by methyl or by halogen or represents the radical ##STR3## wherein R.sub.2 represents C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.5 alkoxy-C.sub.1 -C.sub.5 alkyl having a maximum number of 6 carbon atoms, cyclopropyl or cyclopropyl which is substituted by methyl or by halogen and X represents either oxygen or sulphur, and ##STR4## display very effective microbicidal activity. They can especially be used in microbicidal compositions to control plant-pathogenic microorganisms, preferably fungi of the order Oomycetes.
