Abstract
Abstract Acylated phenylaminotetrahydro-2-furanones of the formula I disclosed herein, which have a systemic action, are suggested as novel microbicides. They can be used in the form of pesticidal compositions in particular for combating phytopathogenic fungi, or for preventing fungus infections on cultivated plants.
