ABSTRACT OF THE DISCLOSURE N-Acylated N-phenyl-aminotetrahydro-2-furanones of the formula I: Image (I) wherein the R5-moiety stems from alkylthioalkyl, alkoxyalkyl, alkoxyalkoxymethyl, 2-furanyl, 2-tetrahydrofuranyl, 1,2,4-tri- azolylmethyl, 1,2-pyrazolylmethyl or -CH2OR6 in which R6 is a 5- or 6-membered heterocycle having oxygen as hetero atom and wherein the substituents R, R1, R2, R3 and R4 are as defined hereinafter. The compounds 1 are valuable fungicidal active substances. They can be used in fungicidal compositions, part- icularly for combating phytopathogenic fungi, e.g. against downy mildew on potatoes, tomatoes, grape vines and sugar beet and other plants. The novel compounds have a systemic action.
