<p>N-Acylated N-phenyl-aminotetrahydro-2-furanones of the formula I: (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 5or 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, particularly 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.</p> |
