Abstract
Abstract N-Acylated N-phenyl-aminotetrahydro-2-furanones of the formula I are valuable fungicidal active substances. They can be used as fungicidal compositions, particularly for combatting 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.
