Abstract: 3-Phenyl-oxazolidine-2,4-dione derivatives can be halogenated directly, without splitting of the heterocyclic ring. The products thus obtained have a fungicidal action which is substantially wider than that of compounds hitherto known.

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.
