Allophanate derivatives of the formula <IMAGE> in which R1 and R2 can be identical or different and represent an aliphatic, cycloaliphatic, araliphatic or aromatic radical each of which is optionally monosubstituted or polysubstituted by identical or different substituents and R3 represents the radical -XR4 or -NR5R6, wherein R4 represents alkyl, alkoxyalkyl, or aryl which is optionally monosubstituted or polysubstituted by identical or different substituents, X represents oxygen or sulphur and R5 and R6 are identical or different and represent hydrogen, alkyl, or aryl which is optionally monosubstituted or polysubstituted by identical or different substituents, or R5 and R6, together with the nitrogen atom on which they stand, form a saturated heterocyclic radical which is optionally monosubstituted or polysubstituted by identical or different substituents and can be interrupted by further hetero-atoms, which possess fungicidal activity. |
