USE OF A DITHIINO-TETRACARBOXAMIDE FOR THE PROTECTION OF HARVESTED PRODUCTS AGAINST PHYTOPATHOGENIC FUNGI

摘要

The present invention relates to methods for the protection of harvested fruits, cutflowers or vegetables against decay caused by certain storage diseases or disorders expressed in storage conditions, which fruits, cutflowers or vegetables have been treated pre-harvest with dithiino-tetracarboximides for formula (I). In particular the invention relates to the application of dithiino-tetracarboximides of formula (I) before harvest to protect harvested fruit, cutflowers or vegetables against phytopathogenic fungi.

1. A dithiino-tetracarboxiniide of formula (I) in which R1 and R2 are identical or different and represent hydrogen, C1-C8-alkyl which is optionally monosubstituted or polysubstituted by halogen, —OR3, —COR4, or represent C3-C7-cycloalkyl which are optionally monosubstituted or polysubstituted by halogen, C1-C4-alkyl or C1-C4-haloalkyl, or represent aryl or aryl-(C1-C4-alkyl), each of which is optionally monosubstituted or polysubstituted by halogen, C1-C4-alkyl, C1-C4-haloalkyl, —COR4 or sulphonylamino, R3 represents hydrogen, C1-C4-alkyl, C1-C4-alkylcarbonyl, or represents aryl which is optionally monosubstituted or polysubstituted by halogen, C1-C4-alkyl or C1-C4-haloalkyl, R4 represents hydroxyl, C1-C4-alkyl or C1-C4-alkoxy, n represents 0 or 1, and/or an agrochemically acceptable salt thereof, capable of being used to protect a fruit, cutflower and/or vegetable against phytopathogenic fungi, wherein the dithiino-tetracarboximide of formula (I) and/or salt thereof has been applied pre-harvest thereto.
