The present invention relates to the use of novel and of known dithiine-tetracarboximides for controlling phytopathogenic fungi, and to methods of controlling phytopathogenic fungi in plant protection, and to plant protection compositions comprising these dithiine-tetracarboximides.
1. A method of controlling phytopathogenic fungi, comprising applying a compound of formula (V)
wherein R 1 and R 2 are identical or different and represent hydrogen; C 1 -C 8 -alkyl which is optionally monosubstituted or polysubstituted by halogen, —OR 3 , or —COR 4 ; C 3 -C 7 -cycloalkyl which is optionally monosubstituted or polysubstituted by halogen, C 1 -C 4 -alkyl, or C 1 -C 4 -haloalkyl; or aryl or aryl-(C 1 -C 4 -alkyl), each of which is optionally monosubstituted or polysubstituted by halogen, C 1 -C 4 -alkyl, C 1 -C 4 -haloalkyl, —COR 4 , or sulphonylamino,
R 3 represents hydrogen, C 1 -C 4 -alkyl, C 1 -C 4 -alkylcarbonyl, or represents aryl which is optionally monosubstituted or polysubstituted by halogen, C 1 -C 4 -alkyl, or C 1 -C 4 -haloalkyl, and
R 4 represents hydroxyl, C 1 -C 4 -alkyl, or C 1 -C 4 -alkoxy.
2. A method of controlling phytopathogenic fungi, comprising applying a compound of formula (V-a)
wherein
R 1a and R 2a are identical or different and represent C 1 -C 8 -alkyl which is substituted by one or more fluorine, —OR 3 a, or —COR 4a ; C 3 -C 7 -cycloalkyl which is optionally substituted by one or more halogen, C 1 -C 4 -alkyl, or C 1 -C 4 -haloalkyl; or aryl-(C 1 -C 4 -alkyl) which is monosubstituted in the alkyl moiety by —COR 4a ,
R 3a represents C 1 -C 4 -alkyl, or represents aryl which is optionally monosubstituted or polysubstituted by halogen, C 1 -C 4 -alkyl, or C 1 -C 4 -haloalkyl, and
R 4a represents hydroxyl, C 1 -C 4 -alkyl, or C 1 -C 4 -alkoxy.
