Abstract

The present invention relates to the use of dithiine-tetracarboximide compounds of formula I as defined in the description, and the N-oxides, and salts thereof for combating harmful fungi and seed coated with at least one such compound. The invention also relates to novel dithiine-tetracarboximides, processes and intermediates for preparing these compounds and also to compositions comprising at least one such compound.

First claim

The invention claimed is:

1. A method for combating harmful fungi, comprising:
treating the fungi or the materials, plants, the soil or seeds to be protected against fungal attack with an effective amount of at least one compound of formula I

wherein:
X is O;
k is zero;
R 1 is C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl,
R 2 is C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl;

or the N-oxide or the agriculturally acceptable salt thereof.

2. The method of claim 1 , wherein R 2 is identical to R′.

3. Seed coated with at least one compound of formula I,

wherein:
X is O;
k is 0;

R 1 is C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl,
R 2 is C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl;
or an N-oxide or an agriculturally acceptable salt thereof,
in an amount of from 0.1 g to 10 kg per 100 kg of seed.

4. A compound of formula I

wherein:

X is O;
k is zero;
R 1 is C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl,
R 2 is C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl,
except for 2,6-diallyl[1,4]dithiino[2,3-c;5,6-c′]dipyrrole-1,3,5,7-tetraone;
and an N-oxide or an agriculturally acceptable salt thereof.

5. The compound of claim 4 , wherein R 2 is identical to R′.

6. Compounds of formula V

wherein

R 1 is C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl,
R 2 is C 2 -C 6 -alkenyl or C 2 -C 6 -alkynyl;
except 3,7-bis-[(Z)-allylimino]-3H,7H-[1,4]dithiino[2,3-c;5,6-c′]difuran-1,5-dione.

7. An agrochemical composition wherein said composition comprises a solvent or solid carrier and at least one compound of formula I, as defined in claim 4 .

8. The composition according to claim 7 , comprising additionally a further active compound.
