Abstract

Co-crystals comprising
(I) pyrimethanil; and (II) dithiine tetracarboximide of the formula (I)

First claim

1 - 12 . (canceled)

13 . Co-crystals comprising
(I) pyrimethanil; and (II) dithiine tetracarboximide of the formula (I)

14 . The co-crystals of claim 13 , wherein the molar ratio of pyrimethanil and dithiine tetracarboximide of the formula (I) is from 2:1 to 1:2.

15 . The co-crystals of claim 14 , wherein the molar ratio of pyrimethanil and dithiine tetracarboximide of the formula (I) is from 1.5:1 to 1:1.5.

16 . The co-crystals of claim 13 , having a melting point in the range of 125 to 135°.

17 . The co-crystals claim 13 , which, in an X-ray powder diffractogram at 25° C. and Cu radiation, shows at least three of the following diffraction lines, given as 2θ values: 10.19±0.2°, 12.66±0.2°, 13.54±0.2°, 14.78±0.2°, 17.50±0.2°, 17.86±0.2°, 26.41±0.2°, 27.83±0.2°.

18 . A process for the preparation of the co-crystals of claim 13 , comprising the following steps:
i) suspending pyrimethanil and dithiine tetracarboximide of the formula (I) in water, ii) evaporating the solvent to form the co-crystals.

19 . A process for the preparation of the co-crystals of claim 13 , comprising the following steps:
i) suspending pyrimethanil and dithiine tetracarboximide of the formula (I) in a mixture of water and a polar organic solvent, ii) evaporating the solvent to form the co-crystals.

20 . An agricultural formulation comprising the co-crystals of claim 13 .

21 . A method for controlling pests and/or improving the health of plants, wherein the pest, their habitat, breeding grounds, their locus or the plants to be protected against such pest, the soil or plant propagation material are treated with an effective amount of the co-crystals of claim 13 .

22 . A method for controlling pests and/or improving the health of plants, wherein the pest, their habitat, breeding grounds, their locus or the plants to be protected against such pest, the soil or plant propagation material are treated with an effective amount of the agricultural formulation of claim 20 .

23 . A method for improving the health of plants, wherein the plant, the locus where the plant is growing or is expected to grow or plant propagation material from which the plant grows is treated with an effective amount of the co-crystals of claim 13 .

24 . A method for improving the health of plants, wherein the plant, the locus where the plant is growing or is expected to grow or plant propagation material from which the plant grows is treated with an effective amount of the agricultural formulation of claim 20 .

25 . A method for protection of plant propagation material from pests comprising contacting the plant propagation materials with an effective amount of the co-crystals of claim 13 .

26 . A method for protection of plant propagation material from pests comprising contacting the plant propagation materials with an effective amount of the agricultural composition of claim 20 .

27 . A plant propagation material treated with the co-crystals of claim 13 in an amount of from 0.01 g to 10 kg per 100 kg of plant propagation materials.
