Abstract

The present invention relates to a composition comprising an agrochemical active substance and a copolymer which comprises an N-vinylcarboxamide and a diallyldialkylammonium salt incorporated into the polymer. The invention furthermore relates to a method of preparing this composition; to the use of this composition for dispersing agrochemical active substances; to a method of controlling phytopathogenic fungi and/or undesired plant growth and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the composition is allowed to act on the respective pests, their environment or the crop plants to be protected from the respective pest, on the soil and/or on undesired plants and/or on the crop plants and/or on their environment; and furthermore to seed comprising the composition.

Claims

1-15. -15. (canceled)

16. A composition comprising an agrochemical active substance and a copolymer which comprises 20 to 95% by weight of an N-vinylcarboxamide and 1 to 70% by weight of a diallyldialkylammonium salt incorporated into the polymer, based on the total amount of the copolymerized monomers, wherein the N-vinylcarboxamide is an N-vinyl-C₁-C₁₈-alkylcarboxamide and/or an N-vinyl-N—

(C₁-C₁₂-alkyl)-C₁-C₁₈-alkylcarboxamide.

17. The composition according to claim 16, wherein the agrochemical active substance comprises a water-insoluble first pesticide.

18. The composition according to claim 16, wherein the agrochemical active substance comprises a) a water-insoluble first pesticide and b) a water-soluble second pesticide or water-soluble inorganic fertilizer.

19. The composition according to claim 16, comprising at least 5% by weight of the second pesticide or of the inorganic fertilizer.

20. The composition according to claim 16 in the form of an aqueous composition, wherein the water-insoluble first pesticide is present in the form of suspended particles.

21. The composition according to claim 16, comprising from 1 to 20% by weight of the copolymer.

22. The composition according to claim 16, wherein the copolymer is a random copolymer.

23. The composition according to claim 16, where diallyldialkylammonium salt corresponds to the formula (I)

24. The composition according to claim 16, wherein the N-vinylcarboxamide is N-vinyl-N-methylformamide, N-vinylformamide, N-vinyl-N-ethylformamide, N-vinyl-N-propylformamide, N-vinyl-N-isopropylformamide, N-vinyl-N isobutylformamide, N-vinylacetamide, N-vinyl-N-methylacetamide, N-vinylpropionamide, or N-vinyl-N-methylpropionamide, and mixtures thereof.

25. The composition according to claim 16, comprising 40 to 95% by weight of N-vinylcarboxamide, based on the total mass of all monomers of the copolymer.

26. The composition according to claim 16 comprising 5 to 50% by weight of diallyldialkylammonium salt, based on the total mass of all monomers of the copolymer.

27. A method of controlling phytopathogenic fungi and/or undesired plant growth and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the composition according to claim 16 is allowed to act on the respective pests, their environment or the crop plants to be protected from the respective pest, on the soil and/or on undesired plants and/or on the crop plants and/or on their environment.

28. The method of claim 27, wherein the agrochemical active substance comprises a water-insoluble first pesticide.

29. The method of claim 27, wherein the agrochemical active substance comprises a) a water-insoluble first pesticide and b) a water-soluble second pesticide or water-soluble inorganic fertilizer.

30. The method of claim 27, wherein the composition comprises at least 5% by weight of the second pesticide or of the inorganic fertilizer.

31. The method of claim 27, wherein the composition is in the form of an aqueous composition, wherein the water-insoluble first pesticide is present in the form of suspended particles.

32. The method of claim 27, wherein the composition comprises from 1 to 20% by weight of the copolymer.

33. The method of claim 27, wherein the copolymer is a random copolymer.

34. The method of claim 27, where diallyldialkylammonium salt corresponds to the formula (I)

35. Seed treated with the composition according to claim 16.
