Abstract

The present invention relates to a composition comprising a water-insoluble pesticide and an alkoxylated polyalkyleneimine. 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. An aqueous composition comprising a water-insoluble pesticide and a nonionic or anionic alkoxylated polyalkyleneimine, wherein the water-insoluble pesticide is present in the form of suspended particles, and wherein the water-insoluble pesticide is soluble in water to no more than 10 g/l at 20°

C.

17. The composition according to claim 16, comprising a watersoluble agrochemical active substance.

18. The composition according to claim 17, comprising at least 5% by weight of the water-soluble agrochemical active substance.

19. The composition according to claim 16, comprising at least 0.1% by weight of the alkoxylated polyalkyleneimine.

20. The composition according to claim 16, wherein the alkoxylated polyalkyleneimine has a molar mass Mw of from 800 to 25 000 g/mol.

21. The composition according to claim 16, wherein the alkoxylated polyalkyleneimine is an ethoxylated and/or propoxylated polyalkyleneimine.

22. The composition according to claim 16, wherein the alkoxylated polyalkyleneimine is an ethoxylated and propoxylated polyalkyleneimine comprising 1 to 50 mol of propylene oxide units and 1 to 50 mol of ethylene oxide units, in each case per mol of NH units.

23. The composition according to claim 16, wherein the alkoxylated polyalkylimine is an ethoxylated and propoxylated polyalkyleneimine comprising 1.5 to 15 mol of propylene oxide units and 10 to 50 mol of ethylene oxide units, in each case per mol of NH units.

24. The composition according to claim 17, wherein the water-soluble agrochemical active substance is a water-soluble pesticide and/or a water-soluble inorganic fertilizer.

25. The composition according to claim 16, wherein the alkoxylated polyalkyleneimine is present in dissolved form.

26. The composition according to claim 16, wherein the water-soluble agrochemical active substance is soluble in water to more than 10 g/l at 20°

C.

27. The composition according to claim 16, comprising from 0.5 to 15% by weight of the alkoxylated polyalkyleneimine.

28. 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.

29. The method of claim 28, wherein said composition comprises a water-soluble agrochemical active substance.

30. The method of claim 29, wherein said composition comprises at least 5% by weight of the water-soluble agrochemical active substance.

31. The method of claim 28, wherein said composition comprises at least 0.1% by weight of the alkoxylated polyalkyleneimine.

32. The method of claim 28, wherein the alkoxylated polyalkyleneimine has a molar mass Mw of from 800 to 25 000 g/mol.

33. The method of claim 28, wherein the alkoxylated polyalkyleneimine is an ethoxylated and/or propoxylated polyalkyleneimine.

34. The method of claim 28, wherein the alkoxylated polyalkyleneimine is an ethoxylated and propoxylated polyalkyleneimine comprising 1 to 50 mol of propylene oxide units and 1 to 50 mol of ethylene oxide units, in each case per mol of NH units.

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