Abstract

The present invention relates to a method of applying an aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b), to plants or plant parts. Furthermore, the invention relates to an aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b). It furthermore relates to the use of the dispersion for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insect or mites and/or for regulating the growth of plants, by allowing the dispersion to act on the respective pests, their environment and/or the plants to be protected from the respective pest, on plant parts, on the soil and/or on undesired plants and/or on the useful plants and/or their environment.

First claim

1 - 15 . (canceled)

16 . A method for controlling phytopathogenic fungi and/or undesired attack by insect or mites and/or for regulating the growth of plants, comprising applying an aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b), to plants or plant parts, wherein the diisocyanate (a) comprises not more than 5% by weight of aromatic diisocyanate and at least 95% by weight of aliphatic diisocyanate, in each case based on the diisocyanate (a).

17 . The method according to claim 16 , wherein the diol (b) comprises diols (b1) and (b2), of which
b1) 10 to 100 mol %, based on the total amount of the diols (b), have a molecular weight of from 500 to 5000, and b2) 0 to 90 mol %, based on the total amount of the diols (b), have a molecular weight of from 60 to 500 g/mol.

18 . The method according to claim 16 , wherein the diol (b1) is a polyester polyol, obtainable by reacting dihydric alcohols with divalent carboxylic acids.

19 . The method according to claim 16 , wherein the diisocyanates (a) are compounds of the formula X(NCO) 2 , where X is an aliphatic hydrocarbon radical having 4 to 12 carbon atoms or a cycloaliphatic hydrocarbon radical having 6 to 15 carbon atoms.

20 . The method according to claim 16 , wherein the diisocyanate comprises 1-isocyanato-3,5,5-trimethyl-5-isocyanatomethylcyclohexane (IPDI), and/or bis(4-isocyanatocyclohexyl)methane (HMDI).

21 . The method according to claim 16 , wherein the dispersion comprises 10 to 250 g/l of a film-forming adjuvant.

22 . The method according to claim 16 , wherein the weight ratio of pesticide to polyurethane is in the range of from 1:100 to 1:1.

23 . The method according to claim 16 , wherein the pesticide is a fungicide, preferably from the class of the strobilurins or carboxanilides.

24 . The method according to claim 16 , wherein the dispersion comprises the polyurethane in a concentration of from 50 to 650 g/l.

25 . The method according to claim 16 , wherein the dispersion comprises the pesticide in a concentration of from 0.5 to 100 g/l.

26 . The method according to claim 16 , wherein the plants are grapevines.

27 . The method according to claim 16 , wherein the dispersion is applied to wound areas caused by pruning.

28 . An aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b), to plants or plant parts, wherein the diisocyanate (a) comprises not more than 5% by weight of aromatic diisocyanate and at least 95% by weight of aliphatic diisocyanate, in each case based on the diisocyanate (a).

29 . Plant parts which have been separated from a plant and to which an aqueous, pesticide-comprising dispersion of a polyurethane which is composed of diisocyanates (a) and diols (b), to plants or plant parts, wherein the diisocyanate (a) comprises not more than 5% by weight of aromatic diisocyanate and at least 95% by weight of aliphatic diisocyanate, in each case based on the diisocyanate (a), has been applied.

30 . The plant parts of claim 29 , wherein the diol (b) comprises diols (b1) and (b2), of which
b1) 10 to 100 mol %, based on the total amount of the diols (b), have a molecular weight of from 500 to 5000, and b2) 0 to 90 mol %, based on the total amount of the diols (b), have a molecular weight of from 60 to 500 g/mol.

31 . The plant parts of claim 29 , wherein the diol (b1) is a polyester polyol, obtainable by reacting dihydric alcohols with divalent carboxylic acids.

32 . The plant parts of claim 29 , wherein the diisocyanates (a) are compounds of the formula X(NCO) 2 , where X is an aliphatic hydrocarbon radical having 4 to 12 carbon atoms or a cycloaliphatic hydrocarbon radical having 6 to 15 carbon atoms.

33 . The dispersion of claim 30 , wherein the diol (b) comprises diols (b1) and (b2), of which
b1) 10 to 100 mol %, based on the total amount of the diols (b), have a molecular weight of from 500 to 5000, and b2) 0 to 90 mol %, based on the total amount of the diols (b), have a molecular weight of from 60 to 500 g/mol.

34 . The dispersion of claim 30 , wherein the diol (b1) is a polyester polyol, obtainable by reacting dihydric alcohols with divalent carboxylic acids.

35 . The dispersion of claim 30 , wherein the diisocyanates (a) are compounds of the formula X(NCO) 2 , where X is an aliphatic hydrocarbon radical having 4 to 12 carbon atoms or a cycloaliphatic hydrocarbon radical having 6 to 15 carbon atoms.
