Claims

1. A composition comprising a pesticide and a copolymer, which contains in polymerized form

an amide (monomer A) containing at least one monomer from N-vinyllactam, Ν-Ci-Ce alkyl acrylamide and N,N-di-Ci-C6 alkyl acrylamide;

a poly(C2-6 alkylene glycol) (meth)acrylate and/or a mono C1-22 alkyl terminated poly(C2-6 al- kylene glycol) (meth)acrylate (monomer B); and

a Ci-Ce alkyl (meth)acrylate (monomer C).

2. The composition according to claim 1 , wherein the copolymer contains

at least 25 wt% monomer A,

at least 1 wt% monomer B, and

at least 5 wt% monomer C,

based on the total amount of monomers.

3. The composition according to claims 1 or 2, wherein the copolymer contains

25 to 85 wt% monomer A,

1 to 40 wt% monomer B,

5 to 50 wt% monomer C, and

up to 15 wt% further monomers D,

wherein the sum of monomers A, B, C and D equals 100 %.

4. The composition according to any of claims 1 to 3, wherein monomer A comprises N-vinyl- pyrrolidone and N-C1-C6 alkyl acrylamide.

5. The composition according to any of claims 1 to 4, wherein monomer B is a mono C1-22 al- kyl terminated poly(ethylene glycol) (meth)acrylate.

6. The composition according to any of claims 1 to 5, wherein monomer C is methyl methacry- late.

7. The composition according to any of claims 1 to 6, wherein the pesticide has a solubility in water of up to 10 g/l.

8. The composition according to any of claims 1 to 7, containing up to 10 wt% water.

9. The composition according to any of claims 1 to 8, wherein the pesticide is present in dissolved form.

10. The composition according to any of claims 1 to 9, wherein the weight ratio of the copolymer to the pesticide is situated in the range from 10 : 1 to 1 : 10.

The composition according to any of claims 1 to 10, wherein the composition contains an organic solvent which contains at least one amide of the formula (I)

R1-C(0)N(R2)2 (I)

where R1 is Cs-C-ig-alkyl, and R2 is Ci-C4-alkyl, and optionally a further solvent selected from an alkyl alkanoate and an hydrocarbon oil.

12. The composition according to any of claims 1 to 1 1 comprising

2-20% by weight of copolymer;

40-95% by weight of organic solvent;

not more than 3 wt% by weight of water;

1 -25% by weight of the water-insoluble pesticide; and

3-50% by weight of nonionic surfactant.

13. A process for preparing the composition according to any of claims 1 to 13 by contacting the pesticide and the copolymer.

A method for controlling phytopathogenic fungi and/or unwanted plant growth and/or unwanted insect or mite infestation and/or for regulating the growth of plants, wherein the composition according to any of claims 1 to 13 is caused to act on the respective pests, their habitat or the plants to be protected from the respective pest, to the soil and/or to unwanted plants and/or the crop plants and/or their habitat.

A plant propagation material comprising the composition according to any of claims 1 to 13.
