The present invention provides a composition comprising a) at least 1 % by weight of copolymer synthesized from monomers M comprising i) at least one ethylenically unsaturated monomer M1 containing sulfonic acid groups, ii) at least one monomer M2 selected from C1-C4 alkyl (meth)acrylates, and iii) at least one monomer M3 selected from C6-C22 alkyl (meth)acrylates; b) at least 10% by weight of organic solvent; c) not more than 10% by weight of water; d) at least 1 % by weight of water-insoluble pesticide; and e) at least 1 % by weight of nonionic surfactant. Further provided is a process for preparing this composition by contacting the copolymer, the organic solvent, the water-insoluble pesticide, and the nonionic surfactant. The invention relates additionally to the agrochemical application of the composition.
