An agrochemical composition comprising (i) an agrochemical active ingredient; and (ii) a graft polymer comprising (A) a polymer backbone as a graft base, wherein said polymer backbone is obtainable by polymerization of at least one alkylene oxide selected from the group of C2- to C10-alkylene oxides, preferably C2- to C5-alkylene oxides, such as ethylene oxide, 1,2-propylene oxide, 1,2-butylene oxide, 2,3-butylene oxide, 1,2-pentene oxide or 2,3-pentene oxide; and optionally at least one polyol selected from the group of C2- to C14-polyols or at least one polyamine selected from the group of C2- to C14-polyamines; and (B) polymeric sidechains grafted onto the polymer backbone (A), wherein said polymeric sidechains (B) are obtainable by polymerization of monomers comprising at least one vinyl ester monomer (B1) in the presence of the polymer backbone (A). It was found that the graft polymer of the inventive composition is suitable as a dispersant for pesticides in agrochemical compositions. Moreover, the graft polymer typically exhibits a suitably high degree of biodegradability.
