The invention relates to new modifications of abscisic acid, to liquid compositions of abscisic acid and to their use in agrochemical applications. The modifications and compositions of the invention contain abscisic acid in the form of a solvate with at least one N-alkyl pyrrolidone, wherein the N-alkyl group has 3 to 6 carbon atoms. These solvates enable formulations with high concentrations of abscisic acid.
