    Abstract: The present invention relates to liquid pesticide concentrate compositions which comprise at least one organic pesticide compound that is sparingly or even insoluble in water and which upon dilution with water form stable aqueous nanoparticulate formulations. The liquid pesticide concentrate compositions of the invention comprise: a) at least one organic pesticide compound C having a water solubility of not more than 1 g/l at 25° C./1013 mbar, b) at least one organic solvent S having a water solubility at least 10 g/l at 25° C./1013 mbar, and which is capable of dissolving the pesticide compound C, or a mixture of at least one organic solvent S with water, provided that the weight ratio of water to solvent S does not exceed 1:2, c) at least one non-ionic blockcopolymer P comprising at least one polyethyleneoxide moiety PEO and at least one hydrophobic polyether moiety consisting of repeating units selected from C3-C10-alkyleneoxides and styrene oxide, d) optionally one or more non-polymeric surfactants, wherein the weight ratio of the non-ionic blockcopolymer to the organic pesticide compound P:C is from 0.6:1 to 10:1 and wherein the components a), b) and optionally d) make up at least 95% of the composition. The invention also relates to aqueous pesticide compositions which are obtained by diluting the concentrate pesticide compositions of the invention with water and to their use for plant protection.
