摘要：
The present invention relates to liquid pesticide concentrate compositionswhich comprise at least one organic pesticide compound that is sparingly oreven insoluble in water and which upon dilution with water form stable aqueousnanoparticulate formulations. The liquid pesticide concentrate compositions ofthe invention comprise: a) at least one organic pesticide compound C having awater solubility of not more than 1 g/l at 25~C/1013 mbar, b) at least oneorganic 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 ofat least one organic solvent S with water, provided that the weight ratio ofwater to solvent S does not exceed 1:2, c) at least one non-ionicblockcopolymer P comprising at least one polyethyleneoxide moiety PEO and atleast one hydrophobic polyether moiety consisting of repeating units selectedfrom C3-C10-alkyleneoxides and styrene oxide, d) optionally one or more non-polymeric surfactants, wherein the weight ratio of the non-ionicblockcopolymer to the organic pesticide compound P:C is from 0.6:1 to 10:1 andwherein the components a), b) and optionally d) make up at least 95% of thecomposition. The invention also relates to aqueous pesticide compositionswhich are obtained by diluting the concentrate pesticide compositions of theinvention with water and to their use for plant protection.
