摘要

PESTICIDE COMPOSITION, USE OF THE SAME, AND METHODS TO COMBAT ORGANISMS THAT ARE HARMFUL TO PLANTS, TO PROTECT BODIES FROM ATTACK OR INFESTATION AND TO PROTECT THE SEEDS OF THE PRESENT AFFECTS OR INJURIES liquid pesticide concentrates comprising at least one organic pesticide compound that is sparingly or still insoluble in water and which in 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 solubility in water of at least 10 g / l at 25 C / 1013 mbar, and which is capable of dissolving 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 is not exceeds 1: 2, c) at least one nonionic block copolymer P comprising at least one portion of PEO polyethylene oxide and at least one portion of hydrophobic polyether consisting of selected repeat units of C 3-3 C-alkylene oxides D) and styrene oxide, d) optionally one or more non-polymeric surfactants, wherein the weight ratio of the nonionic block copolymer to the organic pesticide compound P: C is from 0.6: 1 to 10: 1 and wherein components a), b) and opc d) prepare at least 95% of the composition. The invention also relates to aqueous pesticidal compositions which are obtained by diluting the concentrated pesticidal compositions of the invention with water and their use for plant protection.
