Abstract: Use of a mixture a) of a hydroxy-terminated polyether of the block structure (A) (EO)x1?-(PO)y1-(EO)x1?, where y1 is 40 to 70 and (x1?+x1?) is 30-60 and (x1?+x1?)/y1 is less than 1 (component A), and b) of a hydroxy-terminated polyether of the block structure (B) (EO)x2?-(PO)y2-(EO)x2?, where y2 is 15 to 55 and (x2?+x2?) is 2-50 and (x2?+x2?)/y2 is less than 1 (component B), where (x1?+x1?)/y1 is >(x2?+x2?)/y2, for solubilizing sparingly water-soluble active ingredients, which have a solubility in water of not more than 5 g/l at 25° C. and 0.1013 MPa, in aqueous formulations.

Abstract: The present invention relates to a method for preparing a tank mix, which comprises the step of contacting a pesticide formulation, water, and a tank mix adjuvant which comprises a polypropylene glycol and a triblock polymer comprising at least one polyethyleneoxide moiety and at least one polypropyleneoxide moiety; to the tank mix adjuvant; to a pesticide formulation comprising the tank mix adjuvant: to a method of controlling phytopathogenic fungi and/or undesired vegetation and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the tank mix is allowed to act on the respective pests, their environment or the plants to be protected from the respective pest, on the soil and/or on undesired plants and/or the crop plants and/or their environment, and to a use of the tank mix adjuvant or reducing the wind drift of a pesticide formulation.
