Solid agroformulations prepared from a melt of pesticide and polyalkoxylate, optionally containing liquid adjuvant complexed with polycarboxylate

Abstract

The present invention relates to a method for a preparation of a solid composition comprising the steps of a) dissolving a premix in a premix-solvent, or melting a premix, wherein the premix contains a pesticide and a nonionic, amphiphilic polyalkoxylate, b) solidifying the premix by removing the premix-solvent, or by cooling, and c) contacting the premix with at least one auxiliary. The invention further relates to a solid composition obtainable by said method; to a method for the preparation of an aqueous tank mix, in which a pesticide is present as suspended particles having a particle size below 1.0 μm, comprising the step of mixing water and a solid composition obtainable by the said method; and to a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants, where a solid composition obtainable by said method is allowed to act on the particular pests, their habitat or the plants to be protected from the particular pest, the soil and/or on undesired plants and/or the useful plants and/or their habitat.

1 . A method for the preparation of a solid composition comprising the steps of
 a) dissolving a premix in a premix-solvent or melting a premix, wherein the premix contains a pesticide and a nonionic amphiphilic polyalkoxylate,   b) solidifying the premix by removing the premix-solvent or by cooling, and   c) contacting the premix with at least one auxiliary.
