Abstract

An object of the present invention is a process for the preparation of particles which comprise two agrochemical active ingredients in amorphous form, where a melt comprising the two molten agrochemical active ingredients is emulsified in an aqueous solution and cooled. A further object is the use of an agrochemical active ingredient for inhibiting the crystallization of another agrochemical active ingredient in a preparation process for particles which comprise the two agrochemical active ingredients in amorphous form, where a melt comprising the two molten agrochemical active ingredients is emulsified in an aqueous solution and cooled. A further object is particles which comprise two agrochemical active ingredients in amorphous form. The use in plant protection is also described.
