    摘要： The invention relates to a process for the preparation of finely divided suspensions by melt emulsification, comprising at least one substance with a melting temperature above room temperature, comprising the following steps:(a) passing at least one preemulsion, comprising one continuous phase and one disperse phase, to a rotor-stator machine, a rotor-rotor machine or to a continuous and/or disperse phase;(b) optionally adding one or more further components to the at least one preemulsion in the rotor-stator machine;(c) emulsifying the at least one preemulsion with mechanical shear and/or elongation and/or turbulence at a temperature which is at most 10 K above the melting temperature of the at least one substance with a melting temperature above room temperature, or at a temperature which is at least 10 K below and at most 10 K above the glass transition temperature or the melting temperature, if the substance with a melting temperature above room temperature is a polymer, for producing a finely divided emulsion;(d) cooling the finely divided emulsion to produce a finely divided suspension;where the disperse phase fraction at least in step (c) is in the range from 85% to 99.5%.

    摘要： The present invention relates to an aqueous dispersion comprising solid pesticide particles with a particle size of below 10 μm and a saccharide which is dissolved in the aqueous phase. The invention furthermore relates to a process for the preparation of a dispersion according to the invention by bringing a pesticide and a saccharide, which is a monosaccharide, a disaccharide or a mixture of mono- and disaccharide, into contact and dispersing them. A further subject matter relates to the use of a saccharide for slowing down the particle growth of pesticide particles with a particle size of up to 10 μm in aqueous dispersion, to the use of the dispersion or the solid composition for controlling phytopathogenic fungi and/or undesired vegetation and/or undesired attack by insects or mites and/or for regulating the growth of plants. Finally, the present invention also relates to seed, dressed with the dispersion or the solid composition.
