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.

摘要:
The present invention relates to an aqueous composition comprising a) a suspended pesticide which is soluble in water at 20° C. to no more than 10 g/l, b) a salt, and c) a protective colloid, which is a polysaccharide which is substituted by C3-C32-alkylcarbonyl and/or C3-C32-alkylcarbamoyl groups. The invention furthermore relates to a process for the preparation of the composition by bringing a) the pesticide, b) a salt, and c) the protective colloid, into contact with one another. Moreover, it relates to a use of salt for slowing down the particle growth in an aqueous composition comprising the suspended pesticide and the protective colloid.
摘要:
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.
