Abstract
The present invention provides active ingredients and herbicide formulations, as well as the production processes therefor. The active ingredient of the invention is a dry, solid ammonium salt of glyphosate, having high purity (95 to 100%) and low humidity (<1.0% m/m), and is useful as “technical salt” for the preparation of dry, solid, and water-soluble herbicide formulations of the invention. The production process of said active ingredient comprises a solid/liquid/solid reaction between a solid ammonium salt and solid glyphosate acid, both solid being dispersed in an organic liquid medium. The products of the invention are highly water-soluble and are useful for controlling crop weeds.
Claims17
A process for the preparation of solid salt of ammonium glyphosate characterized by comprising a solid/liquid/solid reaction, wherein a solid ammonium salt and a solid acid glyphosate are dispersed in a organic liquid and thereby react to form the solid salt of ammonium glyphosate.
A solid and water-soluble active ingredient comprising an ammonium salt of glyphosate having purity equal to or greater than 95% w/w and a humidity equal to or lower than 1%.
A solid and water-soluble herbicide formulation, comprising:
- at least one ammonium salt of glyphosate having purity equal to or greater than 95% w/w;
- and
- at least one dry, solid adjuvant.
A process for the preparation of a solid, water-soluble herbicide formulation, comprising mixing:
- at least one ammonium salt of glyphosate having purity equal to or greater than 95% w/w;
- and
- at least one dry, solid adjuvant.
A process for controlling weeds comprising the application, to the plant culture to be protected, of an agrochemical comprising as active ingredient the ammonium salt of glyphosate having purity equal to or greater than 95% w/w.
A method for preparing an agrochemical for controlling weeds, comprising adding to the agrochemical an active ingredient comprising the ammonium salt of glyphosate having purity equal to or greater than 95% w/w.
