Abstract

The present invention provides active ingredients for agrochemical formulations, as well as the production processes therefor. The active ingredient of the invention is a dry, solid ammonium salt of gluphosinate, 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. The production process of said active ingredient comprises a solid/liquid/solid reaction between a solid ammonium salt and solid gluphosinate acid, both solids being dispersed in an organic liquid medium. The products of the invention are highly water-soluble and are useful for controlling crop weeds.
