Claims12
An aqueous herbicidal concentrate composition comprising glyphosate in the form of a mixture of the potassium and ammonium salts, wherein the ratio of glyphosate (acid equivalent) in potassium salt and ammonium salt forms is in the range of from 10:90 to 45:55, wherein the total potassium and ammonium forms of glyphosate are at least 70% of the total glyphosate (acid equivalent) content of the composition and the aqueous concentrate contains glyphosate in an amount of from 300 to 600 g/l (acid equivalent).
A process for preparing an aqueous glyphosate concentrate composition comprising forming an aqueous mixture of glyphosate salts including at least potassium and monoammonium salts, wherein the ratio of glyphosate (acid equivalent) in potassium salt and ammonium salt forms is in the range of from 10:90 to 45:55, wherein the total potassium and ammonium forms of glyphosate are at least 70% of the total glyphosate (acid equivalent) content of the composition and the aqueous concentrate contains glyphosate in an amount of from 300 to 600 g/l (acid equivalent).
