Method for preparation of an aqueous glyphosate concentrate composition having mixture of amine salts

A method for preparing a glyphosate herbicidal aqueous concentrate to improve the handling of the concentrate, the method comprising:

• forming a mixture of at least two nitrogen bases, and reacting the mixture of the at least two bases with glyphosate acid to provide an aqueous solution comprising a mixture of glyphosate salts wherein the concentration of glyphosate (based on glyphosate acid equivalent) is at least 500 gae/L, wherein the at least two nitrogen bases are selected from the group consisting of ammonia, C1 to C10alkylamine, di-(C1 to C6 alkyl)amine, tri-(C1 to C6 alkyl)amine, C1 to C10 alkanolamine, C1 to C6 alkyl(C1 to C6alkanol)amines and di-(C1 to C6 alkyl)C1 to C6alkanolamines, wherein the mixture of bases present upon said forming is not a mixture consisting of potassium hydroxide, monoethanolamine and isopropylamine, and wherein the mole ratio of the at least two nitrogen bases:glyphosate acid is in the range of from 0.9:1 to 1.3:1.
