1. A method for improving compatibility of
(i) a first aqueous concentrate herbicidal composition that comprises one to a plurality of salts of glyphosate at a total glyphosate a.e. concentration not less than about 360 g/l, wherein (a) the glyphosate is in anionic form accompanied by low molecular weight non-amphiphilic cations in a total molar amount of about 110% to about 120% of the molar amount of glyphosate; and (b) a major amount to substantially all of the low molecular weight non-amphiphilic cations are potassium cations; and
(ii) a second aqueous concentrate herbicidal composition that comprises one to a plurality of salts of a phenoxy-type herbicide
when admixed with water to form a tank-mix composition, the method comprising adding a base in an amount sufficient to raise pH of the tank-mix composition to at least about 4.8.
