Title compd. (I) wherein the molar ratio of sodium cation to acid substantially 1.5-1 was prepd. by reaction of N-phosphonomethylglycine(II) and base donating 1.25-1.75 mol Na per I. I(5.6 kg/ha postemergence) completely controlled lambsquater, smartweed, quackgrass and barnyardgrass 4 week after application.
