The invention relates to a new and improved method for the preparation of N-phosphonomethyl-glycine, a potent pre-emergence herbicide. According to the invention glycine, formaldehyde and a dialkyl phosphite are condensed in an aqueous alkaline medium to form a N-phosphonomethyl-glycine dialkyl ester, and the diester is hydrolyzed with a mineral acid.
