N-organo-N-phosphonomethyl glycine-N-oxide(I; R, R1, R2 = H, C1-10 monovalent hydrocarbon group; R3 = compd. (III), C1-18 primary or secondary aliphatic hydrocarbon group (this group is able to substituted with halogen, amino. carboxyl, alkoxy, aryloxy, carboalkoxy, aryl or aminoalkylamino), useful as herbicides and vegetable growth controlling agent, was prepd. by oxidation of compd.(II) in the presence of acidic or aklaline solvent at 25-80≦̸C.
