The invention provides N-Phosphonomethylglycine derivatives of the general formula I
wherein R,, R2 and R3 are independently selected from-OH and -OR4 wherein R4 is a salt forming cation iminourea derivative of the general formula II
wherein R5, R5, R6, R6, and R7 are independently H, NH2,
or an aryl, cycloalkyl or straight or branched chain alkyl or alkenyl group optionally substituted by hydroxy or halogen, or an alkylaryl group, provided that at least one but no more than two of R,, R2 or R3 are OR4; no more than two R5, R5, R6, R6, are aryl or substituted aryl; and no more than one of R5, R5., R6, R6, and R, is CH2OH. The invention also provides a process for preparing the above N-Phosphonomethylglycine imino urea salts as well as providing phytotoxic compositions containing the same.
