Abstract
This disclosure relates to N-phosphonomethylglycine derivatives wherein a benzoxycarbonyl group is attached to the nitrogen and alkoxy, alkenylthio, alkylthio, phenylalkylthio, phenylthio or substituted phenylthio groups are attached to the phosphorus atom and alkyl, chloroalkyl, alkoxyalkyl or alkoxyalkoxyalkyl groups are attached to the carboxyl group of the molecule. These compounds are useful as herbicides.
