This disclosure relates to alkyl N-trifluoroacetyl-N-phosphonomethylglycine amide and hydrazide derivatives, to herbicidal compositions containing same and to the herbicidal use thereof. These amide and hydrazide derivatives are useful as pre-emergent and/or post-emergent herbicides.
The novel N-trifluoroacetyl-N-phosphonomethyl- glycinate amide and hydrazide derivatives of this invention are those havina the formula
wherein R is an alkyl group of from 1 to 10 carbon atoms, a chloro lower alkyl group, a lower alkoxy lower alkyl group containing from 3 to 6 carbon atoms or a lower alkoxy lower alkoxy lower alkyl group containing from 5 to 9 carbon atoms, R' is hydrogen, lower alkyl, lower alkenyl or lower alkynyl, Z is a member of the class consisting of alkyl of from 1 to 6 carbon atoms, alkenyl of from 2 to 6 carbon atoms, alkynyl of from 3 to 6 carbon atoms, cycloalkyl containing from 3 to 7 carbon atoms or a R2 N - R3 group wherein R2 is lower alkyl, phenyl or substituted phenyl and R3 is hydrogen or lower alkyl and together with the nitrogen atom R2 and R3 can form a heterocyclic ring.
