Claims15
A compound of the formula ##STR7## 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 ##STR8## group wherein R.sup.2 is lower alkyl, phenyl or substituted phenyl with up to five substituents individually selected from the class consisting of halogen, lower alkyl and lower alkoxy and R.sup.3 is hydrogen or lower alkyl.
A herbicidal composition comprising an inert adjuvant and an effective amount of a compound of the formula ##STR10## 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 ##STR11## group wherein R.sup.2 is lower alkyl, phenyl or substituted phenyl with up to five substituents individually selected from the class consisting of halogen, lower alkyl and lower alkoxy and R.sup.3 is hydrogen or lower alkyl.
A herbicidal method which comprises contacting a plant or the plant growth medium with a herbicidally effective amount of a compound of the formula ##STR13## 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 ##STR14## group wherein R.sup.2 is lower alkyl, phenyl or substituted phenyl with up to five substituents individually selected from the class consisting of halogen, lower alkyl and lower alkoxy and R.sup.3 is hydrogen or lower alkyl.
