ABSTRACT:
Herbicide combinations with improved residual activity comprising (a) compounds of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of lower alkyl having from 2 to 6 carbon atoms, haloalkyl, benzyl and substituted benzyl, phenethyl, pyridylmethyl, cycloalkyl having from 3 to 6 carbon atoms, and haloalkenyl having from 3 to 6 carbon atoms, and R.sub.2 and R.sub.3 are each independently selected from the group consisting of C.sub.2 -C.sub.6 alkyl, C.sub.2 -C.sub.6 alkenyl, and C.sub.3 -C.sub.8 cycloalkyl, provided further that R.sub.2 and R.sub.3 can join with the nitrogen to which they are attached to form a 5 to 6 carbon ring structure, and (b) an herbicidally effective amount of a chloroacetanilide having the formula ##STR2## in which R.sub.4 is a straight or branched chain lower alkyl group having from 1 to 6 carbon atoms; R.sub.5 is a straight or branched chain lower alkyl group having from 1 to 6 carbon atoms; and R.sub.6 is ##STR3## where R.sub.7 is a straight or branched chain lower alkyl group having from 1 to 6 carbon atoms.
