Synergistic herbicidal compositions

Abstract

Synergistic herbicidal activity is displayed by compositions comprising the following two components: (a) a pyrrolidone of the formula ##STR1## and (b) an acetanilide of the formula ##STR2## in which R.sup.1 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and chlorine; R.sup.2 is selected from the group consisting of hydrogen, C.sub.2 -C.sub.6 alkoxyalkyl, and C.sub.3 -C.sub.6 carbalkoxyalkyl; R.sup.3 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and chlorine; R.sup.4 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, and chlorine; and R.sup.5 is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, chlorine, and --NHSO.sub.2 CF.sub.3, at a weight ratio of (a) to (b) of from about 0.1:1 to about 50:1.
