Synergistic herbicidal activity is displayed by a composition comprising the following two components: (a) an herbicidally effective amount of a thiolcarbamate of the formula <CHEM> in which X is hydrogen, chlorine or bromine; and R<1> and R<2> are independently selected from the group consisting of C1-C6 alkyl and C5-C7 cycloalkyl, and (b) an herbicidally effective amount of a pyrrolidone compound of the formula <CHEM> in which X min is hydrogen, chlorine or methyl; Y is hydrogen, chlorine, or bromine; Z is chlorine or bromine; R<3> is hydrogen, alkyl, acetyl, chlorine, bromine, fluorine, iodine, trifluoromethyl, nitro, cyano, alkoxy, alkylthio, alkylsulfinyl, alkysulfonyl, trifluoromethylthio, trifluoromethylsulfinyl, trifluoromethylsulfonyl, pentafluoropropionamido, or 3-methylureido; R<4> is hydrogen, alkyl, chlorine, or trifluoromethyl; and, R<5> is alkyl or hydrogen; at a weight ratio of (a) to (b) of from about 0.01:1 to about 20:1. |
