<p>SYNERGISTIC HERBICIDAL COMPOSITIONS Synergistic herbicidal activity is displayed by a composition comprising the following two components: (a) an herbicidally effective amount of a thiolcarbamate of the formula < IMG > in which X is hydrogen, chlorine or bromine; and R1 and R2 are independently selected from the group consisting of C1-C6 alkyl and C5-C7 cycloalkyl, and (b) an herbicidally effective amount of a pyrrolidore compound of the formula < IMG > in which X' is hydrogen, chlorine or methyl; Y is hydrogen, chlorine, or bromine; Z is chlorine or bromine; R3 is hydrogen, alkyl, acetyl, chlorine, bromine, fluorine, iodine, trifluoromethyl, nitro, cyano, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, trifluoromethylthio, trifluoromethylsulfinyl, trifluoromethylsulfonyl, pentafluoropropionamido, or 3-methylureido; R4 is hydrogen, alkyl, chlorine, or trifluoromethyl; and, R5 is alkyl or hydrogen; at a weight ratio of (a) to (b) of from about 0.01:1 to about 20:1.</p> |
