Abstract: Synergistic herbicidal activity is demonstrated by composition comprising aa mixture of (a) a trialkylsulfonium salt of N-phosphono-methylglycine having the formula (a) a herbicidally effective amount of a trialkylsulfonium salt of N-phosphonomethylglycine having the formula
in which R is C 1 -C 3 alkyl and n is 0 or 1, and (b) an herbicidally effective amount of a pyrrolidone compound of the formula X'O
in which X' is hydrogen, chlorine or methyl; Y is hydrogen, chlorine, or bromine; Z is chlorine or bromine; R' is hydrogen, alkyl, acetyl, chlorine, bromine, fluorine, iodine, trifluoromethyl, nitro, cyano, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, trifluoromethylthio, trifluoromethylsulfinyl, trifluoromethylsulfonyl, pentafluoropropionamido or 3-methylureido; R 2 is hydrogen, alkyl, chlorine or trifluoromethyl; and R 3 is alkyl or hydrogen; in a pyrrolidone:N-phosphono- methylglycine weight ratio of from about 1:6 to about 4:1:
