ABSTRACT:
N-(substituted benzenesulfonyl) carbamates as new compositions of matter useful as active herbicidal antidotes to protect against and decrease crop injury when used with a thiocarbamate herbicide when applied in various methods; improved herbicidal compositions and utility of said compositions to protect against and decrease phytotoxic crop injury when employing thiocarbamate herbicides and a two-part herbicide system comprising a first-part of one or more thiocarbamate herbicide and a second part of an effective antidote therefor compound said antidote compounds of the class N-benzene sulfonyl carbamates having the formula ##STR1## wherein X is hydrogen, bromo, chloro, methoxy, trifluoromethyl, and methyl; n is an integer from 1 to 3 inclusive, provided that when X is bromo, trifluoromethyl, or methoxy, n is 1; and R is selected from alkyl, haloalkyl wherein halo is chloro or fluoro, alkenyl, haloalkenyl and wherein halo is chloro, alkynyl, trifluoroacetamidomethyl, dialkylamino cyanoalkylthioalkyl, phosphonomethyl, lower alkyl substituted phenyl, 4-chlorophenylthiomethyl, alkoxyalkyl, alkylthioalkyl, cyanoalkyl, alkoxycarbonylalkyl, formamidoalkyl, alkoxycarbonylalkenyl, alkylcarbonylalkyl, 1,3-dioxacyclohexane-5,5-methylene, phenyl, chlorophenyl, benzyl, 4-chlorobenzyl, 4-methoxybenzyl, 3-pyridylmethyl, phenoxyethyl, 3-phenylpropyn-2-yl, methylthioacetimino, acetone imino and benzaldimino.
