Abstract
Compositions comprise an urea herbicide and a N-(benzenesulfonyl) carbamate of the formula ##STR1## in which X and Y are independently selected from the group consisting of hydrogen and methyl; Z is selected from the group consisting of hydrogen, methyl, chloro, and trifluoromethyl; and R' is selected from the group consisting of 1-4 carbon alkyl, 1-4 carbon haloalkyl, 3-6 carbon alkenyl, 3-6 carbon haloalkenyl, 3-6 carbon alkynyl, cyanoethylthioethyl, 2-6 carbon alkoxyalkyl, diethylhydroxylamine, acetoxime, methylthioacetimidate, substituted phenyl, substituted benzyl, and sulfolane.
Claims30
A method of controlling undesirable vegetation and protecting soybeans from injury due to a urea herbicide which comprises applying to a locus where control is desired
- (a) an herbicidally effective amount of a urea herbicide of the formula ##STR14## in which R is chloro-substituted phenyl:
- R.sub.1 is selected from the group consisting of hydrogen and 1-4 carbon alkyl;
- and
- R.sub.2 is selected from the group consisting of 1-4 carbon alkyl and 1-4 carbon alkoxy;
- and
- (b) a non-phytotoxic but antidotally effective amont of a N-(benzenesulfonyl) carbamate of the formula ##STR15## in which X and Y are independently selected from the group consisting of hydrogen and methyl;
- Z is selected from the group consisting of hydrogen, methyl, chloro and trifluoromethyl;
- and
- R' is selected from the group consisting of 1-4 carbon alkyl, 1-4 carbon haloalkyl, 3-6 carbon alkenyl, 3-6 carbon haloalkenyl, 3-6 carbon alkynyl, cyanoethylthioethyl, 2-6 carbon alkoxyalkyl, diethylhydroxylamine, acetoxime, methylthioacetimidate, chloro-substituted phenyl, chloro-substituted benzyl, and sulfolane.
