Abstract
Abstract Crops are protected against injury from triazine herbicides by application of certain N-benzenesulfonyl carbamates as herbicide antidotes. The N-benzenesulfonyl carbamates have the general structural formula <IMAGE> wherein each of X1, X2, X3, X4, and X5 is independently selected from the group consisting of hydrogen, halogen and lower alkyl, with the proviso that when X3 is lower alkyl, X1 and X5 are not both hydrogen; and R is selected from the group consisting of lower alkyl, alkenyl, alkynyl and alkyl and alkenyl radicals substituted with up to five halo atoms.
