Abstract
Abstract Herbicidal compositions consisting of an active herbicidal compound and an antidote therefor and the methods of use of the herbicide compositions are described herein. The antidote compound corresponds to the formula <IMAGE> wherein R1 can be selected from the group consisting of alkyl, haloalkyl, halogen, isocyanate, alkenylamino, halophenylamino, phenyl, substituted phenyl wherein said substituents can be selected from alkyl, alkoxy, halogen, nitro, amino and haloalkylaminosulfonyl; R2 and R3 can be the same or different and can be selected from hydrogen, alkyl, haloalkyl, alkoxy, alkenyl, alkynyl, alkynoxy, haloalkoxycarbonyl, alkynoxycarbonyl, carbamoyl, haloalkylthio, diacetonitrilocarbamyl, phenyl, substituted phenyl wherein said substituents can be selected from alkoxy, halogen, hydroxy, nitro and carbamoyl, and R2 and R3 taken together form the ring structure alkyloxazolidyl.
