<p>This invention provides a method of reducing injury to sorghum or rice crop plants due to the application thereto of acetamide herbicides. The method is carried out by applying to the plant locus a safening effective amount of a compound having the formula wherein n is zero or one; X is selected from the group consisting of chloro, bromo, iodo, fluoro, lower alkoxy, phenoxy and phenoxy substituted by one or two groups independently selected from the group consisting of lower alkyl and halogen; R is alkyl having up to nine carbon atoms; when n is one, R' is selected from the group consisting of hydrogen, agriculturally acceptable cations, alkyl, lower alkenyl, lower alkynyl, alkoxyalkyl, haloalkyl, benzyl, phenyl and phenyl substituted by one or two members selected from the group consisting of halogen, lower alkyl, trifluoromethyl and nitro; when n is zero, R' is selected from the group consisting of chloro, amino and mono- or dialkylamino.</p> |
