Claims21
A method of reducing herbicidal injury to sorghum plants due to application thereto of acetanilide herbicides which comprises applying to the plant locus a non-phytotoxic safening effective amount of a compound having the formula ##STR9## where R is equal to halogen, hydroxy, lower alkoxy or benzyloxy R.sub.1 is lower alkyl, halo (lower) alkyl, phenyl, or phenyl substituted by one to three groups, which may be the same or different, selected from the group consisting of halogen, lower alkyl, trifluoromethyl and cyano.
A mixture which comprises a herbicidally effective amount of an acetanilide herbicide and a safening effective amount of a compound having the formula ##STR10## where R is equal to halogen, hydroxy, lower alkoxy, or benzyloxy;
- R.sub.1 is lower alkyl, halo (lower) alkyl, phenyl, or phenyl substituted by one to three groups, which may be the same or different, selected from the group consisting of halogen, lower alkyl, trifluoromethyl and cyano.
