Abstract
Abstract Compounds having the structural formula WHEREIN EACH X represents hydrogen, chlorine, or fluorine and each Y represents halogen, lower alkyl, lower alkoxy, cyano, trifluoromethyl, or nitro, and n represents an integer in the range of zero to four; are useful as preemergence and postemergence selective herbicides. Illustrative of these compounds are N,N''-bis(trichloroacetyl)-4,5-dichloro-o-phenylene diamine, N,N''-bis(chloroacetyl)-4,5-dichloro-o-phenylene diamine, and N,N''-bis(trifluoroacetyl)-3,4,5-tribromo-o-phenylene diamine.
