Abstract

Herbicidal pyridine compounds of the formula <IMAGE> wherein Z and Y each represent a fluorine, chlorine, bromine, iodine, or hydrogen atom, or a trifluoromethyl, difluoromethyl, or chlorodifluoromethyl radical, provided that at least one of Z and Y is a halogenomethyl radical; R<1> represents hydrogen or an alkyl radical of 1 to 4 carbon atoms; and R<2> is a cyano group; a carboxyl group; one of a specified range of carboxamide or alkoxycarbonyl groups; a cyclohexyloxycarbonyl radical optionally substituted by one or more halogen atoms or methyl radicals; an alkenyloxy-carbonyl radical in which the alkenyl groups contains from 3 to 6 carbon atoms; a phenoxycarbonyl radical optionally bearing one or more halogen or methyl substituents; or a benzyloxycarbonyl radical, the phenyl group of which optionally bears one or more halogen or methyl substituents; and, in the case of compounds wherein R<2> is a carboxyl group, salts thereof are useful as selective herbicides for grass weeds in broad-leaved crops.
