Abstract
Abstract This invention relates to novel substituted imidazoles of the formula: ##STR1## wherein R 1 is a trifluoromethyl group, a halogen atom, an unsubstituted aryl group, a substituted aryl group, a heteroaromatic group, or a substituted heteroaromatic group; R 2 and R 3 are selected from a hydrogen atom, a halogen atom and a trifluoromethyl group, provided R 2 and R 3 are not concurrently halogen; and M is a hydrogen atom, an alkali or alkaline earth metal atom, a substituted carbonyl group, or other hydrolytically labile group. These compounds and compositions containing them exhibit herbicidal activity. Fungicidal activity of compounds of the invention is also shown.
