Documented Uses

• Used as selective post-emergence herbicide for control of broad-leaved weeds in wheat, barley, oats, herbage seed crops, grassland, under fruit trees and vines, and sport and ornamental turf; [HSDB] Mecoprop is a 50:50 ratio mixture of the R and S isomers of 2-(4-chloro-2-methylphenoxy)propanoic acid; Mecoprop is being replaced in the US by Mecoprop-p, which is the R isomer and the active isomer; [Reference #1]
• Dioxins occur as by-products from the manufacture of organochlorides, the bleaching of paper, chlorination by waste and drinking water treatment plants, municipal solid waste and industrial incinerators, and natural sources such as volcanoes and forest fires. (L177, L178)
