Metoxuron
A member of the class of 3-(3,4-substituted-phenyl)-1,1-dimethylureas that is urea in which one of the nitrogens is substituted by a 3-chloro-4-methoxyphenyl group while the other is substituted by two methyl groups. It is a plant growth regulator and a pre- and post-emergence herbicide used for the control of grasses and broad-leaved weeds in carrots and cereals (e.g. wheat, barley and rye). — ChEBI
