Description

Metoxuron is 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). It has a role as an agrochemical, an environmental contaminant, a herbicide, a xenobiotic, a photosystem-II inhibitor and a plant growth regulator. It is a 3-(3,4-substituted-phenyl)-1,1-dimethylurea, a monomethoxybenzene and a member of monochlorobenzenes.
