| Chlorotoluron Usage And Synthesis |
| Uses | Herbicide. |
| Definition | ChEBI: A member of the class of ureas that is N-methyl urea substituted by a 3-chloro-4-methylphenyl group at position 3 and a methyl group at position 1. A herbicide that is non-toxic to honeybees but is moderately toxic to mammals, birds, ea thworms and most aquatic organisms. |
| Metabolism | Chlortoluron is rapidly metabolized in winter wheat. Hydroxylation of the methyl group on the phenyl ring has been demonstrated as a detoxification mechanism for chlortoluron resistance in winter wheat, whereas in the susceptible weed blackgrass (Alopecurus myosuroides Huds.), the main metabolite is the mono N-demethylated metabolite (107). In a tolerant weed, Persian speedwell (Veronica persica Poir.), chlortoluron is rapidly transformed to the nonphytotoxic di-N-demethylated metabolite (107). |
