What is Chlorotoluron?

The Uses of Chlorotoluron

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).
