The Uses of Isoproturon

Isoproturon may be used as a reference standard for the determination of isoproturon in crops using high performance liquid chromatography (HPLC) with fluorescence detection combined with UV decomposition and post-column derivatization.

The Uses of Isoproturon

Pre-and post-emergence herbicide for control of annual grasses and broad-leaved weeds. Herbicide.

Definition

ChEBI: A member of the class of ureas that is 1,1-dimethylurea substituted by a p-cumenyl group at position 3. A selective, systemic herbicide used to control annual grasses and broadleaf weeds in cereals, its use within the EU has been banned after eptember 2017 on the grounds of potential groundwater contamination and risks to aquatic life; there have also been concerns about its endocrine-disrupting properties.

General Description

Isoproturon is a phenylurea herbicide used to control ryegrass, silky bentgrass, and broadleaf species in spring and winter wheat.

Hazard

Moderately toxic by ingestion, inhalation, and skin contact.

Metabolic pathway

The major degradation product of isoproturon in most soil samples is identified as 2-hydroxyisoproturon, and the polar metabolites characterized are monodesmethylisoproturon and 2- hydroxymonodesmethylisoproturon. The detection of isoproturon in soil solution down to 170 cm depth and in creek water in concentrations exceeding 4 μg l^-1 and also of the polar metabolites in concentrations up to 0.9 μg l^-1 indicates the mobility of this phenylurea herbicide and its degradation products.
