Thiencarbazone-methyl

Thiencarbazone-methyl (CAS 317815-83-1 ) is a selective herbicide active ingredient belonging to the triketone and sulfonylaminocarbonyl-triazolinone chemical classes.

It is registered under the ISO common name and marketed under trade names including Velocity and Capreno. It controls a broad spectrum of grass and broadleaf weeds in cereal crops.

The compound works by inhibiting acetolactate synthase (ALS), disrupting amino acid biosynthesis in target plants. It is primarily used in winter and spring wheat, barley, and corn production.

This active ingredient provides post-emergence control of economically damaging weeds such as blackgrass, ryegrass, and volunteer cereals. In corn herbicide formulations, it is often combined with isoxaflutole.

Formulators and registrants source the technical active ingredient for development of suspension concentrate (SC) and water-dispersible granule (WG) herbicide products for global distribution.

Its ALS-inhibitor mode of action makes it relevant for resistance management programs where rotation of herbicide classes is required by modern agronomic protocols and safety standards.

Thiencarbazone-methyl is supplied as a technical-grade active ingredient, typically as a solid powder or crystalline material meeting agreed specification sheets for industrial formulation use.

Standard supply documentation includes technical specification certificates aligned with FAO/WHO guidelines for pesticide active ingredients to ensure consistent quality and regulatory compliance.
