Description

Sulfometuron is a selective, systemic sulfonylurea herbicide known for its high potency and long-lasting residual activity. It is valued for its effectiveness in controlling a broad spectrum of broadleaf weeds and grasses in non-crop and industrial areas. This compound is essential for vegetation management in sectors such as forestry, utility rights-of-way, and industrial site maintenance. Sulfometuron CAS NO 74223-56-6 is supplied to meet the stringent demands of professional applicators and formulators globally.

Application

• Forestry Management: Used for site preparation and conifer release to control competing vegetation.
• Industrial Vegetation Control: Management of weeds on non-crop areas like railway embankments, storage yards, and around factories.
• Utility Rights-of-Way: Essential for maintaining clear zones under power lines, around pipelines, and along communication corridors.
• Roadside and Highway Maintenance: Control of invasive and woody plant species along roadsides and medians.
• Aquatic Weed Control: Applied for managing specific vegetation in certain aquatic and wetland sites (subject to local regulatory approvals).
• Turf and Ornamental: Used in professional turf management for selective weed control in certain grass species.
• Agricultural Uses: Employed in specific cropping systems, such as sugarcane, for pre- and post-emergent weed control.
• Formulation Ingredient: Serves as a key active ingredient in the manufacture of various herbicide formulations.
