Description

Metsulfuron Methyl CAS NO 74223-64-6 is a selective, systemic sulfonylurea herbicide. It is valued for its high efficacy at low application rates against a broad spectrum of broadleaf weeds and some annual grasses in various crops. This compound is a critical active ingredient for agricultural professionals and formulators seeking reliable, cost-effective weed control solutions. Its systemic action ensures thorough plant elimination, supporting sustainable crop management practices.

Application

Metsulfuron Methyl is a versatile herbicide used in multiple agricultural and non-crop settings. Its primary and related applications include:

• Cereal Crops: Selective post-emergence control of broadleaf weeds in wheat, barley, and oats.
• Pasture and Rangeland Management: Management of invasive brush and weed species to improve forage quality.
• Industrial Vegetation Control: Use on non-crop areas such as roadsides, railways, and utility rights-of-way.
• Forestry: Site preparation and conifer release programs to control competing vegetation.
• Turf Management: Selective weed control in certain managed turfgrass systems.
• Agricultural Formulations: Serves as a key technical material for manufacturing wettable powders (WP), water-dispersible granules (WG), and other herbicide formulations.
