Description

Propyrisulfuron is a selective, systemic sulfonylurea herbicide known for its high efficacy and low application rates. This compound is valued for its excellent post-emergence control of a broad spectrum of broadleaf and grassy weeds in key cereal crops. It is primarily targeted for use by agricultural chemical formulators and producers serving the global agrochemical industry. Its reliable performance makes it a critical component in modern integrated weed management programs.

Application

• Cereal Crop Protection: Post-emergence weed control in wheat, barley, and other small grains.
• Broadleaf Weed Management: Effective against resistant and hard-to-control broadleaf weeds in field crops.
• Grassy Weed Suppression: Control of annual and perennial grassy weeds competing with cereal yields.
• Agrochemical Formulation: Used as a key active ingredient (AI) in the manufacture of suspension concentrates (SC), wettable powders (WP), and water-dispersible granules (WG).
• Integrated Pest Management (IPM): A tool in rotation and mixture strategies to manage herbicide resistance.
• Non-Crop Area Weed Control: Can be utilized in industrial vegetation management programs.
