Description

Cumyluron CAS NO 99485-76-4 is a selective herbicide belonging to the phenylurea chemical class, valued for its effective pre- and post-emergence control of a broad spectrum of annual grasses and broadleaf weeds. Its primary commercial value lies in providing reliable crop protection, enhancing yield potential for growers. This product is essential for agricultural professionals and formulators in the agrochemical industry seeking robust weed management solutions for various cropping systems.

Application

• Selective Herbicide in Agriculture: Used for pre- and post-emergence control of weeds in key crops such as rice, wheat, and soybeans.
• Broad-Spectrum Weed Management: Effective against problematic annual grasses (e.g., barnyard grass) and broadleaf weeds.
• Agrochemical Formulations: Serves as a key active ingredient in the manufacturing of emulsifiable concentrates (EC), wettable powders (WP), and suspension concentrates (SC).
• Integrated Pest Management (IPM): A component in rotational herbicide programs to manage weed resistance.
• Non-Crop Area Maintenance: Can be utilized for vegetation control in industrial sites and right-of-ways.
