Description

Mesotrione is a selective, systemic herbicide belonging to the triketone chemical class, which functions as a potent inhibitor of the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD). This compound is valued for its excellent pre- and post-emergence control of broadleaf and some grass weeds in key agricultural crops. It is a critical tool for growers and formulators in the global agrochemical industry seeking effective, selective weed management solutions. Mesotrione CAS NO 104206-82-8 is a cornerstone active ingredient for modern, sustainable crop protection programs.

Application

• Selective Herbicide in Corn (Maize) Cultivation: Primary use for pre- and post-emergence control of a wide spectrum of broadleaf weeds (e.g., velvetleaf, lambsquarters, pigweed) and certain grasses in field corn, sweet corn, and popcorn.
• Turf and Ornamental Management: Used in professional turfgrass settings, including golf courses and sod farms, for control of challenging weeds like dandelion, clover, and ground ivy.
• Seed Production Crops: Applied in seed production fields of various crops to ensure clean, high-quality seed harvests by managing competing vegetation.
• Agrochemical Formulation: Serves as the active ingredient in the manufacture of suspension concentrates (SC), wettable granules (WG), and other commercial herbicide formulations.
• Industrial Vegetation Control: Employed in non-crop areas such as railways, utilities right-of-way, and industrial sites for total vegetation management.
• Research & Development: Used as a reference standard and biochemical tool in agricultural R&D for studying HPPD inhibition and developing new weed control technologies.
