Description

Flupyrsulfuron-Methyl Sodium is a selective, systemic sulfonylurea herbicide. This compound is valued for its high efficacy at low application rates and its favorable environmental profile. It is primarily used by agricultural chemical formulators and producers for the control of a broad spectrum of weeds in cereal crops, ensuring crop safety and yield protection.

Application

• Pre- and post-emergence control of broadleaf weeds and some grasses in wheat and barley.
• Key component in selective herbicide formulations for cereal crop protection programs.
• Used for managing resistant weed biotypes in conjunction with other herbicide modes of action.
• Applied in agricultural settings for its systemic action, controlling both foliage and roots of target weeds.
• Integrated into professional turf management solutions for selective weed control in non-crop areas.
• Employed in manufacturing ready-to-use (RTU) liquid concentrates and water-dispersible granules (WDG).
