Description

Bispyribac-Sodium is a selective, systemic post-emergence herbicide belonging to the chemical class of pyrimidinyloxybenzoic acids. This compound is valued for its high efficacy and low application rates, making it a cost-effective solution for broad-spectrum weed control. It is primarily required by agricultural formulators and producers serving the rice cultivation industry, as well as research institutions developing novel crop protection solutions.

Application

• Selective Weed Control in Rice Paddies: Primary application for post-emergence control of a wide range of grassy and broadleaf weeds, including barnyardgrass, sedges, and broadleaf weeds.
• Agricultural Formulations: Used as the active ingredient in the manufacture of soluble concentrates (SL), suspension concentrates (SC), and water-dispersible granules (WG).
• Integrated Pest Management (IPM) Programs: A key component in resistance management strategies due to its unique mode of action (inhibition of acetolactate synthase, ALS).
• Turf and Ornamental Management: Employed in professional turf management for certain grass species and in non-crop areas.
• Research & Development: Serves as a reference standard and biochemical tool in agricultural research for studying ALS inhibition and plant physiology.
