Description

Penoxsulam is a selective, systemic herbicide belonging to the sulfonamide chemical class, widely recognized for its post-emergence activity. Its primary value lies in providing effective, long-lasting control of a broad spectrum of grass and broadleaf weeds in key agricultural systems. This compound is essential for formulators and agricultural chemical producers serving the rice, turf, and aquatic vegetation management sectors globally. The product is supplied as a high-purity technical material, ensuring reliable performance in end-use formulations.

Application

• Rice Herbicide: A cornerstone application for selective post-emergence control of grasses, sedges, and broadleaf weeds in paddy rice fields.
• Turf Management: Used in professional turf and ornamental grass management for weed control in golf courses, sports fields, and lawns.
• Aquatic Weed Control: Effective in managing invasive and nuisance vegetation in irrigation canals, ponds, and other slow-moving water bodies.
• Industrial Vegetation Management: Applied in non-crop areas such as roadsides, utility rights-of-way, and industrial sites.
• Formulation Intermediate: Serves as a key active ingredient for the manufacture of emulsifiable concentrates (EC), suspension concentrates (SC), and water-dispersible granules (WG).
• Integrated Weed Management (IWM): A valuable tool in resistance management programs, often used in rotation or mixture with other herbicide modes of action.
