Mode of Action

• Mode of Entry: Absorbed rapidly through weed foliage, stems, and root systems, translocating systemically through both xylem and phloem vessels directly to the active growing points (meristems).
• Mode of Action: Acetolactate Synthase / Acetohydroxyacid Synthase (ALS/AHAS) Inhibitor (HRAC Group 2 / Group B). It blocks the biosynthesis of essential branched-chain amino acids (valine, leucine, and isoleucine), causing immediate arrest of weed cell division and growth, followed by chlorosis, purpling of growing tips, necrosis, and complete plant mortality within 10 to 15 days.

Dosage per Acre

• Per Litre of Water: 2.0 ml – 2.5 ml (approx. 30 ml – 40 ml per 15-litre spray pump)

Key Features & Benefits

• Comprehensive 3-Way Paddy Weed Control: Controls grasses (especially barnyard grass), tough annual sedges, and broadleaf weeds simultaneously in a single early post-emergence application.
• Advanced Oil Dispersion (OD) Advantage & Crop Safety: Enhances spray retention, cuticle penetration, and rainfastness without requiring additional wetting agents, while rice plants rapidly metabolize and detoxify the active compound for zero crop injury.
