Mode of Action

• Mode of Entry: Absorbed primarily through the root system (acropetal translocation) during pre-emergence application, and absorbed through green weed foliage with localized translaminar activity during early post-emergence application.
• Mode of Action: Photosystem II (PS II) Inhibitor (HRAC Group 5 / C1). It binds to the D1 protein of the photosystem II complex in chloroplast thylakoid membranes, blocking electron transport, halting photosynthesis, and generating lethal reactive oxygen species that cause rapid chlorosis, leaf desiccation, and complete weed mortality.

Dosage per Acre

• Per Litre of Water: 2.5 g – 4.0 g (approx. 40 g – 60 g per 15-litre spray pump)
• Per Acre (Pre-emergence in Maize & Sugarcane): 400 g – 800 g in 150–200 litres of water (apply onto moist, well-prepared soil within 0–3 days after sowing/planting using a flat-fan or floodjet nozzle).

Key Features & Benefits

• Comprehensive Dual Weed Protection: Clears both stubborn broadleaf weeds and annual grasses simultaneously, establishing a reliable chemical barrier on the soil surface.
• High Crop Selectivity & Residual Shield: Metabolized and safely detoxified by maize and sugarcane plants, preventing early weed competition and supporting vigorous early crop tillering and root development.
