Target Weeds

PENOSUN is used against the following weeds in paddy fields:

• Echinochloa crus-galli – Barnyard Grass
• Echinochloa colona – Jungle Rice
• Cyperus difformis
• Cyperus iria

Mode of Action

Mode of Entry: Penoxsulam is absorbed through weed foliage, stems, and root systems. It moves systemically through the xylem and phloem to the active growing points (meristems).

Mode of Action: Penoxsulam is an 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.

This causes 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 and Application

• Per litre of water: 2.0 ml – 2.5 ml
• Per 15-litre spray pump: Approximately 30 ml – 40 ml
• Per acre: 400 ml – 450 ml
• Water volume per acre: 150–200 litres
• Application method: Foliar post-emergence spray
• Nozzle: Flat-fan or floodjet nozzle
