The suspension concentrate formulation ensures uniform spreading on water surface and better uptake by weeds. It provides effective weed management during the early crop growth stage and helps in reducing competition for nutrients and sunlight, leading to better crop establishment. Mode of Action Penoxsulam act by inhibiting acetolactate synthase enzymes in susceptible weeds. This block stops synthesis of essential branched chain amino acids leading to inhibition of cell division and plant growth. Treated weeds gradually show yellowing, stunted growth and finally die while crops remain safe at recommended dose. Benefits Control both grassy and broadleaf weeds effectively in paddy Post-emergence activity reduce manual weeding and labor cost Provide selective action safe for crop at recommended dose Uniform coverage ensure effective weed kill Help in better crop establishment and improved yield
