Tirazolopyramidine was effective in reducing density of Echinochloa colona, lschaemum rugosum, Cyperus iria, Fimbristylis miliacea and other weed spp. Its weed control efficacy was much less at 10 and 12.5 g ha⁻¹. Grain yield increased significantly with increase in doses of triazolopyramidine sulfonamide from 10 to 25 g ha⁻¹. None of the doses of triazolopyramidine had phystotoxic effect on transplated rice crop. Triazolopyramidine at 20 and 25 g ha⁻¹ applied 15 DAS produced grain yields similar to weed-free treatments.
