Study of bio-efficacy and Phytotoxicity of New Generation Herbicides on Triafamone and Ethoxysulfuron in Direct Seeded Rice (Oryza sativa)
Abstract
The herbicides triafamone + ethoxysulfuron at (200g/ml/ha and 225 g/ml/ha) and triafamone (225 g/ml/ha) applied at 15 days after planting recorded the zero weed counts of individual species viz., grasses, sedges and broad leaf weeds, weed dry matter production and weed control index favoring to higher grain yield of (5.2 and 5.34 t/ha). Triafamone + ethoxysulfuron (175 g/ml/ha) recorded the least weed count, weed dry matter and cent percent weed control index recorded at 42 days after application (DAA). Ethoxysulfuron (150g/ml/ha) was next in order. No phytotoxicity symptoms was observed in the treatments including double the recommended dose of triafamone + ethoxysulfuron (450 g/ml/ha and 225 g/ml/ha) in respect of leaf chlorosis, tip burning, necrosis, epinasty, hyponasty, vein clearing, wilting and rosetting.
