APPRAISE A SEED TREATMENT OF CARBENDAZIM 50% WP AGAINST SHEATH BLIGHT DISEASE OF RICE (ORYZA SATIVA L.)Ravindra, H., Narasimhamurthy H.B. and Balanagouda PatilAbstract An investigation was carried out to evaluate the efficacy of different dose of Carbendazim 50 % WP as seed treatment on the severity of sheath blight disease and yield contributing characters of rice in the Department of Plant Pathology and the field of University of Agricultural and Horticultural Sciences farm, Shivamogga, Karnataka during the period of 2017 to 2018. Four doses of Carbendazim 50 % WP were evaluated against sheath blight disease at three growth stages (flowering, milking and maturity) and yield attributing features. It was observed that disease severity was gradually increased from flowering stage to maturity stage with the age of the plant and minimum severity gave the maximum yield. seed treatment of Carbendazim 50% WP @ 4g / kg of seeds or Carbendazim 50% WP @ 3g / kg of seeds was found to be highly effective in managing sheath blight disease at early stage of crop growth and significantly reduces further spread under field condition by mitigating inoculum at seedling stage which in turn provided higher grain yield and other yield attributing characters. Present study clearly indicated that, Carbendazim 50 % WP was best chemical to control sheath blight disease as seed treatment. |
