Efficacy of Different Fungicides and Bio-agent against Collar Rot of Chickpea

Disease control efficacy of six fungicides and bio-control agent viz., Trichoderma viride 8g/kg, Vitavax powder 2g/kg (Carboxin37.5% + Thiram 37.5%), Vitavax powder 1g/kg + Trichoderma viride @ 4g/kg, Carbendazim 0.75g/ha+ Thiram 1g/kg and soil application of Trichoderma viride @ 2.5kg/ha were evaluated against collar rot (Sclerotium rolfsii) of chickpea genotype L 550 during Rabi season 2009–10 and 2010–11. The disease mortality was significantly reduced by fungicidal sprays. The minimum per cent disease mortality was recorded in Carbendazim + Thiram (18.90) followed by Vitavax powder + Trichoderma viride (21.24%), Vitavax powder 2g/kg (Carboxin37.5% + Thiram37.5%) (25.10%), Soil application of Trichoderma viride (28.12%) and Trichoderma viride (30.72%) against control (37.18%). Pooled data for the year 2009–10 and 2010–11 revealed that two spray with Carbendazim 0.75g/ha+ Thiram 1g/kg at 10 days interval and also enhance grain yield of 2178 kg/ha followed by Vitavax powder 1g/kg + Trichoderma viride @ 4g/kg 2071 kg/ha as compared to check 1286 kg/ha.
