In-Vitro Evaluation of Plant Leaf and Oil Cake Extracts Against Rhizoctonia Solani Causing Frenchbean Root Rot Disease
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 3
Abstract
In the present study, effects were made to explore the efficacy of various plant leaf and oil cake extracts against Rhizoctonia solani. Efficacy of eight leaf extracts viz., Neem (Azadirachta indica), Karanj (Pognamia pinnata), Bakain (Melia azadirachta), Datura (Datura stramonium), Bael (Aegle marmelos), Eucalyptus ( Eucalyptus obliqua), Sindwar (Vitex negunda), Marigold (Tagetes erecta) at 10 and 20 percent concentrations and nine oil cake extracts viz., Niger (Carthanus tinctrorius), Neem (Azadirachta indica), Soybean (Glycine max), Mustard (Brassica compestris), Linseed (Linum usitatissimum), Sesamum (Sesamum indicum), Karanj (Pongamia pinnata), Groundnut (Arachis hypogaea), Mahua (Madhuca indica) at 5 and 10 percent concentrations were evaluated by using poisoined food technique in-vitro condition and recorded the radial growth of the mycelium. The neem (A. indica) leaf extract recorded maximum mycelial growth inhibition by 66.87, 54.12 percent after 4 and 7 days incubation, respectively at 10 percent concentration and 98.17 and 74.58 percent after 4 and 7 days incubation, respectively at 20 percent concentrations. Maximum mycelial growth inhibition by 64.15, 66.48 percent after 4 and 7 days incubation, respectively at 5 percent concentration and by 81.84, and 64.97 percent after 4 and 7 days incubation, respectively at 10 percent concentration was recorded with neem oil cake extracts (A. indica). The present study revealed that neem leaf and oil cake extracts could be explored for the possible control of deadly pathogen R. solani.
