The development of need based cost effective plant protection measures for effective management of rice diseases is the need of the future for higher and sustainable rice yield. Since, the existing chemical control measures being costly and may favour development of resistance in pathogens, the potential alternative methods have been explored in the present studies. An experiment was conducted to evaluate the effect of plant extracts and panchgavya in vitro against Rhizotonia solani causing sheath blight of paddy. Among the plant extracts, Maximum mycelial growth reduction was recorded in Garlic extract (80.51%) followed by Neem extract (59.77%), Dhatura extract (40.22) and Panchgavya (18.59) in cold water. Maximum reduction in mycelial growth was recorded in Garlic extract (75.18%) followed by Datura (45.92%) and Neem (41.70%) over control in hot water. Mycelial growth reduction was recorded maximum in Datura extract (63.99%) followed by Garlic extract (58.74%) and Neem extract (47.92%) in Acetone chemical. The plant extracts and pachgavya found effective in vitro against R. solani causing sheath blight of paddy during kharif season 2016-2017. Plant leaf extracts and Panchgavya taken in the study showed significant reduction in mycelial growth over control. Among all the treatments Garlic extract, Neem extract and Dhatura extract were found effective against Rhizoctonia solani in vitro whereas, Lemmon grass extract and Panchgavya were found less effective as comparision to Garlic extract, Neem extract and Dhatura extract.
