Management Strategies using Phytoextracts and Fungicides Against Cercospora Leaf Spot of Mungbean Incited by Cercospora canescens under in vitro and in vivo Conditions

Background: Cercospora leaf spot of mungbean [Vigna radiata (L.)] caused by canescens. It has become a severe menace to the growers Rajasthan in India and general causes economic losses under changing climatic scenario. Depending upon temperature humidity, it spreads rapidly susceptible varieties causing premature defoliation reduction size pods grains. In this study management was taken through botanicals fungicides is also an important segment present era, view hazards toxic chemicals or being developed resistance pathogens effective means for disease control. Methods: field-laboratory investigation during kharif 2018 2019 at Agronomy Farm, Sri Karan Narendra Agriculture University, Jobner, Jaipur, Rajasthan. The experiment conducted seven plant extracts 5, 10 15 per cent concentrations were evaluated vitro poisoned food technique. field experiments, further these applied as different viz., 0.1, 0.2 0.3% (at 10% conc.) assessed two foliar applications control disease. Result: Experiment carried out laboratory condition. Plant extracts, 100 inhibition mycelial growth obtained with garlic extract concentration. conditions, Hexaconazole (0.1%) proved most reducing intensity (55.58%) increasing crop yield (56.50%) followed + Captan. (10%) superior (52.85%) (33.96%) neem extract.
