Abstract: Sarpagandha (Rauvolfia serpentina) belongs to family Apocynaceae is an evergreen, perennialshrub, erect of the height upto 60cm. It’s root are tuberous with pale brown colour, leaves of the plant are in whorls of three lanceolate or obovate, bright green in colour, flowers are in irregular, corymbose infloresence with white and pink colour. Fruits are drupe, single or didymous shining black when fully riped. The minimum percent disease severity was recorded with Neem leaf extract (25.03) followed by botanicals spray, Tulsi leaf extract (27.15), Arjun bark extract (30.46) and Garlic bulb extract (34.66) while, maximum percent disease severity was recorded with Castor bean leaf extract (41.71) as compared to control (76.26). The minimum percent disease severity was recorded with Mancozeb @ 0.25% concentrations (21.77%).The maximum percent control was recorded with Neem leaf extarct (67.16%) followed by Tulsi leaf extract (64.81%), Arjun bark extract (59.94%) and Garlic bulb extract (53.20%) while, minimum percent disease control was recorded with botanical spray of Castor bean leaves extract (45.29%). Highest percent disease control was recorded in fungicide with Mancozeb @ 0.25 % (71.53%). The results showed that each plant extract were more or less inhibit disease growth of Cercospora rauvolfiae. The effectiveness of the extracts and the maximum disease management was recorded with Neem leaf extract
