Initial symptoms of the mottle streak disease on finger millet were observed after only 45 days of sowing. Chlorotic mottling, streaking, striping and yellowing were the common symptoms on leaves and the diseased plants had more nodal branches and unproductive tillers. Among the weather parameters relative humidity and rainfall were positively and wind velocity was negatively correlated with disease incidence and the population of the vector Cicadulina bipunctella. A significant positive correlation existed between the vector population and disease incidence. In the disease management study seed extract of Harpullia cupanioides at 10% was found to reduce the mottle streak incidence by 61.42% with maximum yield of 2.28 t/ha. Acephate 0.01% and neem oil 1% spray were also found to be effective by reducing the disease incidence up to 39.6 and 36.4% with 2.23 and 2.18 t/ha of grain yield respectively. Enhanced activation of defense-related enzymes such as peroxidase (PO), polyphenol oxidase (PPO) and phenylalanine ammonia lyase (PAL) were noticed in AVP sprayed plants compared to control.
