Abstract: Field trial on organic management of complex disease of betelvine, caused by fungus, Colletotrichum capsici and bacterium, Xanthomonas axonopodis Pv. betlicola was carried out at experimental farm, AAU, Jorhat, Assam. Seven treatment combinations were tried viz., T1:Spraying with Org-Trichojal @5 ml/litre, T2: Spraying with bio-agent, Bacillus subtilis @ 5 ml/litre, T3: T1 + T2, T4: Spraying with Bordeaux mixture @5000 ppm,T5: Spraying with Streptomycin sulphate@ 400ppm, T6: Spraying with Bordeaux mixture @5000 ppm + Streptomycin sulphate@ 400ppm, T7: Absolute control. Observation on plant disease incidence and growth parameters were recorded. Result showed that lowest disease incidence (17.50%) of complex disease of betelvine, caused by fungus, C. Capsici and bacterium, X. axonopodis Pv. betlicola was observed when spraying with Bordeaux mixture @ 5000 ppm + Streptomycin sulphate @ 400ppm was done with 74.49% of reduction of the disease over control. Spraying with Bordeaux mixture @ 5000 ppm causes disease reduction upto 72.81%. This was followed by spraying with Streptomycin sulphate @ 400ppm with disease reduction of 69.90%. But plant growth parameters like plant height and leaf size and no. of leaves per plants were recorded highest in T3 where spraying was done with Org-Trichojal@5 ml/litre and B. subtilis @ 5 ml/litre.
