Finger millet (Eleusine coracana L.) is a member of eight minor millets group, constitutes about 81% of minor millets produced in India. The crop is affected by sheath blight caused by Rhizoctonia solani and leaf spot caused by Curvularia spp. Different doses of microalgae were applied @ (1.5, 2.5, 3.5, 4.5 and 5.5kg/acre) with irrigation at critical growth stages of crop (Vegetative phase, Flowering phase and Maturity phase) and observations were recorded on plant growth parameters and per cent disease incidence of R. solaniin leaf sheath. In-vitro effect of different botanicals (Trumphet leaf extract, Trumphet flower extract, Bryophyllum leaf extract, Ashok leaf extract and Moringa leaf extract) at different concentrations (5 and 10%) were screened on radial growth of Curvularia spp. which was isolated from the leaf of Finger millet. Results shows that, the application of microalgae of all the doses significantly reduced the per cent disease incidence of R. solani as compared with control at 60 and 90 DAT of microalgae. In-vitro effect of the botanicals on radial growth of Curvularia spp. was recorded after 96 hrs of incubation and the result showed that, among the treatments, Ashoka leaf extract at 5% and 10% significantly inhibited the percentage mycelial growth with 60.60% and 81.96% which was significant over other botanicals. All the botanical extracts significantly reduced the radial growth of Curvularia spp. from control.
