Experiments were conducted at Binuria under Bolpur-Sriniketan block of West Bengal (India) during 2012-13 to evaluate the efficacy of some fungicides including a few bio-enriched molecules for management of late blight and viral diseases of potato (Solanum tuberosum L.). Management of late blight using Rakhwala (liquid organic fungicide) proved well but it gave best result when applied along with Mancozeb. Among the other formulation of fungicides, Melody Duo (Iprovalicarb + Propineb) found effective in reducing the disease severity. Increased yield and improved tuber quality was also recorded in these treatments. Repeated application of Green Spot (a natural pathogen related protein synthesizer) considerably improved the plants health by keeping the viral infection (Severe mosaic and PLRV) at lower level that resulted in increase of tuber yield. This information may be helpful for sustainable production of disease free seed tubers as well as quality potato tubers.
