Abstract: Fruit yield of mango can be drastically reduced or even lost due to infection of powdery mildew caused by Oidium mangiferae. It is widespread disease at the flowering stage of crop and even newly developed fruits drop down. Considering the endemic nature of disease under Konkan conditions the present investigation was carried out. In present study total six bio organics were tested against Oidium mangiferae in in vitro and in field conditions. All the tested bio organics significantly reduced the disease severity as compared to control. Among the six bio organics tested under invitro and in field conditions Neem oil at 10% concentration showed significantly superior over rest of treatments with higher inhibition in conidial germination to the tune of 62.54 per cent in In vitro condition and reduced the disease severity (27.00%) as compared to control (60.33%) in field condition.
