Abstract: The powdery mildew, Oidium mangiferae Berthet is a major disease of mango in Konkan region of Maharashtra. The epidemiological study was conducted at Regional Fruit Research Station, Vengurle, M. S. during 2013-14 and 2014-15. The ten Alphonso mango trees from unsprayed plot were selected and 15 panicles of each tree were tagged and observed seven days interval for disease incidence. During the year 2013-14 and 2014-15 first powdery mildew appearance was noticed in the 2nd fortnight of January and 1st fortnight of January respectively. However, maximum disease intensity was recorded in the 2nd fortnight of March (85.60% & 73.40% during 2013-14 and 2014-15, respectively). The incidence of powdery mildew was significant and positively correlated with minimum temperature. Whereas, there was positive and non-significant correlation with evening humidity, maximum temperature and rainfall.
