A Survey for assessment of postharvest disease prevalence on banana was carried out during 2015-16 in Dharwad and Hubballi markets. pathogenic studies of postharvest diseases of banana were carried out in the Department of Plant Pathology, College of Agriculture, University of Agricultural Sciences, Dharwad, Karnataka. Predominant diseases identified on banana fruits in Dharwad and Hubballi markets were anthracnose (Colletotrichum musae) and crown rot (Fusarium semitectum), Finger rot (Lasiodiplodia theobromae) and cigar end rot (Verticillium theobromae) were observed in traces. Seasonal variation in disease incidence and disease severity were observed, the mean disease incidence of banana anthracnose was maximum during rainy season (17.53 % in Dharwad & 10.30 % in Hubballi) in all the varieties when compared to winter (7.16 % in Dharwad & 6.56 % in Hubballi) and very low incidence was observed during summer (2.25 % in Dharwad & 2.22 % in Hubballi). Disease severity (per cent disease index) of anthracnose was recorded maximum in rainy season which was more in Dharwad (20.56 %). It is evident that disease incidence was more in rainy season in both the varieties when compared to winter season.
