An aeromycological studies over onion store houses of Nashik district was conducted during two successive seasons from April to October, 2010 and 2011 by using Tilak’s air Sampler (Tilak & Kulkarni, 1970) and petri plate exposure method. In both the seasons of investigation, suspended fungal particles, dust, insect parts, pollens, spores, scales and hairs of rodents were recorded in enormous quantity. Many of the pathogenic airborne fungal spores are significantly related to the incidence of disease to the onion bulbs and also causing the allergic reactions such as hay fever, rhinitis, asthma, skin rashes sneezing etc\n to the workers of the store houses. The air borne fungal diseases of onion bulbs during storage conditions like Black mold (Aspergillus niger), neck rot of onion bulb (Botrytis alli) and onion basal rot (Fusarium oxysorium) were discussed in relation to the concentration of respective causal pathogen and the meteorological conditions like temperature, humidity and rainfall. The black mold disease is the serious problem occurred during the storage condition of onion which is totally related with the high humid environment and the improper onion storage.
