Abstract
The incidence of Aspergillus species on grapes (Vitis vinifera) in West Azarbayjan province was studied.
Samples were collected in July 2011 from different vineyards.
Single conidial heads were used for isolation and purification.
According to morphological criteria A. niger aggregate, Aspergillis flavus, A. ochraceus, Eurotium repens, A. carbonarious and Penicillium sp. were identified in grape vineyard in West Azarbayjan province.
The result showed that black Aspergilli are the most prevalent in vineyards and the less susceptible to sodium hypochlorite than the other Aspergilli or maybe some of them cause internal infection in grape berries.
Overall, Aspergillus section Nigri was the most common species in grape in West Azarbayjan province.
The species such as A. ochraceus, A. niger, A. carbonarious, have been reported to be the main producers of ochratoxin A in foodstuff as well as A. niger which can produce fumonusin B2 and B4. In point of health risks, ochratoxin A and fumonisin B2 are currently the most problematic compounds in food and feed in addition to aflatoxins.
