Sorghum is an important cereal produced as staple diet in Karnataka state of India and is prone to fungal infection during pre- and postharvest period. This paper reports the frequency and relative percentage of fungi associated with sorghum grain harvested in Karnataka State in 2004 and 2005. A total of 44 sorghum samples were analyzed for postharvest fungi by direct plating method on PDA and MGA 2.5agar medium. The genera Fusarium and Aspergillus were the mostfrequently isolated on sorghum grain. The other genera included Alternaria, Phoma, Curvularia, Penicillium andDrechslera. The data revealed a high frequency of Fusarium species(93.2%) and Aspergillus species (88.6%) with a relative percentage of23.3 and 19.6% among the 19 fungal genera recorded, respectively. The predominant fungal species recorded at high frequency were F.verticillioides (88.6%), A. flavus (72.7%), F. anthophilum (65.0%),A. niger (59.1%). These data indicate possible health hazards for humans and animals upon consumption of such contaminated food grain by toxigenic moulds.
