Isolation of fungi associated with sorghum grains sampled from other localities, i.e. Assiut, Souhag and Qualiobiya Governorates yielded 370 isolates. The frequency varied according to the source. Alternaria alternata was the most dominant one, followed by Aspergillus flavus, Aspergillus niger and Fusarium moniliforme. The pathogenicity of these fungi as their effect on sorghum grain germination ability were tested. Aspergillus niger and Aspergillus flavus were most pathogenic to sorghum grains followed by Fusarium moniliforme and Alternaria alternata. Storage conditions studies of infested grains indicated that increasing grain moisture content as well as store temperature and storage period were usually accompanied by the increase in isolated fungi. Population of Aspergillus flavus and Aspergillus niger were greater after 3 months storage at any level of moisture content and temperature.
