الملخص

Various fungal species (Eleven species) belonging to different five genera have been. ‘‘Malty and Blanka’’ found in or on localized broad bean seeds cultivar. These fungi were purified and identified as Aspergillus flavipes, Aspergillus niger, Aspergillus terreus, Aspergillus ustus, Aspergillus wentii, Penicillium brevicompactum, Penicillium expansum, Fusarium moniliforme, Rhizopus stolonifer and Mucor eircinellricles.

Results also indicated that Aspergillus flavus isolate No. (1) was significantly more pathogenic as it totally inhibited seed germination (0%) and caused the highest percentage of seed infection (100%), followed by Aspergillus niger isolate No.(1) and Aspergillus flavus isolate No. (3). It was found that Aspergillus flavus isolate No. (2) and No (5) were the least pathogenic. However, the difference between any two tested fungi was significant. In this study showed that Trichoderma album and Trichoderma harzianum significantly inhibited the growth of Penicillium expansum by 77.7 and 72.2%, respectively, followed by Aspergillus flavus and Aspergillus flavipes. However, Aspergillus ustus was the least affected fungus in this concern (22.2%).
