الملخص EN

This study was carried out in the Microbiology laboratory at faculty of science, Misurata University, to isolate and identify the soil-borne fungi in the agricultural soils of three areas in Misurata city these including: Alsaket, Aldafnaya, Tomina.

the obtained results depending on the morphological characteristics of the fungal cultures and using the compound light microscope with assist of the modern scientific references showed that the soils contained many fungal genera, these are: fusarium, alternaria, aspergillus, rhizopus and penicillium using two different fungal culture media: Potatoes Dextrose Agar (PDA) and Czapek Dox Agar (CDA) and the serial dilution method at the concentrations of 10−2 and 10−3.

the isolated fungi were observed with various percentages which reached as high as 68.08% such as in genus of Penicillium sp.

in Alsaket area on PDA at 10−3, whereas the Alternaria alternata was the lowest observed genus with percentage of %5 in the same area (Alsaket) and culture media (PDA), but at the concentration of 10−2.

instead of 10−3.

Some fungal genera, to some extent were highly observed in some agricultural areas, while they were never observed in the same areas.

the culture media PDA and CDA also had a key role to isolate the soil-borne fungi giving different percentages of the fungal isolates at the two tested dilutions 10−2 and 10−3 in the three studied areas Alsaket, Aldafnaya and Tomina.
