Mycoflora population from soil of organic and conventional fields was investigated at different plots. The fungi were isolated by using soil dilution method. Total of six genera were obtained from 10 soil samples. On the basis of cultural and microscopic characteristics, the isolated strains were identified as Aspergillus sp. Penicillium sp., Alternaria sp., Fusarium sp., Cladosporium sp. and Gliocladium sp. Aspergillus species showed the highest percentage among the six genera. This work aims to search different potential bio-agents fungi from soil's microflora sampled from selective organic plots. In vitro, direct confrontation between pathogens and antagonists showed that Gliocladium roseum, Aspergillus pseudoelegans, A. niger, A. terreus, A. nidulans and A. fumigatus inhibited the mycelial growth of Fusarium solani and Alternaria alternata, with varying efficiencies. The obtained inhibition rates reach up above 44%. The mycoflora analysis proved that these soils are rich in fungi that could play a crucial role in the biological treatment as antagonists of pathogen fungus.
