Four fungi were isolated from the rhizosphere of Viccia faba located in the fields of Thi- Qar governorate for estimated their variable resistance to toxic Lead acetate at the different concentration( 50,100 , 250 , 500 ) ppm . These fungi were
Aspergillus niger , Rhizopus stolinifer , Trichoderma harzianum and Fusarium solani .
The results were showed that the Lead acetate was inhibited the growth of these fungi with all concentrations of Lead acetate on solid media compared with control , but in the broth media the results revealed that Lead acetate act to decrease the dry weight of R.stolinifer T. harzianum and F.solani at all concentrations except R. stolinifer which increase in 250 ppm as compared with control . At the same time the results showed that the dry weight of A. niger was increased with all concentrations of Lead acetate addition .
