| Abstract | ||
| Four fungi , isolated from the rhizosphere of Viccia faba in the fields of AI-Qadisiya province , were tested for their variable resistance to toxic insecticide Nogos at the range of 0.1, 0.3 , 0.5 ppm concentration. The 0.5 ppm concentration represtents the initial concentration in the field soil. These fungi were Aspergillus niger, Rhizopus stolinifer (high tolerance ), Trichoderma harzianum ( moderate tolerance ) , Fusarium solani ( low tolerance ) . The inhibition percentage of T. harzianum reached 28.8% on solid media at 0.5ppm concentration, but the inhibition percentage reached 10.0% at 0.1, 0.3ppm concentration. The inhibition percentage of F. solani was 45.5% at 0.5ppm concentration and 36.6%, 46.6% at 0.1 , 0.3ppm concentration respectively . The results showed that A .niger , R. stolinifer, T. harzianum were able to convert Nogos to other compounds in laboratory, but F. solani have not the ability to convert this insecticide . | ||
