| Abstract | ||
| Four fungi , isolated from the rizosphere of Viccia faba in the fields of AI-Qadisiya district , were selected for their variable resistance to toxic insecticide Vapona ( Nogos ) at the range of 0.1, 0.3 , 0.5 ppm concentration and the 0.5 ppm concentration represtented to 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 percent of T . harzianum reached ( 28.8% ).with Vapona (Nogos ) on solid media in 0.5ppm concentration , but the inhibition percent reached(10.0%) in 0.1, 0.3ppm concentration. The inhibition percent of F. solani reached(45.5%) in0.5ppm concentration and(36.6%),(46.6% ) in 0.1 , 0.3ppm concentration. The results showed that A .niger ,R.stolinifer, T. harzianum were able to convert Vapona(Nogos) to other compounds in laboratory, but F. solani did not convert this insecticide . | ||
