Fusarium solani listed inmost notorious among the top ten plant pathogen. It is a soil-borne plant pathogen, caused root rot of the papaya which is responsible for estimate losses upto 40-95 percent. In this study we had collected different isolates of Fusarium solani from different districts of Bihar and the five isolates of Fusarium solani were selected on the basis of cultural, morphological and disease potential studies then further evaluated the fungus against native and commercial Trichoderma viride and Trichoderma harzianum by dual culture technique in the laboratory of the Department of Plant Pathology, DRPCAU Pusa, Samastipur in 2016. Observations were taken at 120 hours and 240 hours for the assessment of their inhibitory effects. In the presence of native T. viride and T. harzianum the variability in the growth inhibition over control is observed among five isolates, however the maximum growth inhibition was observedin the isolates FS-V(78.1%, 72.5%) and minimum in FS-II (73.1%, 68.1%) respectively, likewise in the presence of commercial T. viride and T. harzianum spp. maximum growth inhibition observed in FS-V (60.9%, 53.2%) and minimum in FS-II(53.8%, 49.2%) respectively were significantly reduced in comparison to control. Both the native and commercial Trichoderma spp. significantly reduced the mycelial growth of Fusarium solani isolatesin comparison to control.
