Figure 1: Differences In vitro antagonistic effect of selected Trichoderma isolates against Fusarium solani using dual culture method four (top) and five (bottom) days after inoculation. At the bottom of the plates overwhelming growth of Trichoderma isolate on F. solani, which indicates parasitic interaction. Heavy sporulation by Trichoderma is seen on and in vicinity of F. solani colony. Each perti dish has F. solani at the upper and Trichoderma at the lower side of the petri plate.
