Figure 1: Differences /n 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.

Values in parentheses are square root transformed (x + 0.5)? values. Means within column followed by the same letter(s) are not significantly different from each other at 5% level of significance. Discussion In the present study, all antagonists significantly enhanced the height and biomass of bean seedlings as compared to bean seedlings inoculated with F. solani alone (Table 4 and Figure 2). The maximum plant height was observed in plants treated with isolates TS036 (38.5 cm), TSO19 (38.4 cm) and TS007 (37.9 cm) followed by isolates TS010 (36.8 cm), TS050 (36.7 cm), TS058 (36.6 cm) and TS022 (34.5 cm), while the shortest (33.4 cm) plant height was observed in plants treated with isolate TS025. Trichoderma treated seedlings increased in fresh biomass ranging from 24.1 to 40.5% over the control. Among the potential biological control agents in this study, isolates TS019, TS036, and TSO10 resulted in 40.5, 37.8 and 37.4%, respectively, increased
