3.4.3. Effect of T. atroviridae treatment on bean seeds germination in
the presence of F. solani
The results obtained showed that untreated control bean seeds
germinated at 80%. In the presence of F. solani alone, the germination rate dropped to 57%, indicating an inhibitory effect of 23% of
this pathogen on seeds germination. However, when bean seeds
treated with the pathogen at 4 105 conidia/mL were incubated
with the BCA (T. atroviridae) at varying conidia concentrations,
the promotion of germination appeared to be concentrationdependent with limited effect at 105 conidia/mL. The maximal
effect was however observed at 8 105 BCA conidia/mL with
77.09% germination (Fig. 8). Overall, it was noticeable that thepresence of BCA significantly reduced the deleterious effect of F.
solani on bean seed germination
