Antifungal activity in acetone extracts from the roots of tomato seedlings treated with bacterial cells of Paenibacillus strains 12HD2 and 42NP7 against FORL (A) and an indicator phytopathogenic fungus, Colletotrichum dematium (B). Antifungal activity was evaluated based on the relative diameter of mycelial growth from a small mycelial block of the fungus relative to growth following a treatment with a control solution (50% methanol). Each value indicates the mean of three experiments and bars denote the standard error of the mean. Different letters within each column indicate significant differences according to Fisher’s LSD test.
