Table 4: Mycelial growth inhibition of Fusarium oxysporum f. sp. lycopersici by diffusible and/or volatile metabolites produced by endophytic Bacillus spp. isolates, as compared to the controls, noted after 4 and 7 days of incubation at 25°C, respectively. For each column, values followed by the same letter are not significantly different according to Student Newman Keuls test at P ≤ 0.05. Numbers in parenthesis indicate the percentage (in %) of the mycelial growth inhibition of Fusarium oxysporum f. sp. lycopersici as compared to the untreated control.
