Table 2: Growth-suppressing effects of diffusible and volatile metabolites from tomato-associated rhizobacteria toward Sclerotinia sclerotiorum noted after 5 days of incubation at 25°C. 1For each parameter, values followed by the same letter are not significantly different according to Duncan’s Multiple Range test (at P ≤ 0.05). 2Percentage of growth inhibition calculated using Rostami et al. [30] formula.
