Effect of F. oxysporum VCs on the amount/activity of antifungal metabolites secreted by T. harzianum. T. harzianum strain isolated from Custom GP was exposed to VCs from three F. oxysporum strains and un-inoculated PDA (Control) for 33 h. After removing the cellophane membrane along with T. harzianum culture, one plug of NRRL54003 culture was inoculated on each plate. Colony diameters after 3 days of incubation are shown. Values shown correspond to the mean ± SD of data from three replicates. Different letters indicate significant differences based on Fisher's test at P = 0.05.
