Plate confrontation and VOCs assay of P. polymyxa Sb3-1 and V. longisporum ELV43 in three different growth media (PDA, R2A, and WYA) for nine days. Dashed columns show growth of V. longisporum ELV43 in the presence of P. polymyxa Sb3-1 (A) or its VOCs (B), while the gray columns illustrate the growth of V. longisporum ELV43 without P. polymyxa Sb3-1 (A) or its VOCs (B). The assay was performed in nine replicates. The asterisk (*) denotes values that varied significantly from control group values (P < 0.05) defined using pairwise t-test or non-parametric Mann–Whitney U-test, depending on the distribution of the samples.
