Antagonistic activity of Bacillus subtilis PTA-271 and Trichoderma atroviride SC1 against the Neofusicoccum parvum strain Bt67. (A) T. atroviride SC1 (Ta) was applied 48 h before N. parvum (Np) in the opposite sides of PDA plates. (B) B. subtilis PTA-271 (Bs) was applied 48 h before N. parvum (Np-Bt67) in the opposite sides of PDA plates. (C) B. subtilis PTA-271 (Bs) was applied 48 h before N. parvum (Np) and T. atroviride (Ta) at distinct areas of the PDA plates. (D) B. subtilis PTA-271 (Bs) and T. atroviride SC1 (Ta) were applied 48 h before N. parvum (Np) at distinct areas of the PDA plates. All plates were incubated at 28°C. Pictures of each plate condition were taken from day 1 to day 11 after the first inoculation. Photos on top are the control of Np-Bt67 and photos at the bottom indicate the confrontation assay at day 4 (left) and day 11 (right).
