Inhibition of B. cinerea and M. oryzae growth by ES2 and ES2-14. A, Representative cultures of M. oryzae grown on complete minimal medium supplemented with 0.1% DMSO or different concentrations of ES2 or ES2-14 for 4 d. B, Diameter of 4-d-old complete minimal medium cultures of M. oryzae in the presence of ES2 or ES2-14. Data represent means ± sd (n = 6). C, Four-day-old V8 cultures of B. cinerea colonies with 0.1% DMSO or different concentrations of ES2 or ES2-14. D, Diameter of 4-d-old V8 B. cinerea colonies in the presence of different concentrations of ES2 or ES2-14. Data represent means ± sd (n = 6). The diameters of the petri dishes are 6 cm for M. oryzae and 10 cm for B. cinerea. **P < 0.01 (B and D) as compared with the DMSO control, determined by paired t test.
