Fig 5. Ba01 reduced the disease severity of potato common scab in pot assays.

The growth conditions of S. scabies PS07, Ba01, and potato plants were described in the materials and methods. A. Three five-week-old potato plants were used for each treatment: (a) mock control without inoculation of S. scabies PS07 or Ba01; (b) inoculation of S. scabies PS07 only; (c) inoculation of Ba01 only; (d) inoculation of PS07 and Ba01 on the same day; and (e) inoculation of PS07 first, and then Ba01 inoculation after 14 days. The bar represents 1 cm. B. The disease severity and disease incidence of the potato common scab were reduced when potato plants were inoculated with PS07 and Ba01 on the same day. Data were expressed as the average of tubers collected from three potato plants ± standard error of the mean. P values were calculated using Tukey's test. Asterisks (**) indicate P < 0.01 as compared to the treatment of PS07 only.
