Suppression of B. velezensis strain P2-1 cell suspension on apple ring rot caused by B. dothidea. (A) Strain P2-1 cell suspension antagonized apple ring rot. Treatment with sterile distilled water or carbendazim was used as the negative and positive control, respectively. Bar = 1 cm. (B) Statistical analysis of the disease incidence. (C) Statistical analysis of disease lesion diameter. Each data represents the mean ± SD of three replicates. Disease lesion length and disease incidence were measured at 3 and 5 days post inoculation (dpi), respectively. Letters above the bars indicate statistical significance and different letters indicate significant different means (p < 0.01) based on Student’s t-test.
