Bacillus velezensis CB13 reduced the disease incidence and disease index of peanut stem rot in pot assays. (A) Pot assays for stem rot disease control; (B) disease index; (C) disease incidence; (D) control effect. CK: infected peanut plants without treatment; THI: infected peanut plants sprayed with 20 mL of 240 g/L thifluzamide (diluted 500×); RI: infected peanut plants watered with 20 mL of bacterial inoculum (diluted 10×); ST: seeds were soaked in bacterial inoculum (diluted 10×) for 24 h before sowing. Data are the means ± SE of three repeated experiments. Significant differences are shown using asterisks (*p < 0.05, **p < 0.01, and ***p < 0.001).
