Microbial effect on root knot nematode infection. a, b Effect of soil microbiome of healthy and diseased rhizosphere soil from eggplant and cucumber on RKN infection in tomato. c Screening of bacterial strains against RKN infection. d Effect of two bacterial biocontrol strains on RKN infection in tomato. For microbiome experiments, n = 8; for bacterial inoculation experiments, n = 11. The experiments were repeated twice with similar results. One-way ANOVA was conducted followed with Duncan’s new multiple range test (P < 0.05) to compare the difference in RKN infection with control and different microbial treatments. Significant differences (P < 0.05) across microbial treatments are indicated with lowercase letters
