Biocontrol efficiency of Bacillus velezensis GSBZ09 on grape white rot caused by Coniella vitis. (A,C) (a1,b1) Inoculated with C. vitis; (a2,b2) LB broth; (a3,b3) culture of GSBZ09, (a4,b4) culture filtrate of GSBZ09; inoculated with C. vitis 24 h after inoculation with the culture (a5, b5) and culture filtrate (a6, b6) of GSBZ09; inoculated culture (a7,b7) and culture filtrate (a8,b8) of GSBZ09 24 h after inoculation with C. vitis. (B,D) Incidence, disease index and control efficiency of B. velezensis GSBZ09. Error bars represent the means ± standard deviation. Ten biological replicates were performed for each treatment, and the experiments were independently repeated three times. Different letters above the bars indicate a significant difference at p < 0.05 according to Duncan’s multi-range test.
