Abstract: Biocontrol strains were isolated from healthy grape rhizosphere soil collected from Xinjiang, Shandong, Hebei provinces. Four antagonistic strains showed good biocontrol activities against Botrytis cinerea on grape leaves and fruit by the plate test. Based on morphology and phylogenetic tree analysis, the strains(BF1-1、BF2-1、BF3-1 and BF4-1)were identified as Bacillus licheniformis, Bacillus amyloliquefaciens, Bacillus subtilis, and Bacillus cereus, respectively. The control efficacies of fertilizer made from the four strains were between 66.50%~85.68% in the field trial.

Key words: grape gray mold, biological control, Bacillus spp., control effect
