Turkish Journal of Agriculture and Forestry

Bacterial spot disease caused by Xanthomonas axonopodis pv. vesicatoria (X. axonopodis pv. vesicatoria) is a devastating pepper (Capsicum annuum) disease in Turkey. Biological control of Xanthomonas axanopodis pv. vesicatoria is of great interest, in terms of environmental safety and economic return. In this study, 3 Bacillus strains isolated from soil samples of the rhizospheres of peppers grown in greenhouses and fields were used to suppress the size of the population of X. axonopodis pv. vesicatoria. Results indicated that disease development decreased by 11%-62% and 38%-67% in pepper plants inoculated with the 3 Bacillus strains alone and in combination, respectively, in …
