Abstract

The objective of this research was to identify bacterial spot-causing pathogen and bacterial antagonists for management of the disease using biocontrol agents as environmentally friendly alternatives. Isolates of Bacillus spp. were obtained from the soil samples collected at different localities in Serbia. Antibacterial activity of natural antagonists toward the pathogen isolated from infected pepper leaves was examined using a modified well-diffusion assay and standard germination test. Our results confirmed the presence of Xanthomonas euvesicatoria as the causal agent of bacterial spot of pepper. Screening of 32 Bacillus spp. isolates for antibacterial activity showed that 8 isolates inhibit growth of examined X. euvesicatoria isolates. Four isolates identified as Bacillus subtilis exhibited the highest antibacterial activity by in vitro test (from 5 to 14 mm inhibition zone of bacterial growth). The isolates positively influenced germination of pepper seeds, causing up to 16% and 70% increase in germination and germination viability compared to control seeds infected with pathogen. The most effective isolates of Bacillus subtilis could be used as potential biocontrol agents of bacterial spot of pepper.
