Potato common scab, caused by Streptomyces scabies, is a severe plant disease that significantly reduces the economic value of potatoes worldwide. Biological control methods have proven effective in managing phytopathogens in various crops. Considering the importance of the disease, the present investigation was carried out to evaluate the efficacy of different native potent strains of Bacillus spp. against the common scab. In the present study, based on 16S rDNA sequence analysis, one isolate of Streptomyces scabies and six isolates of Bacillus were identified. Among these five isolates were Bacillus subtilis and one was Bacillus amyloliquefaciens. Screening through a dual culture assay showed that Bacillus subtilis (B4) and Bacillus amyloliquefaciens (B7) showed the highest inhibition percentages of 50.37% and 49.14 % respectively and produced biocontrol-relevant traits such as siderophores. In pot assays, the disease severity scab decreased from 63.89% (inoculated with S. scabies only) to 7.22 % when treated with B4 (Tuber Dip 15g ± Soil 3.5kg/25kg of FYM and inoculated with S. scabies). Similarly, in the field trial, the disease severity decreased from 55.56 % (inoculated with S. scabies only) to 8.33 % when treated with B4 (Tuber Dip 15g ± Soil 3.5kg/25kg of FYM). The talc-based bioformulation of Bacillus subtilis (B4), applied as Tuber Dip 15g ± Soil 3.5kg/25kg of FYM, effectively managed the common scab of potato and resulted in the highest yield.
