Bacillus strains with potential for growth promotion and control of white mold in soybean

Plant growth-promoting rhizobacteria (PGPR) are known to stimulate the biocontrol of phytopathogenic bacteria and fungi, induce plant growth, increase yield important economic crops. In this study, we evaluated in vivo, ability Bacillus strains control soybean white mold disease promote growth plants under greenhouse conditions. Initially, 27 were analyzed by PCR for presence genes encoding antimicrobial molecules, followed vitro tests positive against four Sclerotinia sclerotiorum, Macrophomina phaseolina, Rhizoctonia solani, Colletotrichum truncatum. The bacterial that returned results vivo their promoting capacity cultivars Potencia RR M6210 IPRO, plants. showed eight presented bamD, ituD, fenF, while bacAB gene was observed 16 all tested strains. experiment inoculation strain VBN02 best treatment increasing fresh shoot biomass IPRO cultivar single relation (111.9% 103.57%, respectively). Co-inoculation inoculant VBE01 superior root mass both cultivars. Two other strains, VBE05 VBE01, reduced progression 39.1% 37.5%, respectively. conclusion, our have potential
