dc.description.abstractEnA collection of 25 rhizobacterial strains, recovered from rhizospheric soils around healthy tomato plants grown in Rhizoctonia-infested fields, belonging to Bacillus amyloliquefaciens, B. thuringiensis, B. megaterium, B. subtilis, Enterobacter cloacae, Chryseobacterium jejuense, and Klebsiella pneumoniae was screened for its suppressive effects of Sclerotinia Stem Rot of tomato caused by Sclerotinia sclerotiorum and plant growth-promoting ability. The inhibitory effects of diffusible and volatile metabolites from these rhizobacteria against pathogen mycelial growth depended significantly upon strains tested. Growth inhibition caused by diffusible and volatile compounds was of about 37-57% and 24-54%, respectively. All strains tested had totally suppressed myceliogenic germination of sclerotia and improved germination of bacterized tomato seeds as compared to the untreated controls. The screening of their disease-suppressive and plant growth-promoting abilities revealed 72-100% decrease in Sclerotinia Stem Rot severity and significant increments in plant height by 52-67%, roots fresh weight by about 66-88% and aerial part weight by 47-75%, compared to S. sclerotiorum-inoculated and untreated control. The most promising strains combining disease-suppressive and growth-promoting abilities were B. subtilis B10 (KT921327) and B14 (KU161090), B. thuringiensis B2 (KU158884), B. amyloliquefaciens B13 (KT951658) and B15 (KT923051), and E. cloacae B16 (KT921429).
