A 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 comp.. View More»
