have been shown to effectively control R. solani. However, few reports have been published that document the ability of Bacillus pumilus (B. pumilus) to control damping-off disease.
The successful survival and colonization of beneficial antagonists are essential for the biocontrol of diseases caused by soil-borne pathogens. Previous reports have demonstrated that the control efficiencies of Pseudomonas spp. and Bacillus spp. were directly related to the ability of these microbes to colonize roots ( Cavaglieri et al., 2005 and Ji et al., 2008). However, the population dynamics and colonization pattern of B. pumilus in situ has not been studied in detail
