Inoculation of beneficial bacteria such as Bacillus velezensis strains has been widely used to stimulate plant growth and suppress the activity of fungal pathogens in agricultural fields including ginseng (Panax ginseng). However, there is little information on changing microbial abundances and community structure. In this study, we investigated the inoculum populations and pathogenic abundances (Rhizoctonia solani and Pythium ultimum) by quantitative real time PCR (qPCR) and the shift of bacterial communities by Illumina Miseq based on 16s rRNA gene in the soil cultivated with ginseng under the two different inoculation methods (drenching and seed soaking). The population of inoculated microbe (Bacillus velezensis CC112) has maintained its relevant proportion for 4 to 9 days during the experiment in a ginseng-cultivating soil. The abundance of pathogenic fungi was effectively suppressed by the application of the Bacillus strain against Rhizoctonia solani (39%) and Pythium ultimum (7%), respectively as compared to the control (no application) without altering significant bacterial community structure in a ginseng soil. The inoculation of B. velezensis CC112 maintained its abundance almost until two weeks after the inoculation without significantly altering bacterial community structures in a ginseng soil. Conclusively, the inoculation of beneficial microbes is capable of potentially suppressing plant pathogenic fungi and improving crop productivity in the field cultivated with ginseng, replacing agrochemicals.
