A novel Bacillus subtilis strain and use thereof for protecting the rust of plant roots

摘要

The present invention relates to a novel strain of Bacillus subtilis, and more particularly, to the B-5604 strain of Bacillus subtilis, which inhibits the growth of root rot pathogens, to a composition containing said strain or the culture medium thereof for controlling root rot pathogens, to a method for controlling ginseng root rot pathogens using said composition, and to a method for inhibiting the growth of Cylindrocarpon destructans or Fusarium solani using said strain. The microorganisms having antagonistic activity developed according to the present invention are not harmful to water and soil, and thus does not cause environmental pollution, and particularly, the microorganisms having antagonistic activity according to the present invention may not only reduce root rot pathogens in farmland in which ginseng is repeatedly cultivated or recultivated, but also alleviate root rot disease in ginseng being cultivated, thus significantly contributing to ginseng cultivation.
