Abstract: A strain has a microorganism fertilizer efficacy and can be used as a biopesticide, by isolating multi-functional plant endophytic bacteria, which can widely suppress the growth of plant-pathogenic fungi and bacteria and specifically act on rice as a host plant, thereby retaining both a disease resistance inducing effect and a plant growth promoting effect, followed by mass-culturing and formulating. The present invention provides novel microorganism Bacillus oryzicola or Bacillus oryzicola having a DNA-DNA relatedness value of 70% or more with the Bacillus oryzicola.

Abstract: The present invention relates to a method for isolating a new microbial strain, belonging to Trichoderma spp., which is antagonistic to pathogenic bacteria of plant and naming the said strain as Trichoderma harzianum YC459(KCTC 0772BP), and for manufacturing a microbial pesticide for controlling properly plant diseases by using the above strain. This invention is greatly effective on controlling gray mold rot, damping-off, leaf mold and early blight as treating leaf of main crops or soil with the spore suspension of the said strain.
