RL-1-178 in suppressing Sclerotium root and stem rot
of chili pepper was approximately equal to that of
Trichoderma harzianum NR-1-52 or that of carboxin
treatment. S. mycarofaciens SS-2-243 and S. philanthi
RL-1-178 suppressed Ralstonia wilt of chili
pepper in a way that was similar to streptomycin
sulfate treatment and it was observed that T. harzianum
NR-1-52 had no effect on the bacterial wilt.
Under field conditions where the soil was inoculated
with two pathogens, the results showed that S. philanthi
RL-1-178 could protect the chili pepper plants
from S. rolfsii and R. solanacearum infection better
than S. mycarofaciens SS-2-243 or T. harzianum
NR-1-52. S. philanthi RL-1-178 treatment resulted in
58.75% survival of chili pepper plants and its efficacy
was not significantly different from the carboxin-andstreptomycin
sulfate treatment.
