Abstract
P. wasabiae was isolated from discolored seeds of wasabi(Wasabia japonical Mtsum.) and inoculated to fresh seeds, then the effect of fungicides on suppression of diseases were determined. Emergence rate of wasabi seeds where suppressed to 52.5% by the inoculation and it reached up to 92.7% by dipping treatment of inoculated seeds ito benomyl solution. The incidence rate of black leg disease and damping off were 32.0 and 22.0%, respectively, in control treatment that sown in the soil inoculated with P. wasabiae. But dipping treatment of inoculated seeds into benomyl solution resulted in 12.0% and 10.7% in incidence rate of those two diseases, respectively.
