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.

변색된 종자에서 분리된 P. wasabiae에 접종된 종자는 평균 52.4%의 낮은 발아율을 보였으나 benomyl 침지처리에 의해 발아율이 83.3%로 향상되었다. 멸균 토양에 파종된 접종종자는 28.0%의 먹들이병, 12.7%의 모잘록병 발병률을 보였으나, benomyl로 침지처리된 종자는 먹들이병 6.0%, 모잘록병 4.7%의 낮은 발병률을 나타냈다. P. wasabiae가 접종된 토양에 공시 약제로 처리된 종자를 파종한 결과 먹들이병 발병률은 약제를 처리하지 않은 종자의 32.0%에 비해 benomyl 침지처리에서 12.0%로 발병이 억제되었고, 모잘록병은 10.7%의 가장 낮은 발병률을 보였다.
