Erwinia rarotovora subsp carotovora에 의한 콩나물 무름병 발생을 인위적인 조건하에서 조사하였다. 콩나물의 재배 온도가 콩나물 무름병 발생과 생장에 미치는 영향은 3$0^{\circ}C$이상의 고온에서 무름병 발생율이 높아졌으며 35$^{\circ}C$에서는 약 22%의 발병율을 나타내었다. 종피와 자엽 부위에 인위적인 상처를 낸 경우 70%이상의 발병율을 보였으며 콩나물의 신장을 억제하였다. 습도는 90%이상 유지시 33%의 발병율을 보였으며 콩나물의 생장을 억제시켰다. 콩나물 재배 배출액을 관수액으로 재이용하였을 때 무름병의 발병율이 증가하였다.

Incidence of soybean sprout rot by Erwinia carotovora subsp. carotovora was examined under several artificial conditions. Under higher temperatures over 3$0^{\circ}C$, disease incidence was increased and the rate of soft rot incidence was 22% at 35$^{\circ}C$. Artificial injuries of inner cotyledon and seed coat induced the disease above 70% and inhibited the soybean sprout growth. Relative humidity above 90% increased the soft rot to 33% and inhibited soybean sprout growth. When the leaked water collected from soybean sprout was reused for irrigation, the disease incidence was increased.
