Erwinia carotovora subsp. carotovora에 의한 비트 세균성 무름병

Bacterial Soft Rot of Beet by Erwinia carotovora subsp. carotovora

Bacterial soft rot caused damage to beets massively grown in Pyungchang, Kangwon province, Korea. The affected roots and stems became cream colored and slimy, and turned black, causing the plants to become wilt and die. The casual organism isolated from the infected plants was identified as Erinia carotovora subsp. carotovora based on physiological and biochemical characteristic, and the results of the Biolog program (Biolog Inc., U.S.A.). E. carotovora subsp. carotovora is the first discribed bacterium which causes bacterial soft rot on beet in Korea.
