Pythium spinosum Sawada에 의한 꽃도라지 뿌리썩음병의 발생
Occurrence of Lisianthus (Eustoma gradiflorum) Root Rot Disease Caused by Pythium spinosum Sawada
초록
A Pythium species was isolated from roots of lisianthus (Eustoma grandiflorum) showing wilt symptoms and reduced growth in a greenhouse at Ichon, Kyonggi-do in 1997. The Pythium species was identified as Pythium spinosum Sawada based on various mycological characteristics. The isolate was strongly pathogenic when inoculated to root of lisianthus plants in pots. The diseased plants showed typical symptoms of root and crown rot, resulting in reduced growth of roots and shoots, and consequently wilting of the above ground part of plants.
