2006년부터 2007년까지 전북 남원시 운봉읍 화훼 재배 농가 단지에서 스타티스 줄기썩음병이 발생하였다. 병징은 지제부 부근의 줄기와 잎이 마르면서 갈색 또는 암갈색으로 변하며, 병이 진전되면 관부까지 갈변하다가 포기 전체 발병하여 고사한다. 병원균은 PDA에서 기중균사를 형성하고, 처음에는 흰색을 띠다가 연한 갈색으로 변하였다. 균사는 $90^{\circ}$로 분지하고, 대부분 하나의 세포에 다핵을 형성하였다. 또한 PDA에서 부정형 또는 타원형으로 $0.3{\sim}0.5\;mm$의 균핵을 형성하였다. 병원성 검정은 코흐의 가설에 따란 수행하여 병원성을 확인하였다. 본 연구에서 스타티스에 줄기썩음을 일으키는 병원균의 균학적 특징 및 형태적 특징을 조사한 결과, Rhizoctonia solani에 의한 스타티스 줄기썩음병으로 명명하고자 제안한다. Stem rot of perennial statice (Limonium sinuatum) was observed in Un bong, Jeonbuk from 2006 to 2007. Affected plants were randomly distributed in the greenhouses and infection rate was more than 10%. Stem and leaf of statice at soil line were dried and turned brown, initially. As the disease became severe, other stem parts and crowns were turned dark brown and then sunken. The fungal isolates were showed initially white aerial mycelium and turned brown with age. They produced few sclerotia which small, irregularly shaped with pinpoint sized. Mycelia were branched at $90^{\circ}$ angles and multinucleate in one cell. The pathogenicity of causal organism was proved according to Koch's postulates. The causal fungus of stem rot was identified as Rhizoctonia solani based on the cultural and morphological characteristics. This is the first report on stem rot of statice by R. solani in Korea.
