Abstract
Stem rot of perennial statice (Limonium sinuatum) was observed in Unbong, 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 90o 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.
Key Words: Limonium sp. Rhizoctonia solani, Statice, Stem rot
