| Abstract: | A new disease, found on fan columbine in August of 1997, first appeared as necrotic spots on leaves and within a week caused
wilting of all the leaves. Fungal mycelia bound aerial parts of the plants together, formed mats of mycelia and eventually
killed the plants. The pathogen, isolated from the infected leaves and stalks, was identified as Rhizoctonia solani AG1-IB in respect to hyphal anastomosis and culture types. The common name of web blight is proposed for this new occurrence
on fan columbine (Kumonosu-byo in Japanese).
