Southern blight of ginger [Zingiber officinale (Willd.) Roscoe] occurred on Hachijo Island of Tokyo Metropolis in 2012. A pathogen isolated from the diseased plants was identified as Sclerotium rolfsii Saccardo based on morphological characteristics as well as molecular analyses of the rDNA-ITS region. An inoculation test confirmed that the fungus was a causal agent of this disease. This is the first report of the disease in Japan.
