Bulb Rot of Sandersonia aurantiaca Caused by Fusarium anguioides and Fusarium sp. Intercepted at Plant Quarantine in Japan

摘要

A new disease of Sandersonia aurantiaca Hook, causing bulb rot was intercepted at plant quarantine inspection at Narita International Airport in July 2005， June 2006, and August 2007. The isolated fungi were pathogenic to the original host and were identified as F. anguioides Sherb. and Fusarium sp. (within the Fusarium aven-aceum species complex), based on the morphology, cultural characteristics, and phylogenetic analyses of the partial P-tubulin gene and TEF-la gene. This is the first report of this disease in Japan.
