Blue mold of tomato caused by Penicillium oxalicum in Japan

2009

In 2006, stem rot and blue-green crusty lesions were found on the stems of tomato plants in Chiba Prefecture, Japan. Penicillium oxalicum was isolated repeatedly from the diseased plants. The causal fungus reproduced natural symptoms after artificial inoculation of tomato plants and was re-isolated from symptomatic plant tissue. P. oxalicum is a new pathogen that causes blue mold on tomato plants in Japan.
