Abstract
In autumn 1994, we isolated Phoma lycopersici from brown lesions on tomato leaf, stem and fruit in Takachiho, Miyazaki, Japan. The fungus produced round lesions on tomato leaves, petioles, stems and fruits by artificial inoculations using adult and juvenile plants. In Japan, P. exigua, P. lycopersici and P. destructiva have been reported as the pathogen of tomato leaf spot, stem rot and fruit rot, respectively. We propose that P. lycopersici also causes leaf spot and fruit rot of tomato, and that the tomato diseases caused by Phoma species should be called by a unified name.
