Fusarium wilt of bitter gourd (Momordica charantia) has been reported for the first time in Taiwan. Pathogenicity tests and reisolation from inoculated plants confirmed that a new forma specialis of Fusarium oxysporum was the incitant. The authors propose that this new forma specialis be named F. oxysporum f. sp. momordicae nov. f. Cross-inoculation tests with seven other formae speciales that exist in Taiwan indicated that only the present pathogen was able to incite wilt in bitter gourd.
