The faculty to produce fusaric acid in culture which is toxic to plant living cell was investigated by using the 25 strains belonging to 6 sgecies of the genus Fusarium. In F. oxysporum and F. maniliforme all the forma specialis were positive, but the other four Fusaria employed in the present experiment were negative.
It might give an interesting problem in the study of pathological wilt-mechanism in pinat, that all the Fusarium belonging to oxysporum and moniliforme, have the faculty of fusaric acid production and then cause a systemic fusariose as wilting or damping off of host plant Moreover, application of investigating the faculty to produce such specific metabolite as fusaric acid in culture will be help in studying species relationship in Fusaria.
