This paper deals with the wilt of Solanum melongena and its causal fungus Fusarium sp.
The Morphological and cultural characters of this fungus agree with the description of F. oxysporum (Schl.) Snyder et Hansen. This fungus causes a vascular wilt of Solanum melongena, but is not pathogenic on the other plants of Solonaceae, e.g. Lycopersicon esculentum, Nicotiana tabacum, Solanum tuberosum and Capsicum annuum. On the other hand, the various forms of F. oxysporum, that is, f. lycopersici, f. nicotianae, f. batatas, f. callistephi, f. conglutinans, f. lini, f. melonis, f. narcissi, f. niveum, f. pini, f. pisi, f. spinaciae, f. vasinfectum, f. cucumerinum, and the strains of F. oxysporum isolated from the root of wilted potato or the tuber of potato, etc. proved to be non-pathogenic on S. melongena. From these results, the writers propose the following name for the fungus.
Fusarium oxysporum (Schl) Snyder et Hansen, f. melongenae Matuo et Ishigami, nom. nov. Hab. in vivis Solani melongeni, cetera ut in typo.
The type culture is deposited in Fac. Text. Seric. Shinshu Univ., Ueda, Japan, which was isolated from Solanum melongena suffered from a vascular wilt disease.
