A new disease was observed in sweet pea (<I>Lathyrus odoratus</I> L.) growing in greenhouses in Miyazaki Prefecture, Japan, in 2004. A <I>Fusarium</I> sp. that was highly pathogenic to sweet pea was isolated from the bases of sweet pea. On the basis of morphological tests performed using synthetic low-nutrient agar (SNA) and potato dextrose agar (PDA) cultures, the isolate was identified as <I>Fusarium oxysporum</I>. Further, the analysis of partial nucleotide sequences of the mitochondrial small subunit (mtSSU) rDNA and β-tubulin gene of the isolate confirmed the isolate to be <I>F. oxysporum</I>. This disease has not been reported in Japan till date. In foreign countries, <I>F. oxysporum</I> f. sp. <I>vasinfectum</I> can be seen as a pathogen causing sweet pea wilt in the "Index of Plant Diseases in the United States". However, the details of the disease remain unknown. Therefore, we propose the following common name for this disease: fusarium wilt of sweet pea ("sweet pea kabugare-byo" in Japanese). The isolate were also strongly pathogenic to common bean (<I>Phaseolus vulgaris</I>). The level of sensitivity to the pathogen varies depending on the cultivar of sweet pea.
