description <i>Alocasia longiloba</i> is a popular ornamental plant in China, however pests and diseases associated with <i>A. longiloba</i> reduce the ornamental value of this plant. From 2016 to 2021, stem and root rot has been observed on <i>A. longiloba</i> in Guangdong Province, China. Once the disease became severe, plants wilted and died. A fungus was isolated from the diseased stem and identified as <i>Fusarium elaeidis</i> using both morphological characteristics and molecular analysis of DNA-directed RNA polymerase II subunit (<i>rpb2</i>), translation elongation factor-1α (<i>tef1</i>) gene and β-tubulin (<i>tub2</i>) sequence data. The pathogenicity test showed the fungus was able to produce typical symptoms on <i>A. longiloba</i> similar to those observed in the field. The original pathogen was reisolated from inoculated plants fulfilling Koch’s postulates. This is the first report of <i>Fusarium elaeidis</i> causing stem rot on <i>A. longiloba</i>. These results will provide a baseline to identify and control diseases associated with <i>A. longiloba</i>.
