Fusarium elaeidis Causes Stem and Root Rot on Alocasia longiloba in South China

Alocasia longiloba is a popular ornamental plant in China, however pests and diseases associated with A. longiloba reduce the ornamental value of this plant. From 2016 to 2021, stem and root rot has been observed on A. longiloba in Guangdong P...
