Abstract

    The abnormal inflorescences can frequently be spotted on mango trees in Taiwan. It occurs at the juvenile stage of fruit after the blossom. The symptom is characteristic to the well-known mango malformation disease (MMD), which is caused by Fusarium species. However, it was erroneously considered to be physiological obstacle by farmers. Consequently MMD has not been officially reported in Taiwan. To determine the causal agent of the abnormal inflorescence on mango trees, pathogen isolation and then Koch’s postulate have been conducted. It is ascertained to be mango malformation disease, which is firstly reported in Taiwan. Based on morphological and molecular analyses, the pathogen occurring in Taiwan has been identified as F. mangiferae.

Key words: mango malformation disease, Fusarium mangiferae
