First report of Fusarium fujikuroi in the Lao PDR

The isolation of Fusarium fujikuroi from rice plants with elongated stems typical of bakanae disease in the Lao PDR is reported for the first time. The identification was based on both molecular and morphological markers. Koch's postulates were fulfilled. Bakanae disease has long been recognized in the Lao PDR based on symptomatology, but the etiology of the disease has not been clearly defined. This study was part of a continuing program to assist with the development of checklists of pathogens and plant diseases for Lao PDR for biosecurity purposes and integrated disease management.
