Abstract

Defoliation, dieback and massive mortality of Lansium tree (Lansium domesticum Corr.) in Ogan Komering Ulu (OKU) Regency, South Sumatera Province was first noticed in 2014 and caused substantial economic losses to duku fruit production. The disease prevailed along Ogan riverside on the trees after being scratched by a squirrel. A Ceratocystis species was consistently recovered from the infected branches, stem and taproot. Koch's postulates were fulfilled by inoculating the mycelial plug of fungus onto the stem and braches of Lansium tree. The morphology of teleomorph and anamorph were similar to that of C. acaciivora. Blast searches of ITS and TUB region in GenBank indicated that isolates are grouped within the C. fimbriata sensu lato species complex.
