Objective:
The research focused on identification the pathogen of Aquilaria sinensis dieback disease and confirmation the function of inducing agarwood formation by fungi.
Method:
The morphological observation, rDNA ITS sequence analyses, Koch's postulates and pathogenicity test were used to identify the isolates.
Result:
The isolates of the causal agent was Lasiodiplodia theobromae, which induced the plant to produce highly valuable agarwood.
Conclusion:
The first report of dieback disease of Aquilaria sinensis caused by L. theobromae, and our research results laid a theoretical foundation for agarwood production by using fungus.
