[Isolation and identification of pathogen of seedling blight of Platycodon grandiflorum].
OBJECTIVE
To isolate and identify pathogen of the seedling blight occurred in Platycodon grandiflorum.


METHODS
The morphological observation, rDNA ITS sequence analysis, and Koch's postulates were used to identify the isolates of the causal agent.


RESULTS
The isolates of the causal agent was Rhizoctonia solani.


CONCLUSIONS
The result confirmed that R. solani is the pathogen of seedling blight of P. grandiflorum.
