【 摘 要 】

A serious root rot disease in nurseries and plantations of J. curcas has been observed in Luodian County, Guizhou Province, China, since 2006. The symptoms were yellowing, wilting and leaf fall as well as blackening and rotting of the roots and collars. Laboratory examination and greenhouse pathogenicity tests showed that the causal agent of the disease was Nectria haematococca. This is the first report of N. haematococca, as the cause of root rot of Jatropha curcas L. in China.
