3-year-old plants of Castanea mollissima were found with leaf discolouration, wilting, and stunted growth associated with severe root rot in several commercial nurseries in Jianou, Fujian, China. Five Phytophthora-like isolates were isolated from necrotic taproots and identified as Phytophthora cinnamomi on the basis of morphological characteristics and molecular analyses. Pathogenicity tests were carried out and Koch's postulates were fulfilled. This is the first report of Phytophthora root rot of C.mollissima caused by P. cinnamomi in China.
