A new disease was found on Vernicia fordii with symptom of root rot in Dushan, Guizhou Province. The disease occurred most seriously at growth stage (May to July), primarily affecting the roots. The diseased plants initially showed wilting and leaves fade green to withered until plant death. The fungal community composition of the rhizosphere soil was analyzed from healthy and diseased plants. The result showed that mainly dominant phyla and genera in the rhizosphere soil of diseased and healthy plants were similar, but the relative abundance was absolutely different. Moreover, the genus Fusarium causing a wide range of plant diseases only appeared in the fungal community of rhizosphere soil of diseased V. fordii, with relative abundance accounting for 2.44%. The pathogens were isolated and purified through tissue isolation. Ten strains were isolated from the healthy junction of V. fordii rhizome suffering from typical root rot. Among them, strain AX-2 induced typical symptoms of root rot after being back-inoculated to the seedlings of V. fordii. The pathogen was subsequently isolated from the roots and stems of diseased plants. Its morphological characteristics were found to be consistent with those of the pathogen isolated from the field. Molecular identification further verified that this strain was identical to AX-2. Morphological characteristics and multi-loci (ITS+tef1-α+rpb2+CaM+tub2) phylogeny classified AX-2 as Fusarium foetens. The species is firstly reported as the pathogen of root rot in V. fordii. This study provides a theoretical foundation for investigating the infection characteristics and control strategies of root rot disease in V. fordii.
