Chestnut is a high valued economic orchard crops in Guangdong mountain area. A new disease on the leaves of chestnut was found in chestnut orchard of SCAU and areas where chestnut grows in Guangdong. Its symptom was different with those any reported leaf disease on chestnut. The pathogen was identified as Colletotrichum gloeosporioides, and is the same as the pathogen of Coniella castanicola, anthracnose of Camellia oleifera and Caryota ochlandra.
