Abstract: The domestic and overseas literatures about diseases in Carya illinoensis were collected, and the species, pathogen, damage characteristics and bio-control of diseases in Carya illinoensis were summarized. There are 21 species diseases in Carya illinoensis, including 16 fungal diseases, 3 bacterial diseases and 2 nematode diseases. There are 8 main diseases and in which scab, powdery mildew and melasma have the most serious harm. Nowadays leaf scorch,crown gall,bunch,root knot nematode and dagger nematode have not been found yet at home.But the harm in foreign countries was serious,it should be got attention as quarantine disease. In recent years, the domestic pathogenesis trend of increased significantly. It caused serious harm to the trunk of many kinds of Carya illinoensis whose age were over 5-year-old and it often lead to the death of the whole tree. Zonate spot and maldel secco mostly belonged to weak parasitic fungal diseases; the harm of it was slight.The paper aims at providing theoretical guidance for control of the disease of Carya illinoensis.
