บทคัดย่อ (EN): Rubber trees in China have suffered from many diseases or disorder. According to our survey, the number of diseases or pathogen-symptom combination on rubber trees accounted for more than 90. Four top economically important diseases or disorders in rubber trees in China are Powdery Mildew (Oidium heveae), Anthrocnose [Colletotrichum gloeosporioides (imperfect stage), Glomerella cingulata (perfect stage)], Brown Bast (Tapping Panel Dryness) and Root disease [Ganoderma pseudoferreum (Red Root Disease), Phellinus noxius (Brown Root Disease), Poria hypobrunnea (Black Root Disease), Rigidoporus linosus (White Root Disease), Helicobasidium compactum (Purple Root Diseas)]. Powdery Mildew occurred every year in China and resulted in serious premature leaf fall of rubber trees. Anthrocnose was the second important leaf disease, but more and more serious in during years, though it was occasionally spread some years ago. The incidence of Brown Bast is now more or less 15%, and no practical control measure yet. The incidence of Root Diseases is now at least 8% in Chinese rubber plantations. Among the root diseases, the most economically important ones are red and brown ones. The insignificantly important yet but potentially dangerous disease in Chinese rubber plantations are Corynespora Leaf Fall and White Root Disease. Corynespora Leaf Fall was newly discovered in nursery and still limited to few plantations. White Root Disease was discovered only in one plantation. Phytophthora diseases of rubber trees include abnormal leaf fall and Black Stripe on Tapping Panel. Abnormal leaf fall of rubber trees has been sporadically distributed in China. Black Stripe on Tapping Panel is now not economically important, though it was serious in Chinese rubber plantations some years ago.
