Abstract: The disease investigation was carried out in six artificial planting areas and two wild distribution areas of Malania oleifera in Guangnan county, Wenshan county, Yunnan province, which was the origin and distribution center of Malania oleifera in China, and three planting areas and one wild distribution area with serious disease were selected for the study of the control effect. The results showed that leaf spot, root rot and stem rot were the main diseases in the artificial planting area of Malania oleifera in Guangnan county, while plaster disease was the primary disease in the wild distribution area. Additionally, 50% carbendazim had ideal control effect on leaf spot, and 47% kasugamycin·copper oxychloride was better than 80% bordeaux mixture for the control of plaster disease.
