摘要： This is the first report of patch canker disease of rubber trees in China. It is characterized by discrete irregular patches of rotted, discolored bark and wood, accompanied by a decrease in latex flow. Pythium vexans was obtained from the diseased bark of the trunks and roots of rubber trees. Inoculating the fungus into healthy, mature rubber trees resulted in symptoms similar to patch canker and the same species was re-isolated from the diseased tissues. This is also the first record of Py. vexans in Hainan.
