Betel vine (Piper betle) is one economically important medicinal plants of Thailand. It is widely cultivated in the North-eastern Eastern and Central parts of the country. However, there are many problems to be overcome before maximum yield can be approached. Disease damage to the crop is one of several known limiting factors. The major disease is foot rot (Phytophthora parasitica); it can cause extremely heavy losses throughout the growing areas. Other diseases are : Rhizoctonia root rot (Rhizoctonia solani), Sclerotium wilt (Sclerotium rolfsii), Pythium root rot (Pythium splendens), anthracnose (Colletotrichum dasturii), Phoma leaf spot (Phoma sp.) powdery mildew (Oidium piperis), bacterial leaf spot (Pseudomonas betle), mosaic (virus) and root knot (Meloidogyne incognita). Effective control measures are also recommended.
