(D) prevention and treatment of plant diseases and insect pests of medicinal plants in China, because of pests and diseases caused by the damage caused by a great loss, therefore, in-depth study of the occurrence and development of pests and diseases, good prevention and control work is to ensure the production of Chinese herbal medicines , To improve the yield and quality of medicinal materials, one of the key issues. In recent years, some achievements have been made in the prevention and treatment of medicinal plant pests and diseases. Such as the root antrum of Angelica, according to the cause of the disease, the use of highland cultivation, soil sterilization, the application of ash or lime powder and seeds treated with 0.05% of ammonium and other measures to prevent the occurrence of root rot. Lycium anthracnose (Glomerella cingulata shefSpauld) prevention and control of research, the use of Qingyuan and combined with agent control can control the occurrence of anthracnose. The pathogen of Gloeosporium Car-thami and the occurrence and development of disease have provided the theoretical basis for further prevention and cure of Anthurium andrantii. In addition, each
