Chinese Herbal Medicine Resources with Bacteriostatic and Insecticidal Activities and Their Application as Pesticides

Herbal pesticides refer to the active ingredients extracted from herbs which are used for pest and disease control in crops or pure substances isolated from them. They are of great significance for the production of pollution-free agricultural products, as well as for exploiting the abundant plant resources in China for the prevention and control of pests.
