Application research progress of biological control of tea diseases and pests

The control effect of chemical pesticides on tea diseases and pests is rapid, but its long-term use brings 3R issues directly affecting the sustainable development of tea. With the attention of tea quality and safety issues day, biological control as an important part of integrated pest management has turned into a broad prospect in the tea diseases and pests control system. This paper elaboratethed the definition and evolution of biological control, outlined the major types of biological control and their research on the application of tea, such as natural enemies of pests, botanical pesticides, microbial agents, pheromones and insect growth regulator, etc, summarized deficiencies of tea biological control, then proposed the following ideas and suggestions for biological control of tea diseases and pests院make full use of biocontrol microbes to antagonize tea pathogens, construct vectors against tea pest plant system, give full play to natural enemies of pests regulatory role for tea, strengthen research and bio-pesticides tea product development and application, to provide the reference for further research and application of biological control of tea diseases and pests.
