Abstract:

China is one of the most serious countries damaged by crop pests in the world and more than 1700 species occur annually. In recent years, due to the global climate change and economic integration, crop structure adjustment and other factors, China’s crop diseases and insect pests tend to be serious. Chemical pesticides are the most important means to control crop diseases and insect pests in China. A large number of pesticides are used to control crop pests, but also bring a series of problems, such as pesticide residues, environmental pollution, pest resistance and resurgence. Therefore, it is the core task of Chinese plant protection scientists to develop green prevention and control technology and reduce the amount of chemical pesticides. Its key development directions include: effects of crop structure adjustment, global economic integration and climate change on population succession of major diseases and insect pests; new theories, methods and products of plant protection based on modern biotechnology, information technology, new materials and advanced manufacturing; key technologies and products of green prevention and control; precise application, residue detection and traceability technology for chemical pesticides; intelligent plant protection equipment; and the green sustainable control model of regional diseases and insect pests.

Key words: Crop Diseases and Insect Pests, Chemical Pesticides, Green Prevention and Control, Science and Technology Development
