Advances in Integrated Prevention and Control Techniques of Rice Blast

Rice blast is the most devastating rice disease, which seriously threatens the safety of rice production. Improving the ability of integrated prevention and control of rice blast has always been an important part of ensuring the safety of food production. In the past 10 years, scientists at home and abroad have made great progress in the prevention and control techniques of rice blast, paving the way for the green and safe prevention and control technology of rice diseases. This article reviews the research progress of intelligentization of rice blast field monitoring technology, optimization of predictive and forecast data modeling system, research and development of low-toxic and high-efficiency chemical pesticides, biogenic pesticides and inducers, and regulation of multiple ecological factors of varieties and cultivation, summarizes new strategies for green prevention and control of rice blast based on these techniques, discusses the problems of high pesticide prices and pesticide residues in the prevention and control of rice blast, and looks forward to the development direction of green prevention and control technology based on molecular targets, small interfering RNA (siRNA), CRISPR/Cas9 and multiple factors.
