Advances in Integrated Control Techniques of Rice Blast.

Rice blast is the most devastating disease in rice, and it 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 food production safety. In the past decade, scientists have made great progress in the prevention and control techniques of rice blast, which paves the way for the green controlling of rice diseases.In this article, the advances in the intelligentization of rice blast field monitoring techniques, the optimization of prediction and forecast modeling system, the research and development of low-toxic and high-efficiency chemical pesticides, biogenic pesticides and inducers and the regulation of multiple ecological factors including variety and cultivation are reviewed, and the new strategies for green controlling of rice blast based on these techniques are summarized. Further, the problems such as high pesticide prices and pesticide residue faced by rice blast prevention and control and the challenge of slow research and development of low-toxic and economical biogenic pesticides are discussed. Finally, the development direction of green controlling of rice blast based on molecular targets, small interfering RNA（siRNA） and CRISPR/Cas9 technologies is predicted, with a view to guaranteeing the safety of rice production.
