Based on the author’s experience and lessons learned from the prevention and control of blast for many years, this paper puts forward the integrated prevention and control measures based on the selection and popularization of disease-resistant varieties, based on scientific fertilization and water management, and popularizes the province’s wards. Practice has proved that all counties (cities), social organizations and teams that conscientiously implement this comprehensive prevention and control measure have achieved remarkable results in increasing disease prevention and control. In the application of disease-resistant varieties of blast resistance in the process, the main problem is the loss of variety resistance, in order to explore ways to solve this problem, the author of the Zhenshan 97, Narrow Ye Qing 8, Red 410 and other large-scale promotion of this province Several resistance-resistant varieties of high yield of resistance to maintain the time, the cause of resistance were investigated and put forward five to prevent the loss of variety resistance and prolong the useful life of resistant varieties of measures.
