Rice blast is a destructive and epidemic disease of rice. Analysis from the history of Guizhou: the prevalence of rice blast, the loss of variety resistance and the unreasonable layout are the main factors. The broad source of bacterial sources is the basis for proper climate and human activities Reasonable is the main condition. According to the characteristics of paddy field ecosystem in Guizhou, from 1995 to 1998, through the screening of supporting technologies, the deepening test of individual technologies and the standardization of technical assembly, the government has formulated and implemented the guidelines of “strengthening the dynamic monitoring of disease, promoting resistant varieties and implementing fitness control Cultivation, scientific use of drugs, demonstration driven, comprehensive prevention and control ”of the management strategy, the implementation of comprehensive management of an area of 87.24 million hm2, restore paddy 718,200 t, and achieved significant economic, social and ecological benefits, and concluded that“ the comprehensive prevention and control of rice blast in Guizhou Province Technical operation rules ”
