Abstract: According to the history data on occurrences of rice bacterial blight collected from national incidence(1960 to 2016 year), Zhejiang (1987 to 2016 year), Guangdong, Hainan, Jiangsu and Anhui Provinces (1987 to 2014 year), southern and eastern China were thought to be the endemic areas of rice bacterial blight. The disease was most prevalent during the 1970s-1990s but just occurred intermittently from the mid and late 1990s to 2010. In recent years, the disease re-occurred in some regions and displayed a prevalent trend, becoming a potential regional risk. By analyzing the relationship of disease occurrence with bacterial sources, rice cultivars, climate conditions, water and fertilizer management, the main factors affecting disease epidemics were discussed and the method of systematic prediction and forecast was simplified, and also put forward a method of "two check two rules governing”. High effective agricultural chemicals such as Zinc thiazole, Thiodiazole-copper, Thio copper and so on were selected. The study proposed a green integration method for effectively control the disease, which included the early monitoring and forecast, promotion of resistant varieties, seedling control, water and fertilizer management, emergency prevention and control using agricultural chemicals. These measures were applied in large area of rice production for effectively controlling the disease in China.

Key words: rice bacterial blight (RBB), monitoring and early warning, high effective agricultural chemical, green prevention and control
