摘要: 通过收集整理中国1960—2016年、浙江省1987—2016年和广东、海南、江苏、安徽省1987—2014年水稻白叶枯病发生的历史资料,明确了华南、华东为中国水稻白叶枯病常发流行区。20世纪70—90年代初为病害重发流行期,90年代中后期至2010年为间歇流行期;近年来病害发生流行又趋上升,区域性流行潜在风险加大。通过探讨分析菌源、品种、气候、肥水管理与病害发生的关系,明确了影响病害发生流行的主要因素,简化了系统测报方法,提出了“二查二定”办法。筛选出噻唑锌、噻菌铜、噻森铜等对口高效防治药剂,集成提出了以监测预警预报为基础,抗性品种推广为前提,秧田防治为关键,科学肥水管理和药剂应急防治相结合的水稻白叶枯病绿色防控技术,生产上大面积推广应用,有效控制了病害的发生。

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
