水稻细菌性基腐病1983年在我市“两晚”稻生长后期爆发,据不完全统计,全市发病面积7.28万亩。1984年发病范围和面积进一步扩大,7月上、中旬就出现发病高峰,单季晚稻分蘖盛期,明显发病面积10.55万亩,其中严重的4000亩左右。水稻生长后期统计,全市发生“青枯”面积27.47万亩,其中严重的1113亩,估计因病损失稻谷1109.3万斤。水稻细菌性基腐病已是该市目前水稻生产上的一大潜在威胁。
Bacterial base rot disease in 1983 in our city, “two nights” outbreak of late rice growth, according to incomplete statistics, the city’s incidence of 72,800 acres.

Late rice growth statistics, the city occurred “green dead” area of 274700 acres, of which 1113 acres of serious, estimated loss of 11.09 million kilograms of rice due to disease.
