| 摘 要： | 2009年,南方水稻黑条矮缩病在湖南省大面积暴发,造成严重的经济损失。根据2008-2009年湖南省道县、汉寿县两地区的田间发病率、传毒介体的种群消长动态、药剂防治情况调查,结合2009年两地区稻飞虱带毒率测定,初步分析结果表明,水稻苗期至分蘖期传毒介体量大、品种感病是2009年湖南省南方水稻黑条矮缩病暴发的部分原因;同时,值得注意的是需要防范该病害在来年扩展危害。

| Abstract: | The south rice black streaked dwarf disease broke out and caused severe yield loss in Hunan in 2009. A primary analysis of yield loss, population dynamics of rice planthopper, pesticide usage in Hanshou and Dao counties in 2008-2009 and virulence ratio of rice planthopper in 2009 revealed that this disease burst out in Hunan in 2009 partly due to the large population numbers of virus vectors in seedings at tillering stage. It is therefore crucial to prevent extension of this disease in the following year. |
