水稻黑条矮缩病、条纹叶枯病是江苏省水稻上的两种主要病毒病,近年来采取多种防控措施后危害得到有效控制。由于今年两种病毒病的传毒介体灰飞虱发生量大、带毒率高,部分地区感病品种种植面积大,因此仍要加强防治这两种病毒病。此外,南方水稻黑条矮缩病去年在该省也已查见,预计今年流行范围将扩大,增加了病毒病发生种类,防控难度加大,应引起重视。
Rice black-streaked dwarf and striped leaf blight are the two major virus diseases on rice in Jiangsu Province. In recent years, the prevention and control of various diseases have been effectively controlled. Due to the large amount of Laodelphax striatellus which is transmitted by two kinds of virus diseases this year, the high virulence rate and the large planting area of susceptible cultivars in some areas, it is still necessary to strengthen prevention and control of these two virus diseases. In addition, the southern rice black-streaked dwarf disease has also been seen in the province last year. It is estimated that the epidemic area will be expanded this year, increasing the types of virus diseases and increasing the degree of prevention and control, which deserves our attention.
