近年来在福建省南平市延平区南方水稻黑条矮缩病的发生为害日趋频繁,特别是近年来传毒媒介带毒白背飞虱的大量迁入,导致该病在本区普遍发生。白背飞虱一旦获毒便可终身带毒,若虫、成虫均能传毒且传毒效率极高。白背飞虱持久性传毒且水稻各生育期均能感病。经过几年来的探索,结合本区南方黑条矮缩病发生规律及特点,并结合当地气候特征,提出该病的防控对策,以期为水稻南方黑条矮缩病的防控提供参考。
In recent years, it is more and more frequent that the occurrence of black-streaked dwarf rice in southern China in Yanping District, Nanping City, Fujian Province has become more and more frequent. Especially in recent years, large numbers of poisonous vector-borne white-backed planthoppers migrate in, resulting in the widespread occurrence of the disease in this area. Whitebacked planthopper can be life-long poisoned once it has been poisoned, nymphs and adults can be highly toxic and highly toxic. White-backed planthopper long-term transmission of toxic and susceptible to rice in all growth stages. After several years of exploration, combined with the occurrence of southern black stripe dwarf disease and its characteristics, combined with the local climate characteristics, put forward the prevention and control measures of the disease, in order to provide a reference for the prevention and control of southern black stripe dwarf disease.
