柑桔黄龙病是全球蔓延为害面积大、迄今仍然只能防控而不可根治的危险性柑桔病害。近年来,受暖冬频发、传播病害的越冬柑桔木虱数量增多,以及未经检疫的带病苗木随着柑桔产业的快速扩张而大范围种植等因素的影响,柑桔黄龙病呈现出暴发式流行态势。本刊记者对广东、广西、浙江、福建、湖南与江西赣南等地柑桔黄龙病发生为害与防控情况的采访调查表明,尽管近年一些产区柑桔黄龙病为害趋重,但仍处于可控状态,黄龙病为害面积占我国柑桔生产面积的比重仍然很低,生产中推广的“三板斧”仍然是最有效的防控措施。对于柑桔黄龙病防控,要树立打赢持久战的信心,高度重视,统一思想,创新产业发展模式,以生产效益的提升来增强生产者的防控积极性、主动性;全国联动,加强疫情监测和苗木市场监管;区域协调,全力推广柑桔木虱的统防流治,有效切断柑桔黄龙病传播蔓延途径,将黄龙病对我国柑桔产业造成的危害控制在最低水平。
Citrus Huanglongbing is a large area of global spread damage, so far still only control and not cure the risk of citrus disease. In recent years, the number of overwintering citrus psylla frequently affected by heating in winter increased, and that of diseased seedlings not quarantined along with the rapid expansion of citrus industry and other factors, citrus Huanglongbing showed Outbreak pandemic. Interview surveys of the occurrence and prevention and control of citrus Huanglongbing in Guangdong, Guangxi, Zhejiang, Fujian, Hunan and Jiangxi Gannan of Jiangxi showed that although citrus Huanglongbing is becoming more and more harmful in some producing areas in recent years, Controllable state, Huanglongbing damage area accounting for the proportion of China’s citrus production area is still low, the production of the promotion of “three axes” is still the most effective prevention and control measures. For the prevention and control of citrus Huanglongbing, it is necessary to establish the confidence to win a protracted war, attaches great importance to unifying ideas and innovating the industrial development model, and enhancing the producer’s prevention and control motivation and initiative with the enhancement of production efficiency. The nationwide linkage strengthens the epidemic Monitoring and nursery stock market regulation; regional coordination, to promote the general prevention and treatment of citrus psyllid effectively cut off the route of transmission and spread of citrus Huanglongbing, Huanglong disease on the citrus industry in China to minimize the harm caused.
