玉米粗缩病是危害玉米生产的一种重要病毒病，历史上曾有几次大发生，近几年又呈上升趋势。引起该病害的病毒属于呼肠孤科斐济属。主要由灰飞虱以持久性方式传播。毒源、介体、品种是病害发生的必要条件，三者都达到一定的程度、数量则会引起病害流行。影响这三个条件的因素是多方面的，包括气象因素、耕作栽培措施、栽培感病品种等。针对这些因素提出压低毒源、虫口密度并种植抗耐病品种的综合防治措施 Maize is one of the major viral diseases that endanger the production of maize. There have been several major occurrences in history and the trend has also been on the rise in recent years. Viruses that cause the disease belong to the genus Fiji of the reticulata. It is mainly transmitted by Laodelphax striatellus in a persistent manner. Toxic sources, mediators and varieties are the necessary conditions for the occurrence of diseases. All three have reached a certain level, and the quantity will cause the epidemic. Factors affecting these three conditions are manifold, including meteorological factors, tillage and cultivation measures, cultivation of susceptible varieties and so on. According to these factors, we put forward the comprehensive prevention and control measures to reduce the density of poison and insect population and plant resistant varieties
