玉米粗缩病是由玉米粗缩病毒引起的一种玉米病毒病。属于植物呼肠弧病毒组,是一种具双层衣壳的双链RNA球形病毒,由灰飞虱以持久性方式传播。玉米粗缩病是我国北方玉米生产区流行的重要病害。而玉米大斑病是我国玉米主要产区的常见病害,给我国玉米种植业造成严重损失。随着抗病杂交种的推广和栽培制度的变更,大斑病危害一度得到控制,但由于大斑病菌生理小种多,变异速度快,我国部分地区大斑病危害有所回升。
Corn maize is a corn virus disease caused by maize rough virus. Belongs to the group of plant reoviruses and is a double-stranded double-stranded RNA helical virus transmitted by the Laodelphax striatellus in a persistent manner. Maize is one of the most prevalent diseases in maize production area in northern China. The maize leaf spot is one of the most common maize producing areas in China, causing serious damage to our country’s corn planting industry. With the popularization of disease-resistant hybrids and the change of cultivation system, the risk of maculopathis was controlled at one time. However, the phytoplankton of Quercus infestans was rapid and the mutation rate was high.
