据不完全统计,全世界有40多种玉米病毒病。以玉米矮花叶病、玉米粗缩病和玉米条纹病等分布最广、危害最严重。为了解决玉米病毒病防治问题,美国俄亥俄州立大学曾先后主持召开几次国际玉米病毒病防治研究学术讨论会,交流、讨论玉米病毒病的发生分布、病原鉴定、介体传播、流行规律、病毒提纯、抗血清制备、抗性鉴定及防治措施等,促进了国际玉米病毒病防治研究进展。我国1954年前后,新疆南疆17个县市玉米条纹矮缩病普遍发生,成为当地玉米生产中的严重问题;1963年上海、浙江、江苏水稻黑条矮缩病毒侵染玉米,造成玉米严重减产,有人称其为玉米粗缩病;1968年,河南新乡、安阳夏玉米发生玉米矮花叶病,造成毁灭性损失,并逐渐蔓延至山西、河北、陕西、甘肃、山东等省,成为玉米产区的重要病害;1969年甘肃敦煌玉米条纹矮缩病严重发病,严重地块颗粒无收;1977年河北省玉米粗缩病大面积流行;1980年以来,甘肃、陕西、山西等省大面积发生玉米红叶病;1988年以来,四川南充地区9
According to incomplete statistics, there are more than 40 kinds of corn virus diseases in the world. Maize dwarf mosaic disease, maize disease and corn streak disease distribution most widely, the most serious harm. In order to solve the problem of corn virus disease prevention and control, Ohio State University has chaired several international maize virus disease prevention research symposiums to exchange and discuss the occurrence and distribution of maize virus disease, pathogen identification, media spread, epidemic law, virus purification , Antisera preparation, resistance identification and prevention and treatment measures to promote the progress of international corn virus disease prevention and control. Before and after 1954 in our country, maize stripe dwarfism occurred in 17 counties in southern Xinjiang, which became a serious problem in the local maize production. In 1963, the black streaked dwarf virus in Shanghai, Zhejiang and Jiangsu Province invaded corn, resulting in a serious decrease of maize , Some people call it corn rough; in 1968, Henan Xinxiang, Anyang summer maize dwarf mosaic disease, causing destructive losses, and gradually spread to Shanxi, Hebei, Shaanxi, Gansu, Shandong and other provinces, as corn Serious disease in 1969; Dunhuang corn streak dwarf disease in Gansu Province in September serious incidence of serious block block crop failure; large area of Hebei Province in 1977, large-scale epidemic of maize; since 1980, Gansu, Shaanxi, Shanxi Province, a large area Corn leaf disease; since 1988, Nanchong, Sichuan Province 9
