1978-1980年,山西北部麦类病毒病(大麦黄矮病毒BYDV)严重流行,200万亩小麦和300万亩莜麦遭受损失,每年减产3亿多斤。为了尽快控制麦类病毒病的流行,找出确实可行的防治措施,协作组于1980年开始了防治试验和研究,1980-1982年在全省范围内进行了4次传毒介体-麦蚜的越冬场所和流行规律的考察,不但肯定了我省北部春麦区的传毒介体是迁飞性蚜虫,而且基本查清了全省麦蚜的越冬场所和分布规律,在此基础上,提出了病害防治策略。
From 1978 to 1980, the wheat virus disease (BYDV of barley yellow dwarf virus) in northern Shanxi was extremely prevalent, causing losses to 200 million mu of wheat and 3 million mu of oatmeal, yielding more than 300 million kilos per year. In order to control the epidemic of wheat virus as soon as possible and find out the feasible control measures, the collaborative group started the prevention and control experiment and research in 1980. Four poison mediators were used throughout the province from 1980 to 1982 - wheat aphid The overwintering sites and the investigation of the epidemic laws not only affirmed that the mediator of infection in the spring wheat area in the northern part of our province is a migratory aphid, but also found out the overwintering places and distribution rules of wheat aphids in the whole province. On this basis, Disease prevention and control strategy.
