小麦黄花叶病是近年我省罗田、英山、应山等县小麦产区发生的一种新病害。此病对小麦能造成一定危害,个别田块甚至酿成绝产,并且发病面积有逐年扩大的趋势,如罗田县1979年为2,000亩,1982年扩大到17,000亩,占小麦面积的8.6％;危害程度亦逐年加重。针对生产上存在的这一问题,我们于1982—1983年对此病的病原进行了传播试验和分离鉴定。 Wheat yellow mosaic disease is in recent years in our province Luotian, Ying Shan, Ying Shan County wheat occurred in a new disease. The disease can cause some harm to wheat, and even led to some individual plots of crop failure, and the area of ​​incidence has been expanding year by year trend, such as Luotian County in 1979 was 2,000 acres in 1982 expanded to 17,000 acres, accounting for 8.6% of wheat area, ; The degree of harm also increased year by year. In response to this problem of production, we conducted the transmission test and isolation and identification of the pathogen of the disease in 1982-1983.
