美国堪萨斯州的土传花叶病毒病(WSBM)是冬小麦的一种严重病害.该病原病毒被认为是通过土壤真菌—禾谷多粘菌(Polymyxagraminis Led.)传播的.该病自1952年开始在堪萨斯州流行以来,已蔓延到占该州三分之二面积的东部地区,而西部三分之一地区却极少发生.在过去的7年中估计该州因此病平均每年减产小麦3.37亿公斤.
Soil-borne mosaic virus disease (WSBM) in Kansas is a serious disease of winter wheat that is thought to have been transmitted through the soil fungus Polymyxagraminis Led. Since 1952 Has spread to two-thirds of the eastern part of the state since it became popular in Kansas, while one-third of the western part of the country rarely occurs, and in the past seven years it has been estimated that the state has thus managed to cut an average of 337 million annually kg.
