Sowbane mosaic virus（SoMV）is one of the most important diseases for spinach．SoMV can be
transmitted by seed，pollen，insect vector and mechanical manners．Along with the further expantion in imported
quantities of seeds and seedlings，and planting industrialization，the risk of SoMV introducing into China is
increasing．This paper reviewed the biological characteristics，distribution，host range，endanger sympton，
transmission route，and detecting techniques of SoMV．The paper also summarized the potential danger and risk
of SoMV coming into China．
