Soybean mosaic virus spreads through seeds. The first virus in the field came from the seed with the virus, and the diseased seed grew into a diseased seedling. The virus of the diseased seedlings spreads and spreads through winged grasshoppers in the field. According to the epidemic characteristics of soybean mosaic virus, the focus of prevention and control:
(1) Selection of disease-resistant varieties: There are significant differences in the resistance of soybean varieties to soybean mosaic virus. Selection of disease-resistant varieties is the most cost-effective way to prevent and treat this disease.
(2) Remove diseased seedlings in the field in a timely manner, in particular, leave diseased plants in the fields, reduce the amount of field diseases, and reduce the seed virus rate.
(3) Remove weeds from the fields and land and eradicate the breeding and breeding sites of locusts.
(4) Chemical agents kill aphids in soybean fields, cut off the spread of the virus, and control spread and spread.
