What are the technical measures for soybean pest and disease control
Soybean cyst nematode disease, commonly known as "fire dragon seedling," is a soil-borne, devastating soybean disease. The western part of our province is a severely affected area of this disease. In mild cases, yield is reduced by about 10%; in severe years, yield can be reduced by 30%-50%, and in serious cases, there may even be total crop failure. Soybean cyst nematode mainly damages soybean roots. Affected plants are stunted and poorly developed, and at the seedling stage are susceptible...
