SCN is important because:
- SCN is widespread in soybean production areas of Virginia.
- In a typical year, SCN causes more yield loss in soybean than any other disease.
- SCN in fields increases the incidence and severity of several soil-borne diseases.
- Shorter rotations out of soybean have led to increased populations of SCN and other nematodes.
- Limited use and availability of nematicides have led to increased populations of SCN and other nematodes.
- SCN populations in Virginia have overcome major sources of genetic resistance in soybean varieties.
