SCN is important in Ohio because:
- SCN contributes to soybean yield loss in Ohio every year.
- Low yielding fields may have high SCN numbers with no above ground plant symptoms.
- SCN infestations now occur statewide and can be detected in most fields in the state.
- Some fields with high populations have adapted to the most common source of resistance (PI88788).
- SCN distribution – Ohio.
- SCN distribution – Nationwide.
SCN Management Recommendations
There are multiple tactics for managing SCN:
- Identify fields with SCN + monitor populations.
- Rotate crops.
- Use resistant varieties wisely.
- Use best cultural practices.
- Manage other diseases (SDS, BSR).
- Prevent introduction.
