Soybean Vein Necrosis Virus
scouted Aug. 20, 2025
- Background
- Soybeans in Franklin County were scouted, and it was observed that plants were starting to show signs of reddening and browning. 5% of the field is affected, and it's in a low area of the field. A sample was submitted to the PDIC for diagnosis.
- Conclusion
- Soybean vein necrosis virus (SVNV) was also present in the field. SVNV is a Tospovirus occasionally present in North Carolina soybeans that, while not economically important in the region, has the potential to cause severe damage in individual soybean fields. This virus infects the whole plant and leads to necrotic tissue. It's a vector-mediated pathogen spread by immature thrips, and currently, there is no economical management tool for SVNV.
