SVNV
scouted Aug. 24, 2026
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- A soybean field in Franklin County was being scouted, and it was observed that 10% of the field was affected by browning and yellowing in random areas of the field. There is suspicion of guava root-knot nematode. 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.
