Soybean Vein Necrosis Virus
scouted Oct. 2, 2025
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Soybeans in Granville County were being scouted, and it was observed that in 35% of the field there were stunted plants and plants with malformed leaves. There was a suspicion of herbicide injury, and a sample was submitted to the PDIC for diagnosis.
- Conclusion
- Soybean vein necrosis virus (SVNV) was found in the samples from this 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.
