Soybean vein necrosis virus
scouted Aug. 11, 2023
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Soybeans in Montgomery county, variety AG54XF0, were scouted and observed 75% of field was affected by dieback, browning and yellowing, in a mottle pattern. Leaves and stems were affected. The site is dry.
- Conclusion
- The issue identified was Soybean vein necrosis virus (SVNV) 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.
