Soybean vein necrosis virus
scouted Aug. 25, 2023
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Edamame soybeans in Lenoir county, variety Asgrow AG54XFO, were scouted and observed 5% of field affected by yellowing, and leaf spots, in random parts of the field. Spotting was noticed in the mid/upper canopy. They soybeans were in the early pod stage. The site is dry and sunny.
- 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.
