Soybean vein necrosis virus
scouted July 24, 2024
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Soybeans in Rowan County were scouted and observed 40% of the field is affected by browning and reddening.
- 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.
