Soybean vein necrosis virus
scouted Sept. 19, 2023
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Soybeans in Randolph County were scouted, and 5% of the field was observed to be affected by widespread leaf spots. The site location is sunny and is being used for an OFT trial.
- 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 pathiogen spread by immature thrips and currently there is no economical management tool for SVNV.
