Soybean vein necrosis virus
scouted Aug. 19, 2022
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Soybeans in Wilson county, variety DG48xt90s, were scouted and observed 5% of the field was affected by defoliation, leaf spot, mold/mycelium, root rot, and stem rot randomly throughout. These soybeans are 4.8 maturity, close to senescence. Plant stems, crown and root are affected
- 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.
