Soybean vein necrosis virus
scouted Aug. 22, 2023
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Soybeans in Rowan county were scouted and observed 50% of the field affected by leaf spots, in random areas. New growth on the plants were curled shriveled. The older leaves seem unharmed. Some leaf spots were noticed. The pods don't seem to be bothered.
- 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.
