Soybean vein necrosis virus
scouted Aug. 16, 2022
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Soybeans in Pasquotank county, variety AgVenture 46V6X, were scouted and observed 2% of the field was affected by reddening and yellowing, and stunting. The site is localized and dry. Areas of disease start at the edges of the field and in some cases go out into the field. Plants are stunted and light green and in some cases reddish yellow in color. Affected leaves have dark veins. Also, some black lesions on stems like might be seen with kudzu bug feeding.
- 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.
