Soybean vein necrosis virus
scouted July 25, 2023
- Scientific Name
- Soybean vein necrosis orthotospovirus
- Background
- Soybeans in Granville, variety Hutchinson, were scouted and observed 20% of field was affected by browning and yellowing, in a mottled pattern, leaf spot, stunting, widespread, and insect signs like boring and scars. The sample came from a second year of soybeans from an organic farmer with heavy deer and weed pressure.
- 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.
