Soybean Vein Necrosis Virus
Pest Background
- Soybean Vein Necrosis Virus is an Orthotospovirus.
- This virus can be seed borne or vectored by multiple thrips species.
- Increased damage is observed in late planted soybeans.
Identification
- As the name implies, symptoms will follow leaf veins starting as yellowing (chlorosis) (Fig 1).
- Yellowing will develop into red-brown lesions (Fig 2).
- On the underside of the leaf, browning of the veins may be observed (Fig 3).
Management
- Insecticide applications to control vectors are not successful since complete insect removal is not possible.
- Use certified, disease-free seed to limit chance of seed transmission.
- SVNB is not thought to impact yield but may reduce oil concentration and lower seed quality.
