Soybean vein necrosis virus (SVNV)
This virus is found in North America and infects soybean plants. Other legumes may also become infected. The disease was first discovered in southern parts of the U.S. in 2008. It has since spread to other soybean growing parts of North America, including eastern Canada, and has become very common. The virus affects the seed quality but apparently not the yield of soybeans (Anderson et al., 2017).
Initial symptoms include the formation of necrotic spots along major veins of the upper and lower leaf surfaces. These expand and merge to larger necrotic blotches and finally give the leaves a scorched appearance. The virus can be transmitted by several thrips species (Keough et al., 2016) and also through seeds (Groves et al., 2016).
