Soybean Vein Necrosis Virus Spreads Across U.S. Soybeans
Keep your eye on a new viral soybean disease called soybean vein necrosis virus (SVNV). So far, little is known about this disease that first surfaced in Tennessee in 2008. Still, it behooves you to watch for it this year.
Since its 2008 debut, SVNV has spread through a widespread geographic area that includes northern Indiana, Ontario, Iowa, Wisconsin, Minnesota, and Illinois. The virus belongs to the genus Tospovirus, a group of plant viruses normally transmitted by thrips instead of by seed or mechanical means. Because SVNV was so recently found in soybeans, virologists suspect it may have been recently introduced from another host.
