Interpretive Summary:

Technical Abstract: This week our laboratory confirmed the presence of Soybean vein necrosis-associated virus (SVNaV) in soybeans sampled in Wisconsin. Samples were taken at several times during September and processed in our laboratory. Symptoms of the disease caused by the virus include yellowing (chlorosis) of the leaf veins, yellowing of the leaves, and browning (necrosis) of the leaf veins and leaves. The first report of the virus in soybean in the USA was from symptomatic plants in Tennessee in 2008. Since this discovery in 2008, SVNaV has been confirmed in other states, including Kentucky, Arkansas, Missouri and most recently Wisconsin.
