Soybean vein necrosis is beginning to show up in some soybean fields in the region. Soybean vein necrosis, caused by a thrips vectored virus, begins as diffuse yellow blotchy leaf spots, often around the veins. As lesions develop, an amber/brown color shows up. Veins and tissue around the veins turn dark over time as lesions spread. Little is known regarding yield loss from this disease.
