Viral infections in soybean can affect the health and quality of the seed in a number of ways, but especially when they are transmitted to the plant’s progeny. Alfalfa mosaic virus, Soybean mosaic virus, Tobacco streak virus, and Tobacco ringspot virus are viruses that infect soybean and transmitted by seed. Soybean vein necrosis is an emerging virus that causes soybean vein necrosis.
The study objectives are:
- Survey of variety trials in Wisconsin to assess the occurrence of soybean vein necrosis virus and tobacco streak virus infections.
- Monitor populations of thrips that transmit sobean vein necrosis virus, using sentinel crops to determine the timing of arrival of viruliferous thrips.
