Dr. Ron Heiniger identified Soilborne Wheat Mosaic Virus in Beaufort County on April 1st. Dr. Angela Post has seen many cases of this as she has traveled around the state recently, some more severe than what we are seeing in these photos.

The disease is probably found throughout these fields. However, these symptoms are showing up in compacted areas which receive repeated traffic throughout the season. Plants in these areas have limited rooting depth, which places a greater stress on the plants. This stress seems to enhance the symptoms of the virus (stunted growth, yellowing of infected plants), resulting in the “streaky” appearance of the fields.
