The following is in the Kentucky Pest News from Don Hershman

Over the past few weeks, we have been getting questions about fields that look similar to Fig. 1. Initially, we thought the problem was related to nitrogen deficiency in areas of fields that were subject to water saturation. In some cases, inadequate availability and/or uptake of nitrogen may be the culprit. However, we have since determined that most of the fields exhibiting patches of stunted and yellowed plants are most likely affected by Wheat Soil-borne Mosaic Virus (WSBMV). We have come to this conclusion based on samples from symptomatic fields that have tested positive for WSBMV using a very reliable antibody-based diagnostic test known as ELISA.
