Project Summary

Recently, a group of scientists from the University of Arkansas, Mississippi State University, and Louisiana State University characterized a new disease of soybeans prevalent in our three states, taproot decline (TRD). The regional distribution of disease occurrence and yield loss is unclear at this time. However, it has been found as far north as Craighead County, and some farmer and consultant reports indicate losses could be as high as 10 bu/A in fields. In 2016, fields in Mississippi and Louisiana suffered substantial yield losses from this disease. Currently, we do not have seed treatment fungicide or varietal recommendations for growers to combat TRD. Understanding the regional distribution, commercially available seed treatment efficacy, and varietal susceptibilities are necessary for successful management of this disease in Arkansas.
