St. Augustinegrass plants with viruslike symptoms were observed in a few lawns in central Arkansas in 1981. Assays of affected plants by mechanical inoculation of indicator plants and serologic tests confirmed that the plants were infected with the St. Augustinegrass decline strain of Panicum mosaic virus. This is the first report of this disease in Arkansas.
