Disease Note. First Report of Peanut Mottle Virus and Clover Yellow Vein Virus on Alyceclover in Georgia. J. D. Miller, USDA-ARS, Georgia Experiment Station, Experiment 30212. J. W. Demski, D. D. Baltensperger, and H. D. Wells. Georgia Experiment Station, Experiment 30212, University of Florida, Gainesville 32611, and USDA-ARS, Coastal Plain Experiment Station, Tifton, GA 31793-0748. Plant Dis. 71:192. Accepted for publication 11 November 1986. Copyright 1987 The American Phytopathological Society. DOI: 10.1094/PD-71-0192B. Viruslike symptoms were noted on naturally infected leaves of seven Florida strains of alyceclover (Alysicarpus vaginalis (L.) DC.) in a replicated performance test at Tifton, Georgia, in October 1985. One to three symptomatic plants of each strain were sampled in one replication, with additional replications sampled for two strains. Enzyme-linked immunosorbent assays (I) were done on these 14 samples. Peanut mottle virus (PMV) was detected in eight samples and clover yellow vein virus (CYVV) in nine; four samples were infected with both PMV and CYVV. Cucumber mosaic virus and bean yellow mosaic virus (BYMV) were not detected. Mechanical inoculation of alyceclover with PMV and CYVV resulted in symptoms, but inoculation with BYMV did not. Peanut stripe virus and its symptom variant peanut blotch virus, not found in field samples, also infected alyceclover by mechanical transmission. The potential effect of these viruses on alyceclover requires further study. |
