Abstract
Red clover of different ages in Centre, Crawford, Lancaster, Westmoreland and Wyoming counties was surveyed for viruses in 1979; Centre and Lancaster counties were surveyed again in 1980. Enzyme-linked immunosorbent assay was used to detect specific viruses in randomly selected and symptomatic plants. Results for the 2 survey yr were similar. Bean yellow mosaic virus, the most common in all fields, produced > 80% of all positive assays in both years. Alfalfa mosaic, red clover vein mosaic, clover yellow vein, and peanut stunt viruses were detected at much lower frequencies. Clover yellow mosaic virus was not detected. Incidence of viral disease increased rapidly from year of seeding to the following year; it then stabilized at levels ranging 30-54% of the plants infected, even in stands seeded 4 yr earlier.
