Latent Virus in Peanut in Georgia Identified as Cowpea Chlorotic Mottle Virus. C. W. Kuhn, Division of Plant Pathology, University of Georgia, Athens 30602. J. W. Demski.

Since 1976,cowpea chlorotic mottle virus (CCMV) has been isolated at least I0 times from peanut plants (Arachis hypogaea L.) grown in commercial fields and experimental plots in Georgia. Virus identification was based on serological tests and symptomatology on several known hosts (1). From different locations in Georgia, the type and mild strains of CCMV were isolated from symptomless peanut plants or those with mottle or stripe symptoms caused by other peanut viruses (2). Mechanical inoculation did not cause symptoms on I3 peanut cultivars, although infection in each was confirmed serologically. Despite lack of foliar symptoms, CCMV occurs in relatively high concentration in infected peanut tissue and has significant disease potential when in mixed infections with other viruses. Presence of the virus should be recognized.
