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.
