Abstract

The incidence of virus disease on peppers was investigated at the 52 areas in the whole country in 2002, 2004 to 2006. Among the six viruses, Cucumber mosaic virus (CMV), Pepper mottle virus (PepMoV), Pepper mild mottle virus (PMMoV), Broad bean wilt virus 2 (BBWV2), Tobacco mild green mosaic virus (TMGMV) and Tomato spotted wilt virus (TSWV), infecting peppers in Korea, the incidence of CMV, PepMoV, PMMoV and BBWV2 was 29.4%, 13.6%, 14.3%, 25.6%, orderly. TMGMV and TSWV had the same low infection rate of 1.0%. The infection rate of CMV was higher as 53.3% and 34.2% in 2002 and 2004, but it was decreased to 18.2% and 11.9% in 2005 and 2006, respectively. The infection rate of BBWV2 was lower as 1.3% in 2002 and 1.8% in 2004, but it was increased abruptly to 41.3% in 2005 and 58.2% in 2006. For the types of mixed infections of pepper viruses, the incidence of CMV+PepMoV was 62.6% in 2002 and 50.0% in 2004, and that of CMV+BBWV2 was increased suddenly from 33.3% in 2005 to 83.2% in 2006. The triplex infection of CMV+BBWV2+PepMoV was 6.4% in average. CMV caused severe mosaic and BBWV2 induced ring spots, and the two mixed virions caused chlorosis on the leaves of red peppers. TSWV induced the typical symptoms of multiple ring spots on the leaves and fruits of red peppers.
