Among the plant specimens requested from agricultural actual places of farmers, Agency of agricultural extension services and so forth for the diagnosis of plant virus diseases in 2009, the rate of crop types was 87.5% for vegetables, 4.0% for upland crops and 3.5% for orchids. In vegetables, the crops damaged severely by viral diseases were red pepper and tomato by the infection rate of 51.6% and 26.5%, orderly. Virus species occurring vegetables were 19 and the economically important viruses were Cucumber mosaic virus (CMV), Tomato spotted wilt virus (TSWV), Tomato yellow leaf curl virus (TYLCV), Pepper mild mottle virus (PMMoV) with the infection rate of 33.2%, 16.9%, 16.1% and 7.4%, respectively.

TYLCV was spread at 34 areas of Si and/or Gun, 22 areas in 2009 and 12 in 2008. Distribution of TSWV was expanded newly in 6 areas of Si and/or Gun including Gangryung, Gangwondo in 2009, and its occurrence areas were 23 Si and/or Gun after first incidence at Anyang area in 2004.
