The Agriculture, Food and Rural Affairs Quarantine Headquarters in South Korea has announced plans to strengthen export quarantine after the discovery of the pest 'tomato horn moth' in some domestic farms. The pest, originally introduced from foreign countries, causes damage to tomato plants by making burrows in the leaves or boring holes in the fruits and stems. The Quarantine Headquarters has already strengthened surveillance and supported pest control in affected farms. A meeting with Japanese plant quarantine experts was held to discuss export management requirements without suspending exports. Approximately 3,400 tons of tomatoes and cherry tomatoes are exported to Japan by domestic farmers every year, which accounts for 1.2% of domestic production.
