Starting January 2023, Korean farmers exporting fresh tomatoes and seedlings to Japan must adopt net cultivation and verify for tomato hornworm infection, as per new quarantine guidelines announced by the National Institute of Animal Quarantine. This step is taken to manage the risk of the alien quarantine pest, following its detection in Korea. The guidelines mandate registration of cultivation and sorting facilities, installation of fine-mesh nets, and confirmation of no tomato hornworm infection through trap inspections, before the final export quarantine and issuance of an export quarantine certificate.
