According to the Plant Prevention Act, there are 35 weeds that are managed to prevent them from entering Korea. When these were classified by family, 12 species (34%) of the Asteraceae, 4 species (14%) of the Poaceae, the Amaranthaceae, and the Apiaceae were followed. When classified by life cycle, annuals accounted for 19 species (54%), while perennials had 12 species (34%), which showed a high percentage of annual weeds. Propagation was maintained by various methods such as seeds and rhizomes. In terms of origin, 8 species (23%) were from North America and 6 species (17%) were from the Mediterranean coast. Although 10 years have passed since the first designation of managed weeds according to the Plant Quarantine Act, many weeds are still called by scientific names, which can decrease the work efficiency of plant quarantine officers. It would be better to give them a Korean name that is easy to call. It is also hoped that the addition and deletion of managed weeds will be made flexibly to increase the efficiency of border quarantine.
