Cyst nematodes are among the major plant-parasitic worldwide, and they cause significant damage to Brassicaceae crops, including Kimchi-cabbage, in Korea. To survey incidence of cyst Kimchi-cabbage fields, 469 soil samples were collected from main producing areas between 2018 2021. Only belonging genus <i>Heterodera</i> investigated, overall nematode was found be 40%. Regionally, highest observed Taebaek, reaching 89%, with mean densities cysts eggs per 500 cm³ recorded at 522 49,734, respectively. Based on Bayesian analysis mitochondrial DNA cytochrome c oxidase subunit I gene sequence, identified as four species: clover (<i>Heterodera</i> trifolii, HT, frequency: 78%), soybean (<i>H. glycines</i>, HG, 11%), sugar beet schachtii</i>, 4%), white sojae</i>, HSo, 2%). Mixed infestations some HT + HG (4%) HSo (1%). These results indicate that is dominant species In conclusion, implementing effective management strategies critical minimize economic losses production
