Heterodera trifolii, mostly known as clover cyst nematode, is currently a serious problem for Chinese cabbage growers of the highland area in Korea. Due to lack of readily information about the nematode on Chinese cabbage in Korea, the pest steadily spread within the highland areas and has become a serious setback. Occurrence, spatial aggregation, egg hatching and the pathogenicity of this nematode are depicted in this study from ecological point of view. The study results suggest site-specific control and a potential planting time for the cabbage to avoid severe damage caused by this nematode.
