Abstract

The conversion of rice-fields to uplands is increased in last 8 years due to the government's policy. To obtain basic informations on plant-parasitic nematodes in converted uplands, we surveyed nematodes associated with crops cultured on the ridge of the rice-fields. The crops mostly cultivated at the ridge of rice-field were soybean (66%), red bean (21%), and perilla (13%). Ten important plant-parasitic nematodes species were identified: Helicotylenchus sp., Heterodera glycines, Meloidogyne arenaria, M. javanica, M. hapla, Paratylenchus projectus, Pratylenchus coffeae, P. neglectus, Rotylenchus incultus, Trichodorus sp. Tylenchorhynchus crassicaudatus, and T. claytoni. Among them, Rotylenchus incultus was the most common plant-parasitic nematode in all three crops. The ridge is a border of rice field, thus plant-parasitic nematodes infested on ridges should be cautioned for future cropping.

정부의 논 타작물 재배사업으로 인하여 밭으로 전환되는 논 면적이 증가하고 있다. 논둑의 식물기생성선충들의 감염 실태를 조사한 결과, 논둑에서 재배되는 작물은 콩 66%, 팥 21%, 들깨 13%였다. 논둑에서 발견된 식물기생성선충은 Helicotylenchus sp., Heterodera glycines, Meloidogyne arenaria, M. javanica, M. hapla, Paratylenchus projectus, Pratylenchus coffeae, P. neglectus, Rotylenchus incultus, Trichodorus sp. Tylenchorhynchus crassicaudatus, T. claytoni 등 총 8속 10종, 미동정 2종으로 국내 주요 식물기생성선충의 속이 거의 모두 포함되어 있었다. 논둑 작물에서 가장 많이 발견된 식물기생성선충은 나선선충류인 Rotylenchus (42%)였다. 처음으로 시도된 논둑 식물기생성선충 조사에서 예상보다 높은 밀도의 주요 식물기생성선충 8속 10종이 발견되었으므로 논둑에서 식물기생성선충이 논이 전환된 밭으로 점염될 염려가 있어 주의가 필요하다.
