Abstract

This study was conducted to investigate the plant-parasitic nematodes of ornamental foliage plants, citrus orchards, and tea plantations from July to December 2022. As a result of the investigation of plant-parasitic nematodes in 415 foliage plants, root-lesion nematodes were detected most frequently, followed by root-knot nematodes, pin nematodes, and other nematodes. In tea plantations, spiral nematodes, cyst nematodes, and root-knot nematodes were detected. Citrus nematodes, ring nematodes, and root-knot nematodes were discovered in citrus orchards. In foliage plants, tea plantations, and citrus orchards, the detection rate of plant-parasitic nematodes was not high, but root-lesion nematodes were detected. Therefore, it is necessary to apply appropriate control methods to manage root-lesion nematodes during the cultivation of foliage, tea, and citrus plants.

정서적 안정과 휴식에 효과적이며, 공기 정화 등 기능성을 가진 관엽식물에 대한 수요가 증가하고 있으나, 관엽식물에 피해를 유발할 수 있는 식물기생선충에 대한 연구는 전무한 실정이다. 본 연구는 국내 판매되고 있는 관엽식물에서 발생하는 식물기생선충의 검출 여부와 밀도를 파악하고자 관엽식물과 작물재배지에 대해 2022년 7월부터 12월까지 모니터링을 수행하였다. 415개의 관엽식물과 국내 24개 차나무 및 22개 감귤재배지의 식물기생선충을 조사하였다. 관엽식물 내 식물기생선충 조사 결과, 뿌리썩이선충이 가장 많이 검출되었으며, 잎선충, 뿌리혹선충, 침선충이 확인되었다. 차나무재배지에서는 나선선충, 씨스트선충, 뿌리혹선충, 뿌리썩이선충이 검출되었고, 감귤재배지에서는 감귤선충, 주름선충, 뿌리썩이선충, 뿌리혹선충 등이 검출되었다. 관엽식물, 차나무 및 감귤 재배지에서 뿌리썩이선충이 가장 우려되는 식물기생선충이었으나, 뿌리혹선충, 씨스트선충이 일부 검출되어 피해가 우려되므로 온탕침법, 유기농업자재의 사용, 잡초제거 등 식물기생선충의 방제 방법을 재배에 적용하여야 할 것이다.
