국내 딸기 시설재배 주산단지 토양 내의 주요 식물기생선충 감염 현황

To investigate the incidence of plant-parasitic nematodes from plastic-house fields of strawberry, 170 soil samples were collected from the main producing area of strawberry in Korea from 2014 to 2015. Based on the investigation, root-lesion nematode (RLN; Pratylenchus spp.) and root-knot nematode (...

Summary:To investigate the incidence of plant-parasitic nematodes from plastic-house fields of strawberry, 170 soil samples were collected from the main producing area of strawberry in Korea from 2014 to 2015. Based on the investigation, root-lesion nematode (RLN; Pratylenchus spp.) and root-knot nematode (RKN; Meloidogyne spp.) are the most important pests in plastic-house fields of strawberry with 57% and 36% incidences, respectively. Among the collected fields, 96 and 63 fields were infected RNL and RKN, respectively with 44 fields (38.8%) being detected at both nematode. High degree of incidence of both nematodes were observed in the regions of Jinju, Gyeonnam Province, Korea. For identification of species level, phylogenetic and distance analysis were performed using RLN and RKN isolates generated from the regions of Jinju. The results indicated that the RLN and RKN isolates were Pratylenchus vulnus and Meloidogyne hapla, respectively. This study showed that P. vulnus and M. hapla could be most dominant species in plastic-house fields of strawberry. This data will provide basic knowledge for development of effective control strategies. 국내 딸기 주산단지의 시설재배지 170개 포장으로부터 토양시료를 채취하여 식물기생선충을 조사한 결과, 농업적으로 중요한 뿌리썩이선충이 96개포장(56.5%), 뿌리혹선충이 63개 포장(37.1%)에서 검출되었다. 이 중 44개 포장은 뿌리썩이선충과 뿌리혹선충이 복합감염된 것으로 나타났다. 뿌리썩이선충과 뿌리혹선충의 도별 발생은 경남지역이 각각 68%와 46%, 시 군별로는 진주시가 81%와 54%로 가장 높았다. 국내 최대의 딸기 수출재배단지이자 식물기생선충의 검출률이 가장 높았던 진주시의 뿌리썩이선충과 뿌리혹선충의 종 동정 결과, 사과뿌리썩이선충(P. vulnus), 당근뿌리혹선충(M. hapla)이 우점하고 있는 것으로 나타났다.
