호남지역 시설재배지 박과작물에서 뿌리혹선충 발생분포

Five species of cucurbits from major cultivation areas in Jeollanam-do and Jeollabuk-do have been investigated from May to October 2013 in order to create D/B on the occurrence and distribution of Meloidogyne spp. occurring in greenhouse-grown crops according to region·crop, and in order to utilize it as data for pest control, such as the selection of cultivar resistant to Meloidogyne spp., and rotation crop. According to the results of investigation, 50% of cucumber, 31.3% of melon, 26.7% of watermelon, 30% of squash and 18.2% of melon were infected. In cucumber, there was the most severe damage of Meloidogyne spp. in Gimje region, Jeollabuk-do, and the larval density was an average of 1,999 per 100㎝³ soil unit. According to the results of species identification using PCR, the investigation showed that 2 species of Meloidogyne spp. were identified, and they were arranged in the following order of larval density: M. incognita> M. arenaria.
