  • During routine surveys for pest and pathogen incidences at a golf course in 2007, circular to irregular patches of stunted, chlorotic and wilted turfgrass var. Pencross were noticed in Jinhae, Gyeongnam province, Korea. Soil samples collected from those diseased patches of the golf course yielded high population (average 126 nematodes/$100\;cm^3$) of a stunt nematode, Tylenchorhynchus claytoni, which is described and illustrated in this paper with light and scanning electron micrographs. This is the first report on the occurrence of T. claytoni in turfgrass in Korea.

  • A taxonomical revision of the Korean species of family Belonolaimidae has been undertaken. Twenty three species belonging to four different genera under two subfamily were reported from Korea hiteroto. Among them Tylenchorhynchus martini to T. annulatus. Merlinius acuminatus, M. brevidens, M. joctus, M. lenorus, M. nothus and M. koreanus to genus Geocenamus. M. clavicaudatus, M. macrurus, M. socialis to genus Amplimerlinius and Quinisulcius capitatus to Tylenchorhynchus capitatus were synonymized respectively. The keys of the each genera were proposed for identification. Distribution, host plants and photograps were included.

  • To investigate the incidence of plant-parasitic nematodes (PPNs) in perilla fields in Korea, 55 soil samples were collected from open fields and plastic-film house fields and were analyzed during January 2020 to October 2020. Root-lesion nematodes (RLNs), spiral nematodes, root-knot nematodes, and stunt nematodes were detected in perilla fields, and the incidences of RLNs (39%) and spiral nematodes (55%) were higher than those of other nematodes. Among PPNs, RLNs are very important species found on economic crops. The detection frequency of RLNs was increased due to continuous crop cultivation, and the frequency of fields that cultivated only one crop continuously for over 11 years was twice higher than the frequency of fields that cultivated only one crop for less than 5 years. The PPN species diversity and density were different between leaf-perilla cultivation fields and seed-perilla cultivation fields. In phylogenetic analysis of RLNs, Pratylenchus penetrans, P. vulnus, and Pratylenchoides leiocauda were identified in perilla fields. These results suggest the RLNs should be considered for establishing nematode management strategies in perilla fields in Korea.
