AbstractPark, S. D., Z. Khan, and Y. H. Kim. 2007. Evaluation of medicinal herbs for resistance to root-knot nematode, Meloidogyne incognita, in Korea. Nematropica 37:73-77. Thirty-two species of medicinal herbs were tested in pots for their host suitability to Meloidogyne incognita under greenhouse conditions. Each plant was inoculated with 5000 eggs + second-stage juveniles. Host suitability was assessed 60-days post-inoculation on the basis of root gall index (GI) and reproduction factor (RF). Eighteen species, Angelica acutiloba, A. gigas, A. tenuissima, Astragalus sinicus, Dolichos lalab, Dystaenia takesimana, Foeniculum vulgare, Glehnia littoralis, Hepatica asiatica, Lonicera japonica, Mentha canadensis, Osmunda japonica, Paeonia albiflora, P. mountan, P. suffruticosa, Potentilla discolor, Rehmannia glutinosa and Saururus chinensis were recorded as susceptible to M. incognita with a GI of 2.7-5.0 and RF values between 1.5 and 13.1. Nine species, Achyranthes bidentata, Acorus graminens, Adenophora triphylla, A. remotiflora, Atractylodes chinensis, Dicentra spectabilis, Hibiscus mutabilis, Pulsatilla koreana, Rubus coreanus were considered as resistant with RF values of 0.3-0.8. Five species, Allium tuberosum, Artemisia capillaris, Chrysanthemum frutescens, C. zawadskii and Rubia akane were non-host with no galls or nematodes found on the roots.
