Abstract

Twenty-two species of medicinal plants were tested in pots for their host suitability to Meloidogyne hapla under greenhouse conditions. Each plant was inoculated with 5,000 freshly hatched secondstage juveniles. Host suitability was assessed 60 days after inoculation on the basis of root gall index (GI) and reproduction factor (Rf). Twelve species namely, Angelica dahurica, Arctium lappa, Astragalus membranaceous, Carthamus tinctorius, Codonopsis lanceolata, C. pilosula, Coriandran sativum, Glycyrrhiza uralensis, Leonurus sibiricus, Ligusticum tenuissimum, Ostericum koreanum and Peucedanum japonicum were recorded as susceptible to M. hapla with GI, 2.6-5.0 and Rf, 1.3-10.6. Three species, Cassia tora, Coix lachryma-jobi and Perilla frutescens were immune, no gall and nematode found on these plants. Five species, Achyranthes japonica, Atractylodes japonica, Hibiscus manihot, Ricinus communis and Sophora flavescens were considered as resistant with Rf value of 0.3-0.6. Aster scaber and Agastache rugosa were tolerant and hypersensitive, respectively.
