An extensive field survey of plant-parasitic nematodes associated with most of field and vegetable crops and fruit trees was conducted in most of the irrigated and rainfed agricultural areas of Karak Province of Jordan during 2007-2009. Several species of plant-parasitic nematodes were recorded. The most important species were root-knot nematodes (Meloidogyne javanica and M. incognita), root-lesion nematodes (Pratylenchus spp.), spiral nematodes (Helicotylenchus spp.), Citrus nematode (Tylenchulus semipenetrans) and stunt nematodes (Tylenchorhynchus spp.). Some nematode species (Paratylenchus projectus, Pratylenchus brachyurus, Tylenchorhynchus hordei and Leptonchus granulosis) were recorded for the first time in Jordan and some of the surveyed areas were recorded as new sites for most nematode species e.g. Wadi bani Hammad region for root-knot nematodes on tomato and Al-Mujib Valley for Citrus nematode on both olive and Citrus trees.
