New hosts [broad bean (Vicia faba L.)] and record of root-knot nematode in Turkey

Abstract :

Plant-parasitic nematodes (PPNs), particularly Meloidogyne spp. root-knot nematodes (RKNs), are widely distributed and cause significant yield losses in a wide range of crops. Major root-knot nematode species: M. arenaria, M. exigua, M. graminicola, M. hapla, M. incognita, M. javanica, M. mayaguensis. PPNs, host association and distribution in different localities of Turkey have been surveyed. A total number of 240 nematode species of PPNs belonging to 56 genera of Tylenchida detected in Turkey. These nematode species found associated with 66 plants from 48 different localities of the country. In Turkey, the species M. incognita, M. arenaria, M. javanica and M. hapla are the most commonly found, with M. incognita and M. javanica which causes serious problems to a number of economically important agriculture and greenhouse crops. During a survey of PPNs, moderate to severe root-knot infection was observed on the roots of broad bean (Vicia faba L.) growing in the vegetable and legumes production in Niksar district, Yolkonak village (Tokat, Turkey). After examination of the root galls, mature females were found attached in abundance on the roots. On the basis of perennial pattern of mature females of Meloidogyne javanica (Treub) were identified. Broad bean (Vicia faba L.) (Fabaceae) appeared to be a new hosts of the RKNs in Turkey not previously reported. In Turkey, Meloidogyne javanica was found for the first time in Iğdır on unknown host and is presently widespread in various Turkish regions, where it causes severe damages. It is extremely polyphagous, attacks severely plants but is very damaging also to Vitis vinifera, vegetables, Cucurbitaceae, ornamental plant, Musa sp., Arachis hypogaea, Lycopersicum esculentum and Capsicum annuum.
