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.
