Phytoparasitic Nematodes Associated with Different Cultivars of Grape Grown in Two Type of Soil in Egypt.
Journal Title: Egyptian Journal of Agronematology - Year 2017, Vol 16, Issue 2
Abstract
Survey was conducted in Giza, qualiabia and Behaira governorates of Egypt during 2010-2011 seasons, to study the occurrence and population density phytoparasitic nematodes associated with grapes (Vitis). A total number of 160 soil and root samples were collected from the rhizospher of six grape cultivars Bez-Alanza, Flame seedless, King Ruby, Romy Red, Superior and Thomoson seedless were collected by digging soils to a depth of 32-40 cm with stainless steel half –tubes. The results indicated that the present of ten phytonematode genera, Criconemoides, Ditylenchus, Helicotylenchus, Hoplolaimus, Meloidogyne, Pratylenchus, Rotylenchulus, Tylenchorhynchus, Tylenchulus and Xiphinema. Frequency and population density of each nematode genera different according to grape cultivars and soil type. The root knot nematode (Meloidogyne) was prevalent nematode in all cultivars and localities it was present in 77.32% of total samples. Also root knot nematode (Meloidogyne) was frequent in (F.O=72.5%) than in clay soil (16.77%),while the citrus nematode (Tylenchulus) was more frequent in clay soil (66.71) than in sandy soil (0.67%).
