Grape plants (Vitis vinifera L.), like other major horticultural crops, suffer from attacks by plant pathogenic nematodes. These parasites are a serious burden for viticulturists all over the world and lead to reduced vine vigour crop yield. The nematode infesting grapevines include Meloidogyne spp., Pratylenchus Criconemella Tylenchulus Helicotylenchus Heterodera spp. etc. Besides these genera...

American boxwood, Buxus sempervirens var. globosum, was tolerant of Helicotylenchus dihystera [in field microplots] as measures of plant growth were similar to the control and nematode densities were maintained at high levels (1,705-1,810/500 cm(3) soil after 29 months). Boxwood was intolerant of Pratylenchus vulnus at initial densities of 163, 281, or 475 nematodes per 500 cm(3) soil. In compa...

Bitki paraziti nematodlar kültür bitkilerinde ekonomik kayıplara neden olan zararlı organizmalardır. Bu çalışma Kırgızistan’ın kuzeyinde yer alan Talas ve Tokmok Bölgeleri patates ekiliş alanlarında bulunan bitki nematod türlerini saptamak amacıyla yürütülmüştür. amaçla 2016 yılı yaz aylarında yapılan survey çalışmalarında alanlarından 15 adet toprak örneği alınmıştır. Örneklerden elde edilen t...

Abstract Plant-parasitic nematodes (PPNs) can cause substantial economic yield losses to many agronomic crops in the United States. A regional-scale survey was completed across 20 counties determine PPNs prevalence Michigan corn and how factors such as soil type, tillage, irrigation, cropping systems influence their distribution. Ten different major genera of were identified fields: Longidorus ...

The interception of Ditylenchus dipsaci, D. destructor, and Aphelenchoides fragariae, which are classified as quarantine pests, has been reported to occur on imported garlic bulbs used for consumption at several traditional markets in Bogor. This finding should increase awareness the chance contamination Indonesia’s fields. study aimed evaluate nematode community determine polyphasic characters...

Double-stranded RNA (dsRNA) molecules targeting two genes have been identified that suppress economically important parasitic nematode species of banana. Proteasomal alpha subunit 4 (pas-4) and Actin-4 (act-4) were identified from a survey of sequence databases and cloned sequences for genes conserved across four pests of banana, Radopholus similis, Pratylenchus coffeae, Meloidogyne incognita a...

Treated and nontreated field plots were assayed, and the population density of each plant-parasitic nematode present was compared with crop growth and yield and with the population densities of other nematode species in the same plots. The strongest correlations between nematode population densities and growth responses occurred when soil assays for nematodes were made 55-73 days after planting...

Combinations of winter and fall cover crops were evalu­ ated for the management of plant-parasitic nematodes. The winter cover crops examined were rye (Secale cereale) and narrow-leafed lupin (Lupinus angustifolius) and the fall cover crops were soybean (Glycine max), cowpea (Vigna unguiculata), sorghum-sudangrass (Sor­ ghum bicolor x S. sudanense), sun hemp (Crotalaria juncea), and corn (Zea m...
