The two most economically important plant-parasitic nematodes infesting cotton (Gossypium hirsutum) in the United States are the root-knot (Meloidogyne incognita) and the reniform (Rotylenchulus reniformis) nematode. The common means of managing these pests is use of in-furrow or seed-treatment nematicides, or by rotation with non-host crops or resistant cultivars of crops grown in rotation. Un...

Root-knot nematode penetration and morphopathlogy of the infection sites were studied in roots, stem and hypocotyls of Luffa cylindrica, L. and effect of combined inoculation of Vesicular Arbuscular Mycorrhizae (VAM) fungi included Glomus mossae, Glomus intraradices, G. fasciculatum, Acaulospora sp. and Meloidogyne incognita (Root-knot Nematode) were investigated. The maximum number and size of...

Interactions between root-knot nematodes and viruses were recently reviewed by Taylor (4). Compared to virus-free cowpea (vigna sinensis Endl.), cowpea mosaic virus-infected plants formed fewer galls on roots in response to infection by Meloidogyne incognita (Kofoid and White) Chitwood (2). On the other hand, tobacco plants (Nicotiana tabacum L.) infected with tobacco ringspot virus (TRSV) and ...

The root-knot nematode (RKN), Meloidogyne incognita, is an obligate, sedentary endoparasite that infects a large number of crops and severely affects productivity. The commonly used nematode control strategies have their own limitations. Of late, RNA interference (RNAi) has become a popular approach for the development of nematode resistance in plants. Transgenic crops capable of expressing dsR...

Root-knot nematodes (Meloidogyne incognita) cause substantial yield losses in vegetables worldwide, and are difficult to manage. Continuous withdrawal of environmentally-harmful nematicides from the global market warrants the need for novel nematode management strategies. Utility of host-delivered RNAi has been demonstrated in several plants (Arabidopsis, tobacco, and soybean) that exhibited re...

Wang, Q., Y. Li, Z. Handoo, and W. Klassen. 2007. Influence of cover crops on populations of soil nematodes. Nematropica 37:79-92. A pot experiment was carried out in south Florida to elucidate suppressive or antagonistic effects of several cover crops grown in rotation on soil nematode populations. The crops were two marigolds, Tagetes patula L. ‘Dwarf Double French Mix’ (MDF), and Tagetes pat...
