A simple and applicable technique was developed for the detection of soil infestation with rice rootknot nematode, Meloidogyne graminicola by farmers themselves at their fields. The collected soil samples from root-knot nematode infested fields were diluted by adding sterilized sand in the ratio of 1: 1, 1: 3, 1: 7, 1: 15, 1: 31 and 1: 63 and sown with sprouted rice seeds (cv MUT 7029) for dete...

Abstract Passion fruit (Passiflora spp.) yield is limited by several factors, including soil pathogens, such as Rotylenchulus reniformis (the reniform nematode) and Meloidogyne incognita Southern root-knot nematode). Understanding the behavior of different cultivars, within species passion could be important asset to search for sources resistance, therefore effective management phytonematodes. ...

Selected cotton cultivars were evaluated for resistance to the southern root-knot nematode, Meloidogyne incognita, in greenhouse and field experiments. Cotton cultivars LA 887, Auburn 634, and NemX cotton were highly resistant to three North Carolina populations of root-knot nematode in greenhouse experiments compared to susceptible cultivars. The relative susceptibility of cultivars tested in ...

From this study we could conclude that, resistant cultivars are the single effective solution to management of root-knot nematode population avoid crop losses. Also, it is essential use in situations where nematodes present and when control advantageous yields. However, reported moderately cultivars, viz. Gujarat Rajmash, Amber (IPR 96-4) HUR15 belong secondary gene pool with cross-compatibilit...

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...

Soybean breeding lines and reported sources of nematode resistance were evaluated in repeated greenhouse tests for resistance to North Carolina populations of the soybean cyst nematode Heterodera glycines, reniform nematode Rotylenchulus reniformis, and the root-knot nematode species Meloidogyne incognita, M. arenaria, and M. arenaria. Lines from the soybean breeding program in Missouri that ha...

root-knot nematodes ( meloidogyne spp.) are important group of plant pathogens that have extensive hosting range and are caused for significant damage to agricultural products annually. various management strategies of control on nematodes has been used, but the application of plant products is one of the promising methods for nematode control. in this study, inhibitory effect of essential oils...

among fungi, species of the genus paecilomyces are considered as promising biological control agents with high potential to reduce root-knot nematode (rkn) and other nematode populations. in this research we investigated a soil hyphomycetes, paecilomyces marquandii and its pathogenicity on eggs of rkn in vitro. in greenhouse test, root weight, plant length, fresh weight and dry weight of plants...
