the root lesion nematode tea,pratylenchus loosi, is currently the most important damage-causing factor of tea in iran and all over the world. this nematode is considered as the most damage-causing factor of tea in many tea-producing countries including sri lanka, china, india, japan and bngladesh. in recent years, it’s also considered as a key disease and damage-causing of tea that cause to sev...

the influence of different initial inoculum densities of the root-knot nematode meloidogyne javanica on the growth of sage (salvia officinalis), root-knot development and nematode multiplication was investigated 90 days after inoculation under greenhouse conditions. with the increase in the nematode initial inoculum densities, shoot fresh/dry weight, shoot/root length and root fresh/dry weight ...

root-knot nematodes, meloidogyne spp., are one of the important plant parasitic nematodes of tomato in the world. the most suitable control method of plant parasitic nematodes is the use of resistance sources and tolerant cultivars. in the earlier studies, the results showed thatonly 2% (19 out of 537 varieties) were resistant and tolerant to the root knot nematodes. in the supplementary studie...

Nematode-suppressive soils are characterized by the ability of soil microbial communities to reduce populations plant-parasitic nematodes (PPN) either directly or inducing systemic resistance in plants. Various microorganisms have been recognized as antagonists PPN suppressive using culture-dependent and culture-independent methods. However, associations that form with nematode-conducive poorly...

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...

Fungi associated with sugar beet cyst nematode (Heterodera schachtii Schmidt) in W. Azerbaijan were isolated from different stages during 2002-2004 and studied. Some 300 fungal isolates were obtained. In this paper, 16 species belonging to nine genera are identified. Among them, three species viz. Lecanicillium aphanocladii, Myrothecium verrucaria andPlectosporium tabacinum are as new records t...

traditionally, in suburbs of tabriz city, northwest iran (gps 38˚06΄n, 46˚15΄e, mean temperature of 6.6-20.0°c, sandy loam soil type), different types of vegetables including cabbages have been cultivated for many years. the cabbage cyst nematode, heterodera cruciferae was reported as one of the plant parasitic nematodes infecting kohlrabi (brassica oleracea l. var. gongylodes) and white cabbag...

root-knot nemaode which causes extensive damage to legumes and cerealshas beenreported in many countries. the nematods has been observed on legumes, roots in manyregions of the world, causing swollen root and yield reduction. in order to evaluate the effect ofirrigation interval on reproductive traits of root-knot nematode, and the damage inflicteduponnavy bean, a study was conducted in 2011 in...

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...
