Root-knot nematode, Meloidogyne incognita (Kofoid and White) is one of the most destructive plant parasitic nematode species in almost all agriculture horticulture crops Sri Lanka. Biologically sound controlling measures against this has been attempted from long past with ambiguous efficacy. This paper highlights nemato-toxic potential crude leaf extract Annona glabra, extracellular metabolites...

Cortada, L., P. Manzano, F. J. Sorribas, C. Ornat, and S. Verdejo-Lucas. 2010. The resistance response of Solanum huaylasense accession LA1358 to Meloidogyne spp. Nematropica 40:31-40. Pathogenicity tests were performed to determine resistance in the wild tomato Solanum huaylasense to four populations of Meloidogyne spp. The S. huaylasense accession LA1358, the root-knot nematode resistant toma...

Sedentary endoparasitic nematodes of plants induce highly specific feeding cells in the root central cylinder. From these, the obligate parasites withdraw all required nutrients. The feeding cells were described as sink tissues in the plant's circulation system that are supplied with phloem-derived solutes such as sugars. Currently, there are several publications describing mechanisms of sugar ...

Root-knot nematodes (RKNs) are sedentary biotrophic parasites that induce the differentiation of root cells into feeding cells that provide the nematodes with the nutrients necessary for their development. The development of new control methods against RKNs relies greatly on the functional analysis of genes that are crucial for the development of the pathogen or the success of parasitism. In th...

in this research, the ability of bacillus strains in suppression of mycelial growth and conidial germination of b. cinerea against botrytis fruit rot of strawberry were evaluated in three cultivars of strawberry including quineliza, paros and kurdistan. results indicated that among 32 strains of bacillus, ten strains showed strong inhibitory effects against b. cinerea using the plate assay and ...

Abstract Root knots, caused by Meloidogyne spp. is among the plant pathogens that lead to significant yield loss in patchouli plants. Farmers have used synthetic nematicides control pathogen for many years. In fact, chemicals not only harm environment but also might degrade quality of agriculture products. Therefore, this study, we examined several dosages Bacillus thuringiensis (Bt) on Pogoste...

Root-knot nematodes, particularly Meloidogynejavanica (Treub.) Chitwood, 1949 and M. incognita (Kofoid and White) Chitwood, 1949, are among the most important pathogens of carrots (Daucus carota L.) in Brazil. They damage tap roots by galling, digitation, and constriction, resulting in lower market value (3). Even low soil densities of root-knot nematodes have been reported to reduce marketable...

Organic soil amendments have been employed as an alternative to or in combination with, chemical nematicides and cultural practices to control plant-parasitic nematodes. Rye (Secale cereale L.) has been shown to be effective in minimizing the damage caused by root-knot nematodes (Meloidogyne incognita (Kofoid and White) Chitwood) when grown as a cover crop and then incorporated into the soil pr...

Management of Meloidogyne incognita (root-knot nematode) in cotton in the United States was substantially affected by the decision to stop production of aldicarb by its principle manufacturer in 2011. The remaining commercially available tools to manage M. incognita included soil fumigation, nematicide seed treatments, postemergence nematicide application, and cultivars partially resistant to M...
