Root-knot nematode is one of the major pest vegetable crops that produces root galls in infected roots, seriously reducing farmer’s produce. According to statistics, phyto-parasitic nematodes affect 12.3% world’s each year, resulting yield losses. Most common species root-knot have been reported be vulnerable cucumber and they can reduce productivity by up 60% protected commercial farming. Till...

Background: Root-knot nematodes are known to cause significant damage to eggplants. New approaches by green silver nanoparticles (GSN) are used to control plant-parasitic nematode to avoid chemical nematicide hazards.Objectives: Analyses of the incorporation of different concentrations of nanoparticles on two different algae (Ulva lactuca and Turbinaria turbinata) were carried out. Fureth...

the present study is based on the investigation of a soil hyphomyces, paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode meloidogyne javanica on tomato in greenhouse conditions. p. lilacinus, effectively promoted the growth of plants inoculated with m. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

Soils and roots of field crops in low-rainfall regions of the Pacific Northwest were surveyed for populations of plantparasitic and non-plant-parasitic nematodes. Lesion nematodes (Pratylenchus species) were recovered from 123 of 130 non-irrigated and 18 of 18 irrigated fields. Pratylenchus neglectus was more prevalent than P. thornei, but mixed populations were common. Population densities in ...

The soil fumigant 1,3-dichloropropene (1,3-D) formulated with chloropicrin is viewed as a likely alternative for replacing methyl bromide in Florida when the latter is phased out in 2005. Therefore, it behooves us to learn more about using 1,3-D in deep, sand soils. Two trials were conducted on spring squash to determine the most effective rate of 1,3-D for the control of Meloidogyne spp. Rates...

Brassica plants once incorporated into soil as green manures have recently been shown to have biofumigant properties and have the potential of controlling plant-parasitic nematodes. In Washington State, plant-parasitic nematodes are successfully managed with synthetic nematicides. However, some of the synthetic nematicides became unavailable recently or their supply is limited leaving growers w...

The influence of plant resistance on the size of individual root-knot nematodes was determined in greenhouse experiments. Five genotypes of alyceclover were inoculated with second-stage juveniles of Meloidogyne incognita race 3 or M. arenaria race 1. Plants were harvested at selected intervals and stained for detection of the nematodes, which were dissected from the roots. Length, width, and sa...

Abstract Root-knot nematodes ( Meloidogyne spp.) cause serious damages on most crops. Here, we report a high-quality genome sequence of exigua (population Mex1, Costa Rica), major pathogen coffee. Its mitogenome (20,974 bp) was first assembled and annotated. The nuclear then constructed consisting 206 contigs, with an N50 length 1.89 Mb total assembly 42.1 Mb.

The infection of plants by obligate parasitic nematodes constitutes an interesting model for investigating plant cytoskeleton functions. Root knot nematodes have evolved the ability to manipulate host functions to their own advantage by redifferentiating root cells into multinucleate and hypertrophied feeding cells. These giant cells result from repeated rounds of karyokinesis without cell divi...
