A drip irrigation delivery system was used to infest field sites with the plant-parasitic root-knot nematodes, Meloidogyne incognita. Juvenile or egg inocula passed through the system without blockage of emitters or harm to the nematodes. Field sites so infested were available for experimentation. Delivery of approximately 5 x 10 to 10 juveniles or 10 to 3 x 10 eggs per emitter through the drip...

A system for monitoring movement of the free-living second stage juveniles of root-knot nematodes (Meloidogyne spp.) using digital image analysis is described. The method is based on the analysis of video sequences of movement of individual random nematodes encumbered with or without Pasteuria penetrans endospores. Software packages were used to grab video images, to process images and to monit...

The aim of this review was to undertake a survey of researchers working with plant-parasitic nematodes in order to determine a 'top 10' list of these pathogens based on scientific and economic importance. Any such list will not be definitive as economic importance will vary depending on the region of the world in which a researcher is based. However, care was taken to include researchers from a...

Root-knot nematodes (RKN; Meloidogyne incognita) are phytoparasitic that cause significant damage to crop plants worldwide. Recent studies have revealed RKNs disrupt various physiological processes in host plant cells induce gall formation. However, little is known about the molecular mechanisms of formation induced by nematodes. We previously found RNA expression levels some genes related micr...

The presence of plant-parasitic nematodes causing crop loss every year had been overlooked in the existing fruits, vegetables and flowers cultivation system Bangladesh. Therefore, study was conducted to isolate identify plantparasitic from soil infected plant-parts fruits (banana, orange), (pointed gourd, tomato brinjal) flower (gerbera) districts Jashore, Jhenaidah, Gazipur Sylhet during 2017-...

Research was initiated to physically characterize the mitochondrial genomes of several Meloidogyne spp. and host-races, to address questions regarding their systematics and dispersal, and to assess the possibility of developing molecular diagnostics for these nematodes. Techniques were developed for purification and rapid detection of mitochondrial DNA from root-knot nematodes. Mitochondrial DN...

Resistance of pepper species (Capsicum annuum, C. baccatum, C. chinense, C. chacoense, and C. frutescens), cultivars and accessions to the root-knot nematodes Meloidogyne incognita race 2 and M. javanica, and their graft compatibility with commercial pepper varieties as rootstocks were evaluated in growth chamber and greenhouse experiments. Most of the plants tested were highly resistant to M. ...

To concurrently control root-knot nematodes and treat pig manure further clarify the mechanism of anaerobic digestion slurries on nematodes, optimal conditions for producing volatile fatty acids (VFAs) were studied, relationship between carboxyl group in fermentation mortality rate was also researched. When condition parameters set as initial pH=10.0, temperature 25 °C, total solid (TS) loading...

Effectors are specific proteins secreted by nematodes into plant cells that facilitate their parasitism to host plants. Inactivation of these effectors could reduce the parasitic ability on plants and damage caused nematodes. Gene Minc14137encodes an effector unknown function is cloned from Meloidogyne incognita. Artificial microRNAs capable inactivating gene Minc14137 were synthesised inserted...

A 3-year field rotation study was conducted to assess the potential of switchgrass (Panicum virgatum) to suppress root-knot nematodes (Meloidogyne arenaria), southern blight (Sclerotium rolfsii), and aflatoxigenic fungi (Aspergillus sp.) in peanut (Arachis hypogaea L.) and to assess shifts in microbial populations following crop rotation. Switchgrass did not support populations of root-knot nem...
