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...

Meloidogyne enterolobii is widely considered to be an aggressive root-knot nematode species that is able to reproduce on root-knot nematode-resistant tomato and pepper cultivars. In greenhouse experiments, M. enterolobii isolates 1 and 2 from Switzerland were able to reproduce on tomato cultivars carrying the Mi-1 resistance gene as well as an N-carrying pepper cultivar. Reproduction factors (R...

Perla, David E. M.S., Purdue University, August, 2014. Management of Root Knot Nematode (Meloidogyne incognita) in Indiana Soybeans. Major Professors: Ricky Foster and Virginia Ferris. The aim of this project was to evaluate different strategies for management of Root Knot Nematode (RKN) on soybean and tomato in Indiana. Seed treatments were evaluated under field and greenhouse conditions, but ...

The effects of soil management systems on root-knot nematode (Meloidogyne incognita) eggs and gall incidence on tomato (Lycopersicon esculentum) and cucumber (Cucumis sativus) following tomato were evaluated. Soil was collected from a replicated field experiment in which six management systems were being assessed for vegetable production. Soil management systems were conventional production, or...

introduction: root-knot nematodes (meloidogyne spp.) are important plant pathogens that make large damage to the crops. the activity of root-knot nematode and reaction of host plant results in the development of several knots on the root, which interrupts water and food absorption system of the plant. among popular methods for controlling root-knot nematodes are physical methods (soil solarizat...

in this study, high biocontrol potentially bacillus isolates, against root knot nematode were evaluated from viewpoint of biofilm formation and root colonization in vitro. among 139 bacillus isolates from tomato rhizosphere of several regions of razavi khorasan, 15 strains which show more ability to prevent egg hatch and cause larvae mortality of meloidogyne javanica, were tested in biofilm ass...

greenhouse studies showed in the transplant of tomato that two weeks before infection with nematodes with two species of mycorrhizal g. mosseae and g. intraradices had been inoculated, were significantly offseted the reduction of growth that had been done by nematodes. it should be noted that the percentage of root colonization with two species 66.3% and 62.2% respectively and based on this stu...

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 ...
