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...

Abstract Background Eggplant is of great renown in Egypt and worldwide as it favorable high value vegetable crop. Yet, many plant-parasitic nematodes (PPNs) can penetrate the roots this plant feed on it, causing heavy losses its yield. Meloidogyne spp. (root-knot nematodes, RKNs) Rotylenchulus reniformis rank among these parasites Egypt. Main body abstract This review compiles PPN ecology, biol...

In South Asian countries, the lucrative production of peaches has been seriously threatened by an assortment biotic stresses especially nematodes. This situation compromises achievement sustainable development goals (SDGs) related to food security and zero hunger. Recently under changing climate, root-knot nematodes genus Meloidogyne have emerged as most damaging phytopathogenic nematodes, whil...

Pasteuria penetrans is an endospore-forming bacterial parasite of root-knot nematodes that has potential as a biological control agent. Biochemical investigations of P. penetrans are limited because of difficulty in obtaining large quantities of endospores free of plant debris and contaminating microorganisms. Our objective was to develop a technique for extraction and purification of P. penetr...

Mount St. Helens volcanic ash was incorporated into a loamy sand greenhouse soil mix to produce concentrations of 0, 0.5, 1.0, 2.0, 4.0, 8.0, 25, 50 and 100% ash. Chemical and physical properties of the various mixtures were determined. Three experiments were conducted in a greenhouse to determine if volcanic ash had any influence on root-knot nematode survival and infectivity. Tomato, Lycopers...

Root-knot nematodes limit carrot production around the world by inducing taproot forking and galling deformities that render carrots unmarketable. In warmer climates, Meloidogyne javanica and Meloidogyne incognita are most prevalent. In F2 and F3 progeny from the cross between an Asian carrot resistant to M. javanica, PI 652188, and a susceptible carrot, resistance response was incompletely dom...

A nematicide (fenamiphos) and a herbicide (EPTC) were injected into a sprinkler irrigation system separately and as tank mixtures and applied in 25.4 kl water/ha for nematode and weed control on snapbean. There were no differences (P = 0.05) between methods of injection of fenamiphos + EPTC on efficacy or crop response. The root-gall indices of cultivars Eagle and GV 50 were lower in fenamiphos...

Trichoderma sp. is one of the endophytic fungi, which is produce toxic culturefiltrate against plant pathogen e.g plant parasitic nematode. Experiments were conducted to in vitro bioassays of the antagonistic effects of culturefiltrate produced by endophytic fungi Trichoderma sp. in different medium on mobility and mortality of Meloidogyne-J2. Three different medium of culturfiltrate were inves...

Plant parasitic nematodes, including root knot nematode Meloidogyne species, cause extensive damage to agriculture and horticultural crops. As Vitis vinifera cultivars are susceptible to root knot nematode parasitism, rootstocks resistant to these soil pests provide a sustainable approach to maintain grapevine production. Currently, most of the commercially available root knot nematode resistan...
