Banana production is seriously hindered by Meloidogyne spp. all over the world. Endophytes are ideal candidates compared to pesticides as an environmentally benign agent. In the present study, endophytes isolated from banana roots infected by Meloidogyne spp. with different disease levels were tested in vitro, and in sterile and nature banana monoculture soils against Meloidogyne javanica. The ...

the effects of poultry manure and cow dung in comparison with the nematicide, carbofuran on the yield of okra infested with root-knot nematode meloidogyne incognita race 2 were investigated. two plots of 17×11 m, each naturally infested with the mentioned nematode, were selected for the study. treatments were poultry manure and cow dung each at the rates of 5 and 10 t ha-1, carbofuran 3g at the...

root-lesion disease, which is caused by pratylenchus loosi , is one of the most important diseases currently impacting iran tea plantations. this disease causes great economic crop impacts. northern provinces, which supply much of iran’s tea production, have been especially hard impact by root-lesion disease.the purpose of this study was to biological control the nematodes as one of the main se...

Larvae of Meloidogyne spp. were readily infected with the endoparasite Bacillus penetrans by exposure to an aqueous suspension of spores from infected root-knot nematode females, or by passage of larvae through a shallow layer (50 cm(3)) of spore-infested soil. Infection severely reduced motility of second-stage larvae through soil. Bacillus penetrans exhibited a distinct host specificity in th...

Combining effects of soil solarization and grafting on soilborne pathogens, plant height and yield in cucumber were compared in a greenhouse of Bati Akdeniz Agricultural Research Institute located in Antalya in 2008 fall season. The experiment was set in split plot design containing; 1, 2, 4 and 5 months soil solarization (MSS), and non-solarized control plots (NSC) on which grafted Maximus F1+...

Secreted proteins coded by parasitism genes expressed in esophageal gland cells mediate infection and parasitism of plants by root-knot nematodes. An essential parasitism gene, designated as 16D10, encodes a conserved root-knot nematode secretory peptide that stimulates root growth and functions as a ligand for a plant transcription factor. Plants were engineered to silence this parasitism gene...

make sure that the soil is not infested before planting and that the transplants are free of nematodes. The type of cover crop used in peach orchards can have a considerable effect on the degree of attack by root knot nematodes and consequently on the growth and yield of the trees. In experimental plots in Georgia, trees on plots where root knot resistant cover crops were planted produced about...

Pasteuria penetrans is a gram-positive, endospore-forming eubacterium that apparently is a member of the Bacillus-Clostridium clade. It is an obligate parasite of root knot nematodes (Meloidogyne spp.) and preferentially grows on the developing ovaries, inhibiting reproduction. Root knot nematodes are devastating root pests of economically important crop plants and are difficult to control. Con...

The ability of nematode-trapping fungi to colonize the rhizosphere of crop plants has been suggested to be an important factor in biological control of root-infecting nematodes. In this study, rhizosphere colonization was evaluated for 38 isolates of nematode-trapping fungi representing 11 species. In an initial screen, Arthrobotrys dactyloides, A. superba, and Monacrosporium ellipsosporum were...
