Background: The root-knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood reniform Rotylenchulus reniformis (Linford Oliveiro) have been found consistently associated with plant damage reduced yield of chickpea (Cicer arietinum L.), important pulse (grain legume) crop India. Methods: Seeds were soaked in S, S/2, S/4 extracts rice polish 0.1, 0.3, 0.5% solution pyridoxine for 4 h. Fo...

the non-defoliant strain of verticillium dahliae (ss-4) was isolated from olive groves showing disease symptoms in toshan area of southern gorgan city. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and following identification it was propagated on tomato seedlings cv. rutgers. one-year-old seedlings of olive cultivars, zard, roghani, koroneiki and manzani...

verticillium wilt verticillium dahliae is now a days commonplace in olive orchards in north of iran. root-knot nematode, meloidogyne javanica, as well is one of the most widely disseminated plant parasitic nematodes in olive orchards of iran. this study was arranged to find the effects of two sets of pot beds on these pathogens' interaction. microsclerotia of verticillium dahliae and j2s o...

An established arbuscular mycorrhizal symbiosis suppresses further mycorrhization. It is not clear whether the observed suppressional effect is linked with the level of root colonization or not. In the present work we studied the effect of the degree of root colonization by the arbuscular mycorrhizal fungus Glomus mosseae on further root colonization by G. mosseae. At different time points barl...

Abstract Background Bacterial bioagents, Pseudomonas fluorescens , P. putida Bacillus amyloliquifaciens and B. megaterium have management potential against root-knot nematode (RKN), Meloidogyne incognita in bottle gourd. Results Field laboratory experiments were conducted to evaluate the effect of bacterial bioagents 1% WP (2 × 10 6 CFU/g), 8 9 CFU/g) on egg hatching juvenile mortality nematode...

The root-knot nematode (Meloidogyne spp.) is one of the principal nematode pests of field and vegetable crops in the southern United States (6). Meloidogyne spp. are generally not uniformly distributed in naturally infested field sites, and sites frequently contain more than one species, thus complicating the evaluation of breeding lines for nematode resistance. To facilitate evaluation of nema...

rhizosphere soil samples were collected from olive orchards of golestan, guilan, zanjan and qom provinces. fluorescent pseudomonad strains were isolated from the collected samples on king’s b medium and their phenotypic features characterized as based on the standard bacteriological methods. for all the tested strains oxidase reaction, fluorescent pigment, growth at 4?c and arginine dihydrolase...

The root-knot nematode (RKN) Meloidogyne incognita infects a large host range causing enormous agricultural losses. Although the control of this pest is mainly based on use chemical pesticides, natural alternatives are currently being largely considered, especially plant-derived molecules, as allelochemicals and plant extracts. Solanum stramonifolium Solanaceae family has been studied for its p...

SUMMARY Transgenic tobacco and Arabidopsis thaliana carrying the Arabidopsis endo-1,4-beta-glucanase (EC 3.2.1.4) Cel1 promoter fused to the beta-glucuronidase (GUS) reporter gene were infected with the root-knot nematode, Meloidogyne incognita, and either the tobacco cyst nematode, Globodera tabacum (tobacco), or beet cyst nematode, Heterodera schachtii (Arabidopsis). Cel1-driven GUS expressio...

Application to the soil of the insecticide dimethoate had no effect on the growth of soybean colonized by the arbuscular mycorrhizal (AM) fungus Glomus mosseae and by the indigenous AM fungus. The application of the recommended concentration of dimethoate decreased the percentage of colonization of soybean by the indigenous AM population, but no significant effect was observed on the colonizati...
