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+...

Background: Root-knot nematodes are known to cause significant damage to eggplants. New approaches by green silver nanoparticles (GSN) are used to control plant-parasitic nematode to avoid chemical nematicide hazards.Objectives: Analyses of the incorporation of different concentrations of nanoparticles on two different algae (Ulva lactuca and Turbinaria turbinata) were carried out. Fureth...

Nematode management decisions should be based, in part, on knowledge of the damage threshold population density, and this value is likely to vary based on the level of resistance of the cotton cultivar. The damage functions of two cotton cultivars resistant to the root-knot nematode (Meloidogyne incognita) were compared with that of a susceptible cultivar in field microplots using a 3 x 7 facto...

Okra has significant area under cultivation in Africa and Asia, despite it been considered as a minor crop not much attention given to okra improvement international research program. Niger produced during 2008, 2794 t of 5288 ha with mean productivity 0.39 t.ha-1. This poor average is far below than the East (6.2 t.ha-1) North (8.8 t.ha-1). Non-availability varieties resistant local biotic str...

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...

When nematodes invade and subsequently migrate within plant roots, they generate cell wall fragments (in the form of oligogalacturonides; OGs) that can act as damage-associated molecular patterns and activate host defence responses. However, the molecular mechanisms mediating damage responses in plant-nematode interactions remain unexplored. Here, we characterized the role of a group of cell wa...

In healthy cotton, except for random occasional occurrence in cortical cells, terpenoid aldehydes (TA) are localized in the epidermis and, even there, are absent from the tip 2-4 cm of the root. Since constitutive TA do not occur in the endodermis and stele of the root, they cannot be effective agents against the development of the sedentary stage of the root-knot nematode, Meloidogyne incognit...
