Abstract:

The work presented in this thesis evaluated the potential of integrated management of root-knot nematodes. Emphasis was given to the use of two complementary biological control agents, Paecilomyces lilacinus and Bacillus firmus, together with appropriate cultural practices including soil solarization and organic soil amendments, in comparison with the judicious use of chemical control. Use of soil amendments for nematode population suppression, demonstrated that application of fresh-chopped grass and brassicacaeous amendments suppressed root-knot nematode populations. After incubation of soil

Abstract:

Root-knot nematodes (Meloidogyne spp.) are serious root pathogens that affect commercial crops world-wide. The overall aim of this study was to develop techniques to identify plant genes expressed in specialised cells induced to feed these nematodes in order to develop a novel approach to host resistance. Little data exists on which root-knot nematode species are present in Western Australia. An initial study was carried out to identify species present in the major horticultural areas of WA. M. incognita, M. hapla, M. arenaria and M. javanica were isolated from a variety of crops with M. javan

Thesis (M.Sc. (Agriculture)) --University of Limpopo, 2017<br>Root-knot nematodes (Meloidogyne species) are the major soil-borne pests of tomato (Solanum lycorpesicum) plants. Due to the global withdrawal of effective chemical nematicides from the agrochemical markets, nematodes are difficult to control under the production systems. Currently, botanicals are being researched and developed as alternative to chemical nematicides with promising results, although they have challenge of phytotoxicity.

Abstract:

Plant resistance through grafting susceptible scions onto resistant rootstocks is an effective measure to supress root-knot nematode (RKN) populations and to reduce crop yield losses. However, the reiterative use of specific R genes could select virulent populations for those genes. Cucumis metuliferus is one promising rootstock for melon and cucumber, but there is little information regarding the host suitability to nematode populations from specific production areas, the effect on the population dynamics, the durability of the resistance, the rootstock-scion compatibility and the effect of t

Abstract:

Root-knot nematodes (Meloidogyne sp.) are sedentary endoparasites that infect roots of a wide range of plant species and cause considerable economic loss to many crops. Root-knot nematodes (RKN) transform selected root vascular cells into enlarged, multinucleate feeding sites called giant-cells that arise from repeated karyokinesis without cytokinesis. Giant-cells undergo extensive modifications of the cell wall architecture including cell wall thickening and the formation of ingrowths that act to increase the surface area of the plasma membrane to facilitate solute uptake by the nematode.

Abstract:

Plant parasitic nematodes are economically important crop pests: of these root-knot nematodes (Meloidogyne spp.) have the widest host range and are recognised as the most significant nematode pests of crop plants worldwide. Current control methods have serious limitations: natural resistance genes, chemicals and cultural practices are often not effective or are too expensive for large scale application. An alternative control strategy chosen here was to target and silence a conserved mechanism (RNA interference – RNAi) in the nematodes via transgenic plants. The RNAi pathway itself was studied

Over the years, potato production in South Africa has been affected by, among other factors, diseases and plant parasitic nematodes particularly root-knot nematodes (Meloidogyne spp.). In infected potato fields, root-knot nematodes cause great damage to the crop leading to substantial losses in yield and compromised produce quality. The direct a

Meloiodgyne incognita, one of the most aggressive plant parasitic nematodes species on potato in South Africa, belongs to a group of plant parasitic nematodes commonly known as root knot nematodes (RKN). This group of nematodes is widely distributed throughout the world. Meloidogyne spp. cause major economic losses to important crops such as potato and therefore decrease their market value in many countries across the world. The second stage juveniles are the only mobile and infective phase of the root knot nematode. As they infect host roots, they create wounds that can be used by other plant

Abstract:

To date biopesticides and biocides are studied as substitutes for their toxic synthetic ancestors.
