The Plant Health Instructor. Commonly called as Gall-nematode. While some nematodes are free-living, others are parasitic and need other organisms (called hosts) to keep themselves alive 3.Once attached to their host, they divert nutrients and feed off of blood, tissues or pieces of cells to facilitate their own growth. As with other plant‐parasitic nematodes, indirect costs, such as the establishment of control measures, degradation of land quality, cost of quarantine procedures and loss of nematode‐free land for seed production, add to the direct losses caused by the impact on yield (Main et al., 1999). Plant-parasitic nematodes are costly burdens of crop production. 1.

These stylets function like hypodermic needles, taking in plant sap. Nematode feeding can result in diseased plants with symptoms such as stunting, yellowing, wilting, yield reduction, root galling and the formation of root lesions. In case of endoparasitic nematodes, three moults occur with in the host plant. Meloidogyne hapla . Anterior end contains stylet or spear measuring 8-10 micron in length. 3. There are 162 species of plant-parasitic nematodes from 35 different genera that have been identified from root and soil samples collected in vineyards (Lamberti, 1988). They induce a multi-nucleate feeding site close to the vascu lar bundle in the roots of their host plant and remain sessile for the rest of their life. • Plant-parasitic nematodes are production limiting in most grape producing regions • Species present will depend upon location ... name . 25-40% : Ring .

Nomenclature of plant parasitic nematodes 1. Plant-parasitic nematode infection is a global problem for agriculture and forestry. Nematodes - Plant Parasitic Nematodes. Due to the high toxicity of chemical nematicides, it is necessary to develop new control strategies against nematodes. These are sedentary endoparasites. 5. Plant-Parasitic Nematodes . 2. In South Africa, plant-parasitic nematodes have a negative impact on the production of good quality and economically viable grapes. The cuticle of a typical plant-parasitic nematode is transparent, thus allowing the viewing of internal systems when viewed under the microscope, . Plant-parasitic-nematodes represent a major threat to the agricultural production of different crops worldwide. A few plant parasitic nematode species form specialized structures, such as these white cysts of Heterodera, that can be observed with the unaided eye. Root-knot nematodes (Meloidogyne spp.) There is clearly a need for novel nematicides, because of the pitifully small repertoire of nematicides available and the effectiveness of losing or environmental prohibition of these nematicides. The economic impact of plant-parasitic nematodes on a Ubiquitous in nature, phytoparasitic nematodes are associated with nearly every important agricultural crop and represent a significant constraint on global food security. Chitin is the essential component of nematode eggshell and pharynx. Book : The biology of plant parasitic nematodes. All plant parasitic nematodes are able to penetrate plant cells by inserting the sharply pointed stylet found in their mouth cavities. In certain crops, such as bananas, losses may increase up to 30% (Sasser and Freckman, 1986). Other plant-parasitic nematodes can cause root knots or galls, leaf galls, injured root tips or root branching, or tissue problems such as lesions, patches of dying tissue, and twisted or distorted leaves. In Australia, plant-parasitic nematodes are problematic in all the different grape-growing regions (Nicol et al., 1999), and in South Africa grapevines are also host to a wide range of pest nematodes (Smith, 1977; Loubser & Meyer, 1987a; 1987b).
