Information on some of its actual effects on banana plants and pests has been scarce. In: Luc M, Sikora RA, Bridge J, eds. Radopholus similis is a migratory endoparasite of plant roots and causes spreading decline in citrus. Genomic diversity between Radopholus similis populations from around the world detected by RAPD-PCR analysis. Radopholus similis and P. goodeyi are migratory endoparasitic nematodes, while H. multicinctus acts both as an ectoparasitic and endoparasitic nematode, invading the superficial layers of the root cortex and causing shallow lesions (Orion and Bar-Eyal, 1995). Plant-parasitic nematodes (PPNs) cause an estimated annual damage of over $100 billion in agriculture worldwide. ; JABB, 19(4): 1-19, 2018; Article no.JABB.45952, 2018 The burrowing nematode, Radopholus similis, is the most economically important nematode parasite of bananas, in addition to parasitising a range of other crops (Coyne & Kidane, 2018).Weakened, infected roots result in poor plant development and they are less able to provide anchorage to banana plants, which can lead to toppling of the entire plant. the main steps of alternative integrated plant-parasitic nematode management in banana crop-ping systems in the French West Indies. The burrowing nematode, Radopholus similis (Cobb, 1893) Thorne, 1949, is the key nematode pathogen, causing yield losses up to 75% . A novel, simple, rapid and highly sensitive assay and diagnostic tool for the burrowing nematode, Radopholus similis, was developed using a loop-mediated isothermal amplification (LAMP).The LAMP assay was targeted on the specific fragments of rRNA gene D2-D3 regions of R. similis.The detection limitation of the LAMP assay was as low as ten copies of plasmid DNA containing the target DNA, 10 fg . An alternative is to develop new banana hybrids with resistance to burrowing nematode. Radopholus similis is a migratory endoparasitic nematode primarily found in plant roots and widely known as a destructive pest of banana, citrus and black pepper. In Sri Lanka, an integrated management technique is adopted for control of R. similis and prevention of its spread in tea areas (Gnanapragasam, 1995). Extraction and processing of plant and soil nematodes. Radopholus similis was considered the original banana race, a parasite of banana but not citrus. The management of this pathogen is based on the application of granular nematicides combined with agro-nomic practices (7). similis. Download.

The burrowing nematode, Radopholus similis is considered to be the most destructive nematode associated with banana growth worldwide. The burrowing nematode Radopholus similis is among the most destructive pests of banana (Sarah et al., 1996).Plant yield losses as high as 50% have been observed under heavy nematode infestation (Speijer et al., 1999; Speijer and Kajumba, 2000).Currently, nematode management for resource-poor farmers mainly relies on the use of cultural methods such as pared and hot water-treated suckers . Appearance of dark red lesion on roots. However, soil texture plays a less important role on nematode population levels on banana (O'Bannon 1977). The burrowing nematode, Radopholus similis (Cobb, 1893) Thorne, 1949, is the key nematode pathogen, causing yield losses up to 75% (3). The concomitant infestation of M. incognita, R. similis and T. piperis in the roots of black pepper was reported high compared to their solitary infestation [9]. At present, there is few reports about R. similis in Mainland China. Further sampling of volunteer ginger (regrowth from previous crop) and crowsfoot (a weedy host of Radopholus similis) in February 2015 also did not detect any Radopholus similis. After two months, the plants are uprooted and their root system examined 2 . The study gives a better understanding of interaction between black pepper and its major nematode species Radopholus similis. Ginger, Zingiber officinale, is an erect, herbaceous perennial plant in the family Zingiberaceae grown for its edible rhizome (underground stem) which is widely used as a spice.The rhizome is brown, with a corky outer layer and pale-yellow scented center.
