Influence of Two Cover Crops (Arachis repens L. and Desmodium adscendens Sw.) on Root Infestation of the “Great Dwarf” Dessert Banana Cultivar (Musa sp.) by Plant-parasitic Nematodes in Southeast Côte d’Ivoire

Context: In Côte d’Ivoire, industrial banana plantations are faced with the problem of weediness. However, use herbicides as a means control presents significant risks for human health and environment. The abandonment these products more ecological alternatives such cover crops is imminent.
 Aims: This study aimed to compare relative abundance density main plant-parasitic nematodes in roots according three weed management treatments.
 Study Design Methodology: experimental design was three-repeat Fisher block treatments consisting implementation A. repens D. adscendens spraying two synthetic (glufosinate glyphosate) management. were assessed quarterly after extraction by rapid double centrifugation-flotation method enumeration under an optical microscope.
 Results: Both plants had their infested major parasitic evaluated (Radopholus similis, Pratylenchus spp., Helicotylenchus Meloidogyne Rotylenchulus reniformis Hoplolaimus pararobustus). These infestations not function treatments. Compared herbicides, used ground did significantly increase or decrease nematode dynamics plots. Individuals extracted from crops, particularly adscendens, numerous than plants. terms proportions, R. spp. most abundant. H. pararobustus well various (plant parasites: Hirschmanniella Xiphinema ..., non-plant fungivorous, carnivorous, bacterivorous, ...) minority.
 Conclusion: results, those repens, could be useful biological, sustainable without important pest pressure.
