In industrial banana cultivation, the control of weeds use chemical weeders harmful to human health and environment. In this study, the introduction of cover crops was considered as an alternative in banana plantations in South-eastern Côte d’Ivoire. The experiment was designed in Fisher’s block with three replications of three treatments that include use of cover crop species A. repens and D. adscendens as well as two chemical weeders constituting the third modality of the experiment. Parameters assessed on the growth recovery, development and resilience were better to A. repens than D....

Dans le cadre de la recherche de substances naturelles d’origine végétale comme alternative aux pesticides chimiques en agriculture, Terminalia ivorensis à laquelle l’on prête des vertus antifongiques a été utilisée dans cette étude pour évaluer in vitroet in vivola sensibilité de Fusarium oxysporum. L’activité antifongique in vitro a été évaluée par la méthode de double dilution sur milieu PDA avec des extraits aqueux et éthanoliques à 70 % de feuilles et écorce de Terminalia ivorensis comparativement au Mancozan 80 WP qui est un fongicide de référence très utilisé.Selon les resultats, s...

The mirid Sahlbergella singularis Hagl. causes major production losses in cocoa trees in Côte d'Ivoire. To deal with this problem, farmers make excessive use of synthetic chemical insecticides to improve crop yield. In order to reduce the chemical pollution risk, this study was initiated to assess the efficacy of a Bacillus thuringiensis var kurstaki HD-1 (Btk HD-1)-based biopesticide against S. singularis. The study was carried out in the laboratory in Petri dishes on two L4 larvae using the triplet method and, in the field, on a homogeneous population of L4 larvae, using a scattered bloc...

Cassava anthracnose is a plant disease that affects cassava stems, petioles and fruits. The aim of this study was to analyze the diversity of cassava anthracnose symptoms in Ivory Coast and then to identify and characterize the associated fungal genera. Surveys were carried out in all agricultural zones of the country from July to November, in 2014, 2015, 2016 and 2017. Infected samples consisting of stems cut with a small number of superficial cankers (0.3%), distorted stems (25.77%), and necrotic stems and petioles (65.18%) were collected. Also, withered and dried apical buds (8.76%) were ha...

Black pod disease caused by Phytophthora spp limits cocoa yield. This study aims at assessing the antifungal activity of Bacillus thuringiensis var. kurstaki HD-1 on pathogenicity of the parasite. The pea-based agar medium was treated either with Btk HD-1 suspension at different concentrations (C1 = 100%, C2 = 50% and C3 = 25%) or with the reference fungicide (3.33g/L). The medium distributed in petri dishes was inoculated with a 6 mm-diameter mycelial disc. After five days of incubation, safe and immature pods were inoculated with extracts taken from the previous culture medium. The cont...

Background: Herbal medicinal preparations are used as dietary supplements for disease prevention and as alternative/complementary medicine. The growing interest in herbal medicine raises the question of its safety and efficacy. Numerous recorded cases of intoxication and toxicological studies reveal that medicinal plants can be toxic, which hinders their safe use. Plant intoxications related to a variety of factors include plant organs and many extraction solvents. Little toxicological data on medicinal plants is available. The need to investigate is important for safe use. Imperata cylindrica...

The purpose of this study was to assess Chemical composition, total flavonoid and carotenoid contents with antioxidant and antimicrobial activities in crude and concentrated extracts of pepper fruit (Capsicum annuum var an.). The concentrated extract was obtained by reverse osmosis process. Radical scavenging potential was also determined using in vitro assay: 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radicals. The GC-MS analysis of concentrated extracts of C. annuum revealed the presence of major constituents such as lactic acid, valeric acid, 5-methoxy, butanedioic acid, phenylalanine, hexadecan...

La variabilité intraspécifique du teck suscite des réactions diverses chez les industriels du bois. Plusieurs paramètres de qualité sont couramment utilisés pour évaluer le teck. Bien que ces facteurs soient très intéressants, ils ne rendent pas compte de tous les aspects de la qualité du bois. Dans ce chapitre, nous passons en revue les méthodes normalisées d'évaluation des propriétés technologiques du teck et incluons également la composition chimique comme critère important. Cette dernière s'est avérée essentielle, car elle influence les propriétés technologiques les plus importantes, telle...

L'objectif de notre étude était d'évaluer les propriétés antibactériennes de divers extraits d'écorce de Pericopsis laxiflora sur Escherichia coli et Klebsiella pneumoniae , deux souches de bêta-lactamases productrices de spectre étendu (BLSE). La méthode des puits en gélose a été utilisée pour tester la sensibilité des souches bactériennes tandis que la concentration minimale inhibitrice (CMI) et la concentration minimale bactéricide (CMB) ont été déterminées par la méthode de dilution en milieu liquide. Les extraits méthanolique, acétique et éthanolique à 70 % ont donné des diamètres de zone...

The aim of this work was to study Borassus aethiopum Mart dried pulp nutritional value for its incorporation in poultry diets. Firstly, the mature fruits’ parts (sepals, peels, pulps, and seeds) were assessed. Secondly, the pulp was dried at 40, 50, 60, 70, and 80°C. Thereafter, analyses were performed for fat, protein, total sugars, Calcium (Ca), phosphorus (P), Magnesium (Mg), and fatty acid profile monitoring. As a result, the fruits weighed 1,591.35 grams, delivered 516.73 and 677.82 grams of pulp and seeds, respectively. Mainly, increasing heat adversely affected the outputs. Consequ...

Français Les graines de C. amaris (obtenues d'une ferme à Korhogo, en Côte d'Ivoire) ont été analysées pour leur composition lipidique. Les graines contenaient un niveau élevé de lipides (40 %). L'huile fraîchement extraite a donné des indices d'acide et de peroxyde de 6,06 et 34,44, respectivement. Les indices d'iode et de saponification étaient respectivement de 117,20 et 192,30. L'huile contenait divers acides gras. Les acides linoléique, oléique, palmitique et stéarique étaient les principaux acides gras présents. L'étude des composants insaponifiables de l'huile de graines a révélé que le...

The sapwood proportion in sawdust prior to extraction plays a crucial role in determining the effectiveness of extracts against wood-decaying fungi and crop-damaging insects. This study, centered on the sawdust of five durable wood species from Côte d’Ivoire, revealed that sapwood proportions in individual sawdust samples can be predicted either directly from the sawdust or by analyzing extracts obtained through ethanol-water extraction (50/50, v/v). The most accurate predictive models were developed for Milicia regia (Iroko) and Mansonia altissima (Bete). For Milicia regia, the model pe...
