Data on tomato fitness improvement by arbuscular mycorrhizal fungi (AMF) remain patchy. The present study was initiated to evaluate the effect of the period of AMF inoculation as well as the level of mineral manure on tomato growth. The experiment took place from June to October 2016, in the West African Science Service Center on Climate Change and Adapted Land Use greenhouse. AMF inocula were applied to seeds and/or transplants, each receiving three different levels of chemical fertilizer. The impact of the inoculation period and the level of fertilization, were assessed on plant growth param...

AbstractCassava growth in Côte d’Ivoire is affected by the variation in weather conditions and various pests and diseases. Cassava Bacterial Blight is a particularly destructive disease influenced by weather conditions which can lead to 100% yield loss. In order to provide sustainable control strategies, it is essential to understand the occurrence and the behaviour of the disease in the different ecological zones in Côte d’Ivoire. Surveys were carried out in cassava fields from 2014 to 2017 in the seven Ivorian agro-ecological zones. These fields were assessed for the disease presence/absence...

L’objectif de ce travail est d’évaluer le pouvoir fongicide des feuilles de Mallotus oppositifolius sur Phytophthora sp. et Fusarium sp. deux champignons phytopathogènes dans le cadre de la recherche de substances naturelles d’origine végétale comme alternative aux pesticides chimiques en agriculture. Une enquête ethnobotanique réalisée auprès de quarante tradipraticiens de santé du District de Yamoussoukro sur les Euphorbiaceae médicinales a permis d’identifier treize espèces. L’étude a montré que les maladies de la peau (36%) étaient majoritairement traitées par ces Euphorbiaceae dont Mallot...

Bacillus thuringiensis subspecies kurstaki HD-1 (Btk HD-1) has been widely used for five decades as a leading biopesticide for its ecological action. However, this biopesticide often has challenges related toits costs of production and its formulation. The purpose of this work was to evaluate a novel low-cost Btk HD-1-based biopesticide production method using sugar cane molasse enriched with yeast extracts. After determining their content, Four growth media containing variable proportion of molasses and yeast extracts were formulated, then inoculated with (BtkHD-1) and incubated to 30 ± 1 °C....

A critical reflection based on literature is presented to the lectures given at the symposium "A clinical approach to growth" at the 73rd Réunion Scientifique of the Société Française d'Orthopédie Dento-Faciale in Deauville, France, on may 13th, 2000. Uncertainty is expressed about the long-term effects on the growth pattern after early surgery in children. It is apparent that conventional dentofacial orthopedics have a limited long-term effect on the growth pattern. Surgical as well as non-surgical (orthopedic) approaches are plagued by complications and relapse. The need for unbiased clinica...

An ethnobotanical survey was carried out in the District of Yamoussoukro (Central Côte d’Ivoire) in order to evaluate the biocontrol potential against fungal plant pathogens, of Euphorbiaceous plants used as medicines by the native population. Twelve (12) species were collected. The antifungal activity was assessed using the two-fold dilution method on PDA medium with ethanolic and aqueous extract derived from leaves of six plants. Results pointed out that only 70% ethanolic extracts from Alchornea cordifolia (EE13) possess fungicidal properties on both Fusarium sp. and Phytophthora sp. The an...

Chemical insecticides have been commonly used against the black weevil, Cosmopolites sordidus, in banana plantations which caused huge economic and agricultural losses. Despite their benefits, pesticides can be hazardous to both humans and the environment. Intensive research in substituting chemical insecticides with biological control agents have been driven. The biological and molecular characteristics of ten strains of Metarhizium spp, isolated from dead weevils, collected in banana plantation in Côte d'Ivoire were studied. The study aims to identify the species of Metarhizium sp. The biolo...

The prevalence of viruses in pepper crops grown in open fields in the different agro‐ecological zones (AEZs) of Côte d'Ivoire was surveyed. Pepper veinal mottle virus (PVMV; genus Potyvirus ) and Cucumber mosaic virus (CMV; genus Cucumovirus ) were the most frequent viruses among those surveyed, while tobamoviruses (genus Tobamovirus ) were detected at low frequency. PVMV showed a high heterogeneity across AEZs, which may be related to climatic, ecological or agronomical conditions, whereas CMV was more homogeneously distributed. The molecular diversity of CMV and PVMV were analysed from parti...

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...

Background and Objective: Cassava (Manihot esculenta Crantz) is the second largest food crop in Côte dʼIvoire after yam.It is cultivated for its fleshy roots rich in starch and for the richness of its leaves in minerals (calcium, phosphorus and iron).However, this crop is subject to numerous biotic constraints of which one of the most formidable is bacterial blight caused by Xanthomonas axonopodis pv.manihotis.In Côte dʼIvoire, no concrete study has been conducted on this emerging disease with the aim of reducing its impact on the yield of tuberous roots of traditional and improved varieties.T...

La connaissance de la dynamique de l'agrobiodiversité est nécessaire pour percevoir les évolutions néfastes de l'érosion génétique et entreprendre des stratégies de conservation. L'objectif du présent travail a été d'étudier la variabilité phénotypique des accessions et leur structuration sur la base de 24 variables. Quarantequatre accessions de manioc ont été collectées dans différentes zones de production de la Côte d'Ivoire. La description des différentes accessions (variables qualitatives) et la mesure des paramètres agronomiques (variables quantitatives) ont permis d'établir une classific...
