Aim: In Côte d'Ivoire, several food products are made from cassava. However, this production generates effluents such as wastewater responsible for soil, as well as water and air pollution. Meanwhile, cassava wastewater can be used as an inexpensive substrate for the production of biopesticides, such as Trichoderma virens, a bio-control agent for black pod disease. This could address both the problems of cassava wastewater treatment and the use of conventional synthetic substrates for biopesticide production. Methodology: The experiments described here were conducted using the cassava w...

Black pepper (Piper nigrum L.) is a globally important spice crop. In recent years, black pepper production has faced challenges due to various factors, including diseases. However, the black pepper cultivation is significant in Cote d'Ivoire, the specific diseases affecting the crop have not been comprehensively characterized. This study aimed to identify and characterize fungal diseases of black pepper in Cote d'Ivoire. Surveys were conducted in major black pepper-growing regions from November 2019 to July 2021. Samples of symptomatic leaves, stems, berries, and soil were collected from blac...

Le présent travail vise à contribuer à la connaissance de la composition et de la diversité floristiques des adventices des vergers de l'anacardier dans la zone de savane de Côte d'Ivoire. Dans chacun des 261 vergers de l'anacardier visités dans les 10 antennes de production d'anacarde, une ou deux placette(s) de 100 m2 ont été installées et prospectées pour l'inventaire des adventices selon que le verger de l'anacardier est à couronnes homogènes ou hétérogènes. Dans les 261 vergers ainsi prospectés, 438 espèces d'adventices appartenant à 73 familles et 276 genres ont été recensées. Les famill...

L'anthracnose est une maladie fongique de l'anacardier ( Anacardium occidentale L.) causée par Colletotrichum sp. Cette maladie cause de nombreux dégâts dans les vergers d'anacardiers en Côte d'Ivoire. L'objectif de cette étude était d'isoler des isolats présumés de bactéries telluriques et d'évaluer leurs effets sur la croissance de Colletotrichum sp responsable de l'anthracnose de l'anacardier en Côte d'Ivoire. À partir d'échantillons de sol, les bactéries ont été isolées et leurs activités antifongiques ont été évaluées in vitro . Ces activités ont ensuite été évaluées sur la croissance myc...

Français L'objectif de cette étude était d'évaluer l'impact d'un ensemble de variables (agronomiques, géographiques et climatiques) sur la propagation de l'anthracnose du manioc à l'échelle nationale en Côte d'Ivoire. Une enquête menée entre 2014 et 2017 a permis de déterminer l'incidence et la gravité de cette maladie dans les exploitations de manioc à l'aide d'une échelle de notation de l'infection. L'infection des exploitations a augmenté des exploitations saines (1 %) aux exploitations infectées par les graminées (4 %). De plus, des taux d'infestation élevés et des différences ont été obse...

The asymmetric unit of the title compound, C17H12O4, consists of two independent mol-ecules. The chromen-2-one ring and the 4-methyl-benzoate side chain are inclined to one another at a dihedral angle of 64.79 (10)° in one mol-ecule and 88.3 (1)° in the other. In the crystal, mol-ecules form R 2 (2)(8) centrosymmetric dimers via C-H⋯O hydrogen bonds. These dimers are stacked by C-H⋯O hydrogen bonds, resulting in R 2 (2)(18) and R 3 (2)(16) ring motifs. π-π stacking inter-actions between two parallel chromen-2-one rings, with centroid-centroid distances of 3.743 (1) and 3.771 (1) Å, are also pr...
