Abstract Tiafenacil is a new non-selective protoporphyrinogen IX oxidase (PPO)-inhibiting herbicide with both grass and broadleaf activity labeled for preplant application to corn ( Zea mays L.), cotton ( Gossypium hirsutum L.), soybean [ Glycine max (L.) Merr.], and wheat ( Triticum aestivum L.). Early-season soybean emergence and growth often coincide in the U.S. Midsouth with preplant herbicide application in later-planted cotton and soybean, thereby increasing opportunity for off-target herbicide movement from adjacent fields. Field studies were conducted in 2022 to identify any deleteriou...

Tiafenacil is a new nonselective protoporphyrinogen IX oxidase-inhibiting herbicide with both grass and broadleaf activity labeled for preplant application to corn, cotton, soybean, and wheat. Early-season cotton emergence and growth often coincides in the Mid-South with preplant herbicide application in later planted cotton and soybean, thereby increasing opportunity for off-target herbicide movement from adjacent fields. Field studies were conducted in 2022 to identify any deleterious impacts of reduced rates of tiafenacil (12.5 – 0.4% of the lowest labeled application rate of 24.64 g ai ha-...

Euphorbia heterophylla est une adventice qui popularise 70% des parcelles cotonnières du nord de la Côte d’Ivoire. Une enquête, en vue de sa valorisation, a révélé ses effets profertiles. Dans le but de vérifier ces effets sur la fertilité du cobaye mâle, l’étude des activités fertilisantes de sa pousse sèche a été menée. A cet effet, une analyse du taux des hormones gonadotropes dans le sang après 15 jours, 30 jours et 60 jours de complémentation avec 5 g ou 10 g et des tests de motilité, vitalité, concentration et de formes des spermatozoïdes le 60ieme jour, ont été effectués après administr...

The significant decrease in the water level of the Nanan agricultural dam is becoming very worrying for rice farmers. In this study, we analyzed the land use dynamics of dam watershed and its impacts on morphological characteristics and reservoir inflow. This analysis was conducted by coupling the satellites images of Landsat sensors over a thirty years, Digital Terrain Model (DTM) and direct field observation. The classification of Thematic Mapper (1986), Enhanced Thematic Mapper+ (2000) and Operational Land Imager (2015) images has gave respectively an overalls accuracies of 99.01%, 96.62% a...

Abstract BACKGROUND Regulations in 2021 required the addition of a volatility reduction agent (VRA) to dicamba spray mixtures for postemergence weed control. Understanding the impact of VRAs on weed control, droplet dynamics, and spray pH is essential. RESULTS Adding glyphosate to dicamba decreased the solution pH by 0.63 to 1.85 units. Across locations, potassium carbonate increased the tank‐mixture pH by 0.85 to 1.65 units while potassium acetate raised the pH by 0.46 to 0.53 units. Glyphosate and dicamba in tank‐mixture reduced Palmer amaranth control by 14 percentage points compared to dic...

Au cours de ces dernières années, les pouvoirs publics ivoiriens ont fait de l'industrialisation l'un des maillons essentiels du développement, après le succès de l'agriculture. Mais la mise en oeuvre de cette politique pose parfois des problèmes d'environnement à Abidjan. La présente étude a pour objectif principal d'évaluer à travers six paramètres (T °C, pH, DCO, DBO5, MES et MGT), les impacts environnementaux négatifs des effluents industriels dans le milieu urbain d'Abidjan. Pour ce faire, des analyses physico-chimiques de 36 échantillons de rejets industriels, ont été réalisées. A l'exce...

The increased pressures on water resources linked to climate and societal changes are recognized as global challenges. The objective of this study is to analyze the impacts of climate change on the water stress of populations in the N'zi (Bandama) watershed in Ivory Coast.

Abstract Background Wetlands and irrigated agricultural crops create potential breeding sites for Anopheles mosquitoes, leading to a heterogeneity in malaria transmission. In agricultural areas, heterogeneity of malaria transmission is often associated with the presence of hotspots consisting of localized clusters of higher transmission intensity. This study aims to identify micro-geographic hotspots of malaria transmission in an agricultural setting using a multidisciplinary approach. Methods Two cross-sectional surveys were conducted at the end of the dry season and at the peak of the rainy...

Abstract Background Wetlands and irrigated agricultural crops create potential breeding sites for Anopheles mosquitoes, leading to a heterogeneity in malaria transmission. In agricultural areas, heterogeneity of malaria transmission is often associated with the presence of hotspots consisting of localized clusters of higher transmission intensity. This study aims to identify micro-geographic hotspots of malaria transmission in an agricultural setting using a multidisciplinary approach.

This work aimed to test the hypothesis that the combination of arbuscular mycorrhizal fungi (AMF) and accumulation of silicon (Si) in banana plants via its uptake and transport by the fungus reduces the incidence of Black Leaf Steak Disease (BLSD) caused by Pseudocercospora fijiensis. Methods: A pot experiment was conducted to compare BLSD symptoms on leaves of banana plants colonized or not by the AMF Rhizophagus irregularis MUCL 41833 and exposed or not to Si added to the growth substrate. Results: A marked increase in plant growth parameters (i.e., pseudostem diameter and height, leaf surfa...

This paper explores the issue of partial shading (PS) in photovoltaic systems and proposes a solution using the Flying Squirrel Search Optimization (FSSO) algorithm. PS results in power losses, and our study aims to enhance photovoltaic energy production by introducing a new Maximum Power Point Tracking (MPPT) controller based on the FSSO algorithm. This paper presents a controller designed to efficiently track the maximum power in the presence of partial shading. The controller uses the Modified ODD-EVEN (MOE) configuration, the Modified Symmetrical Array (MSA), and the Total-Cross-Tied (TCT)...

Fermentation is a complex phenomenon well studied which still provides challenges to brewers. In this study, artificial neural network, precisely multi layer perceptron and recurrent one were utilised for modelling either static (yeast quantity to add to wort for fermentation) or dynamic (fermentation process) phenomena. In both cases, the simulated responses are very close to the observed ones with residual biases inferior to 4.5%. Thus, ANN models present good predictive ability confirming the suitability of ANN for industrial process modelling.

Abstract This paper presents an experimental study focused on the behavior of non-cohesive soils presenting structural heterogeneities subjected to internal erosion due to suffusion. The suffusion tests were performed by applying a downward seepage flow under multi-staged hydraulic gradient. Experiments were carried out at the scale of a soil sample. Soil samples with structural homogeneity and soil samples with structural heterogeneities were tested. Homogeneous soil samples were used for comparison. Two heterogeneity configurations based on fines content (15% and 25%) and density index (ID =...

The use of Learning Games (LGs) in schools is a success factor for students.The benefits they bring to the learning process should be widely disseminated at all levels of education.Currently, there are thousands of LGs that cover a large variety of educations fields.Despite this large choice of LGs, very few are used by teachers, due to the difficulty of finding and selecting suitable LGs.The aim of this paper is to propose an extraction model that will automatically collect the information about LGs directly from their web pages, in order to index them in a catalogue.The proposed ADEM (Automa...

Abstract Field studies were conducted in 2021 in Kibler and Augusta, AR, to determine the effect of winter cover crops and cultivar selection on weed suppression and sweetpotato [ Ipomoea batatas (L.) Lam.] yield. The split-split-plot studies evaluated three cover crops [cereal rye ( Secale cereale L.) + crimson clover ( Trifolium incarnatum L.)], [winter wheat ( Triticum aestivum L.) + crimson clover], and fallow; weeding (with or without); and four sweetpotato cultivars (‘Heartogold’, ‘Bayou-Belle-6’, ‘Beauregard-14’, and ‘Orleans’). Heartogold had the tallest canopy, while Beauregard-14 and...
