Isolation and identification of Bacillus subtilis strain L249 and its control effect on tobacco brown spot disease in pot experiments
In recent years, the bacterial blight of cassava has caused substantial economic losses to the Chinese cassava industry. Chemical control methods have become the primary approach to control this disease; however, their widespread usage and harmful residues have raised concerns about environmental pollution. In order to avoid this, it is urgent to seek a green ecological method to prevent and control it. Biological control through the utilization of microorganisms not only effectively inhibits the disease, but also gives consideration to environmental friendliness. Therefore, investigating a
Variations of bacterial community diversity and structure of cigar tobacco during industrial fermentation
Leaf microorganism communities play significant roles in the process of plant growth, but the microbiome profiling of crop leaves is still a relatively new research area. Here, we used 16S rDNA sequencing to profile the microbiomes of 78 primary dried tobacco leaf samples from 26 locations in eight Chinese provinces. Our analyses revealed that the national leaf microbial communities contain 4473 operational taxonomic units (OTU) representing 1234 species, but there is a small, national core microbiome with only 14 OTU representing nine species. The function of this core microbiome is relate
Ovicidal effect of the hydro-methanolic and aqueous extract of Saponaria officinalis on Enterobius vermicularis eggs: an in vitro study
Enterobiasis is a gastrointestinal helminthic infection caused by Enterobius vermicularis. An adult human is less susceptible to infection than children. The present study was conducted at the laboratories of Parasitology, Faculty of Natural Sciences and life, University of Setif during the year 2023 to indicate the effect of aqueous and hydro-methanolic extracts of Saponaria officinalis in inhibited hatching and mortality of Enterobius vermicularis eggs in vitro. The efficacy of four extract concentrations (25, 50, 75 and 100 mg/ml) within 6 -48 hours were tested through egg hatch assay and l
Effect Of The Combination, Rate And Frequency Of Irrigation On The Production Performance Of Green Bean (Phaseolus vulgaris L) Under Controlled Conditions
Water is becoming increasingly scarce, creating more severe water stress due to climate change, particularly in the Mediterranean region. As a result, water supply is a major constraint to agricultural production in Algeria. On this basis, an experiment was carried out at the Mostaganem School of Agronomy under controlled conditions during the 2021/2022 cropping season. The aim was to study the effect of three irrigation rates (100%, 80%, and 60% FC) combined with 4 frequencies (each day, after 3 days, after 5 days, and after 7 days) on the production performance of the green bean crop (Phaseo

Evaluation of insecticidal activity of Nerium oleander and Salvia officinalis leaves extracts against Drosophila melanogaster (Diptera: Drosophilidae)
Plants are a promising source of bioactive secondary metabolites that could form an alternative to the indiscriminate use of chemical pesticides. Therefore, this study aimed to assess the effect of two aqueous extracts obtained from the leaves of Nerium oleander and Salvia officinalis by maceration method on Drosophila melanogaster Meigen, 1830 (Diptera : Drosophilidae) as biological model. Bio efficacy of extracts was evaluated through different doses (0.5, 1, 5, 10 and 20 μg/larva) by topical application, on the third instar larvae (12 h before pupariation) and the cumulative mortality of i
Geometric Approach to Achieving Uniform Surfaces on Fresh Phoby Using The Extrusion Method
Fresh Pho is a traditional dish in Vietnamese cuisine that is enjoyed by many different cultures all over the world. One of the most important quality characteristics of Fresh Pho is uniform surface, which closely related to the extrusion process. This article studies a geometric solution for achieving a uniform surface on Fresh Pho by using the extrusion method. In this research, the mold shape was designed, simulated and tested to find the shape that achieves equal velocity of noodles at the outlet of the mold, hence the quality of fresh rice noodles will be better. We designed and simulated
Study of the physico-chemical and bacteriological quality of surface water: the case of the Zit-Emba dam (Northeast of the Algeria)
In Algeria, the quality of surface water is in an advanced state of deterioration in vitally important basins, mainly because of discharges of urban and industrial waste. Reservoirs are silting up and losing useful capacity, and the discharge of silt into watercourses into watercourses poses enormous ecological and environmental problems. The objective of this study was to evaluate the physico-chemical and bacteriological quality of water, collected from Oued El-Hammam, the Zit-Emba dam basin, and the city of Skikda's drinking water supply. Physico-chemical and bacteriological analyses were ca
STRENGTH AND CRACK RESISTANCE OF LONG CYLINDRICAL SHELLS MADE OF REINFORCED CONCRETE AND FIBER-REINFORCED CONCRETE
The methodology of experimental research of long cylindrical shells to determine their stress-strain state, carrying capacity and crack resistance is proposed. To implement the task, the authors have developed a special stand. Eight cylindrical shell models were made for testing - four of reinforced concrete and four of fiber concrete. Fibro-concrete specimens-shells had additional dispersed reinforcement by steel fiber with bent ends in an amount of 1% by volume of concrete. All specimens-shells had a constant length and cross-sectional radius, and varied the thickness of the shell and the si
Composition and diversity of phyllospheric microbial community in tobacco leaves infected by tobacco target spot disease
Blister blight (BB) disease is caused by the obligate biotrophic fungal pathogen Exobasidium vexans Massee and seriously affects the yield and quality of Camellia sinensis. The use of chemical pesticides on tea leaves substantially increases the toxic risks of tea consumption. Botanic fungicide isobavachalcone (IBC) has the potential to control fungal diseases on many crops but has not been used on tea plants. In this study, the field control effects of IBC were evaluated by comparison and in combination with natural elicitor chitosan oligosaccharides (COSs) and the chemical pesticide pyrac
