For $h>0$, $\alpha\in [0,h)$ and $\mu\in {\mathbb R}$  denote by   $SD_h(\mu, \alpha)$ a class

of absolutely convergent in the half-plane $\Pi_0=\{s:\, \text{Re}\,s<0\}$ Dirichlet series

$F(s)=e^{sh}+\sum_{k=1}^{\infty}f_k\exp\{s\lambda_k\}$ such that

 

\smallskip\centerline{$\text{Re}\left\{\frac{(\mu-1)F'(s)-\mu F''(s)/h}{(\mu-1)F(s)-\mu F'(s)/h}\right\}>\alpha$ for all $s\in \Pi_0$,}

Authors: Sadik Dhuha Muhammed , Mohammed Ibrahim Hadi
Published: March 2024

Cladophora glomerata has numerous biologically active properties and is considered one of the most essential medicinal algae. The purpose of this research was to investigate the anticancer efficacy of Cladophora glomerata algae extract against human hepatocellular carcinoma (HepG2), human cervical carcinoma (HeLa), and normal mouse embryonic fibroblast (MEF) cell lines. The needed algae was found in the Hassan Al-Hamoud River , Baquba, Iraq. The chemical detection of some chemical components of the ethanolic extract of C. glomerata revealed that the extract contains a group of active compounds. The study showed significant variation (p<0.05) among inhibition percentages of cancer cell line HepG2, Hella, and MEF cell lines that were treated with different concentrations (15.1, 31.2, 62.5, 125, 250, 500, and 1000) μg/ml of C. glomerata extract. The outcomes showed that increased inhibition percentages of the above cell line were associated with increased concentrations. The inhibition percentage of HepG2, Hella, and  MEF cell lines were  1.6 ± 30.88, 1.7 ± 14.10, and 1.2 ± 2.31 at concentration 15.1 (mg/ml), and was 3.8 ± 84.90, 3.6 ± 88.29, and 3.9 ± 23.2, respectively at concentration 1000 (mg/ml). The study concluded that the C. glomerata extract with different concentrations significantly inhibited cancer cell lines (HepG2 and Hela) and ME because they have antiproliferative and antioxidant activity against cancers. The extract's inhibitory impact begins at low doses and increases with increasing concentration. The study would be beneficial to use macroalgae as new and sustainable sources of bioactive compounds against cancer.

Published: March 2024

Various bacterial pathotypes remain a significant public health concern due to their pathogenicity and antimicrobial resistance. Moreover, the ability of bacteria to form biofilms can hinder host defense and antimicrobial eradication, leading to additional resistance. This study aimed to estimate the cinnamic acid's anti-biofilm activity against biofilms-producing bacteria. From October to November 2023, various clinical isolates were obtained from the Bacteriology Unit, Ramadi Teaching Hospital, Iraq. All isolates were identified using a conventional and automated VITEK-2 compact system. Based on the Clinical and Laboratory Standards Institute (CLSI) guidelines and the European Committee on Antimicrobial Susceptibility Testing (EUCAST), the Kirby- Bauer disk diffusion and AST were performed for antimicrobial susceptibility. Biofilm formation was estimated using a 96-well Enzyme-linked immunosorbent assay (ELISA) reader. Based on the antimicrobial susceptibility test,  all bacterial isolates showed antibiotic resistance, including Kleibsella  pneumonieae, Psuedomonas aeruginosa, Escherichia coli and Staphylococcus aureus. The data showed that MICs of cinnamic acid against bacteria were 125 μg /ml.The biofilms formed by all isolates exhibited strong strength (OD570 : 0.078-0.099). Cinnamic acid demonstrated significant inhibition of biofilm production in Multidrug resistance (MDR) bacteria (P-value = 0.0236). The results indicated that Cinnamic acid could be a promising anti-infective agent based on its ability to inhibit MDR-bacterial infections through biofilm formation.
Waste-liquors generated during Handmade paper manufacture from cow dung as a potential source of biofertilizer
Authors: Narayana Satya , Sathiasivan Kiruthika , Chauhan Sunita , Rajesh Mathur
Published: March 2024

In India, cow dung is widely utilized to create formulations that serve as effective plant growth enhancers with antimicrobial properties. The cow dung-derived handmade paper manufacturing process produces two waste-liquor streams, a Raw Liquor (RL) produced through the dewatering of the cow-dung slurry and a Black Liquor (BL) produced during the soda pulping of dewatered cow dung. The present  study explored the potential of these waste streams to be used as plant biofertilizers for germination and cultivation of Vigna radiata seeds (mung bean, IPM-02-03 variety). An in vitro assay for seed germination efficiency and a pot study for plant growth promotion (PGP) activity were used to assess this potential. The in vitro assay demonstrated that nutrient-rich RL, with its 100% seed germination efficiency (better than the 85.7% of tap water) was an effective biofertilizer for seed germination. In contrast, BL yielded poor seed germination efficiency. The pot study showed that water irrigation led to good seed germination, survival, plant rooting and shooting, but it was probably deprived of nutrients for inducing good grain yields. When water was replaced with RL, it was able to replicate the results, but with good grain yields. In contrast, BL produced poorer germination, seed survival and PGP results. The poor biofertilization efficiency of BL was most probably due to the nutrient losses and toxic chemicals produced in the harsh pulping process. The  results showed that RL, though considered a waste stream, is sufficiently nutrient-rich to act as an effective biofertilizer for germinating mung bean seeds and promoting plant growth and grain yields.

Authors: Meer Mohammad Suhail , Vijayaprabhakaran Krishnan , Velusamy Selva Ganapathy , Shanmugavel Raja , Kumar Machakalai Rajesh
Published: March 2024

Sivakasi, popularly known as "Little Japan," is a town in the southern region of Tamil Nadu. The study area has a semi-arid tropical monsoon climate. The inhabitants depend heavily on groundwater, which is used extensively for irrigation, drinking, and domestic. The present research aimed to evaluate groundwater quality in Sivakasi, focusing on fluoride levels and major ions, providing essential information on the non-carcinogenic risks posed to residents, particularly adults, and the suitability of water for both drinking and agriculture. Fluoride concentration and the most important cations and anions were analyzed in 32 groundwater samples. The major cations and anions present in field samples are in the order of abundance: Cl> SO4> HCO3> Na > Mg >Ca> K. For drinking purposes, groundwater quality varies from moderate to poor, and over 70% of groundwater tests are out of condition for agricultural water supply. Fluoride levels in the samples from the study area ranged from 0.00 to 2.60 mg/l, with an average value of 1.60 mg/l. The hazardous Quotient (HQ) value for infants ranged from 0.00 E+00 to 1.69 E+00, children from 0.00 E+00 to 1.80 E+00, and for adults from 0.00E+00 to 1.88E+00. Additionally, the adults were more susceptible to non-carcinogenic threats than infants and children. This study on groundwater quality in Sivakasi highlights risks to health from excessive fluoride levels, particularly for adults, making it important for disaster mitigation. Understanding the non-carcinogenic hazards of contaminated water can drive disaster preparedness actions and resource allocation, emphasizing the need for secure water sources and resilient water management methods in the semiarid region.

Published: March 2024

India is one of the world’s largest producers and exporters of cotton, the major raw material for the textile industry, employing more than 4.5 crore people in the country. The present study aimed to analyse the impact of adverse trade in Indian cotton sector on labor and household income by employing Social Analysis Matrix based multiplier model and partial equilibrium model. Indian textile sector has strong backward linkages with primary input multiplier and household income multiplier of 4.13 and 3.44, respectively and, thus transmitting external impacts to the labour and household income. The sector has a higher multiplier effect of 10.17 on production activities, of which the impact on the cotton sector is 0.126. Fall in export and domestic demand for clothing and apparel in addition to movement restrictions around the world during the period 2020-2021, disrupted cotton supply chain and consequent fall in demand and price of the commodity. Simulations for the increase in carry-over stock and reduction in domestic consumption and cotton exports revealed that limiting the commodity's production and supply would retain the market equilibrium and increase the domestic price to the advantage of the farmers. The study reveals that dynamics in the Indian cotton sector trade significantly impacted labour and household income. Appropriate planning for areas under cotton cultivation and alternate procurement mechanisms during emergency situations would stabilise the Indian cotton economy.

Published: March 2024

Cauvery Delta is the major rice-growing tract of Tamil Nadu. Continuous waterlogging is inevitable in the delta region due to unexpected heavy rain, leading to stunted crop growth and poor soil conditions. The present study aimed to alleviate the waterlogging-associated problems of stunted growth, crop nutrition deficiency, heavy algal growth and poor soil aeration issues in the heavy clayey soils of deltaic region of Tamil Nadu. Field experiments were laid out with the treatments viz., CuSO4,, (5kg/ha) (T1), Gypsum (500 kg/ha) (T2), Conoweeding+Alternate Wetting and Drying Irrigation(AWDI) (T3), microbial consortia (K and Zn solubilising Bacteria  500 ml/ha) (T4) control (T5) and combination of all (T6) except  CuSO4  along with control .  The results indicated that the T6 recorded higher plant height (110.2 cm), productive tillers/m2 of 332, filled grains of 118.3 and less chaffy grains of 20.3 nos, high nutrient status of 265 kg/ha of available N,35.4 kg/ha of available P,342 kg/ha of available K,  21.1meq/100 g of Ca,8.2 meq/100 g of Mg and root length and volume. The  algal population in terms of dry biomass was reduced to 3.1 (g/m2) from the control group of 11.2 (g/m2) at 15 days after imposing treatment. The per cent increase of 26.0 % grain yield was also recorded in the combination treatment over control. From the present research, combined application of gypsum @500 kg/ha  +Cono weeding twice +AWDI and microbial consortia of Zn and K solubilising bacteria @500ml/ha could be recommended for better soil environment and rice production in the delta region.

Published: March 2024

Microbial based therapeutics for cancer have gained a significant interest in recent decades. The present study relies on the synthesis, analysis, and conjugation of Salmonella Leucine-rich Proteins (SlrP) with mesoporous silica nanoparticles (MSNN) to evaluate their potential anticancer activity. The SlrP proteins were effectively produced and isolated from Salmonella enterica using Tryptic Soy Broth (TSB), and the subsequent SDS-PAGE analysis verified the presence of a band at around 72 KDa. The MSN synthesis yielded particles with an average diameter of 68.05±0.87 nm and a pore diameter of 7.1 nm.   In addition, we synthesized MSNMPA and then conjugated them with SlrP. Characterization studies confirmed the effective conjugation. The cytotoxicity evaluation conducted on HeLa cells revealed no substantial modification in cell viability upon treatment with MSN alone. Nevertheless, when MSNMPA/SlrP was done, it demonstrated significant cytotoxic properties, as evidenced by an IC50 value of 10 µg/mL. The results indicate that SlrP-conjugated MSN (MSNMPA/SlrP) could be utilized as promising nanocarriers for delivering anticancer proteins.

Evaluating genetic diversity simplifies the identification of superior genotypes, facilitating the development of high-yielding, resilient to climatic conditions and promoting effective crop improvement. The present study aimed to examine the divergence, correlation and path analysis across 55 okra (Abelmoschus esculentus (L.) germplasms for 17 traits during the summer season (March- July) of 2022. The experiment utilized randomized complete block design with three replications conducted in Phagwara, Punjab.  Analysis of variance suggested a sufficient amount of genetic variation was found among all genotypes. Using Mahalanobis D2 analysis, the samples were classified into seven clusters, the largest being cluster I, composing 34 germplasm. Only one germplasm was found in Clusters II, IV, V, VI, and VII. The inter-cluster distance was highest between clusters II and VII, whereas the intra-cluster distance was greatest in Cluster III. The number of fruits per plant had the highest percent contribution to the divergence, accounting for 49.63%. At both phenotypic and genotypic levels, there was a strong positive correlation (+) observed between fruit yield and various characteristics, including plant height, fruit length, number of fruits per plant, number of marketable fruits per plant, average fruit weight, and the number of pickings. Genotypic path analysis revealed that characteristics such as the first flowering node, days to first flowering, days to 50% flowering, plant height, inter-nodal length, number of nodes per plant, number of fruits per plant, marketable fruits per plant, and average fruit weight exhibited a positive and direct effect on fruit yield. When selecting this trait to improve yield in okra through breeding, it is essential to focus on specific characteristics that directly contribute to higher production. This research will help resilient okra varieties understand yield-influencing factors in Punjab environmental conditions.
Seasonal variation in contamination and browning of Acacia nilotica nodal explants in vitro
Authors: Narang Anita , Kaur Surinder , Shukla Anupama
Published: March 2024

Major problems encountered in establishing axenic cultures are contamination and browning of explants and media. Contamination is initiated in explants excised from soil-borne tissues or adult trees. Several sterilizing agents (Tween 20, chlorine water, silver nitrate, mercuric chloride, etc.) or a wash in antibiotic solution are recommended to reduce this. . Establishing in vitro cultures of Acacia nilotica old tree nodal explants was a serious problem. The present study was undertaken to create a suitable protocol for in vitro micropropagation of nodal explants of Acacia nilotica subsp. indica. Contamination was controlled by sterilizing the explants by washing in polysan (5%, v/v along with 500mg/l PVP), thorough washing under tap water, 70% alcohol treatment and 0.1% HgCl2 treatment. Plant tissues release phenolic substances through their cut ends, which turn the media dark brown and toxic. Addition of various antioxidants or/and transfer of explants to fresh medium twice or thrice, at a few days’ intervals may overcome the problem.  Collection of explants in antioxidant solution and a wash in antioxidant solution prior to inoculation was helpful in reducing the phenolic exudation in the present investigations.  The addition of antioxidant (citric acid) to the medium also checked browning to some extent. The rate of infection and browning of explants varied in different seasons, the maximum being during winters and the minimum during summers of 2019. This was inversely related to the morphogenic response of explants i.e. maximum caulogenesis occurred in vitro during July (6.3±1.4 shoots per explant). The in vitro raised shoots showed 100% rooting on 2mg/l IBA augmented Nitsch’s (N) medium.
Evaluation of few bioactive components of spice origin for their antimicrobial potential towards microbes commonly implicated in food spoilage and foodborne pathogenesis
Authors: Bhatia Mamta , Sharma Alka
Published: March 2024

Natural components isolated from spices are gaining the attention of food researchers to prevent the growth of microbes associated with food spoilage and foodborne pathogenesis to meet the ever-increasing consumers’ demand for safe and wholesome food free from harmful synthetic preservatives. In the present study, five bioactive components of spice origin, namely, allylisothiocyanate (AITC), cinnamic aldehyde (CIA), cuminic aldehyde (CUA), eugenol (EU), and menthol (MT) were evaluated for their antimicrobial potential towards six bacterial strains (Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Pseudomonas alcaligenes, Shigella sonnei, Staphylococcus aureus) and eleven fungal strains (Alternaria solani, Aspergillus niger, Botrytis cinerea, Cladosporium herbarum, Fusarium oxysporum, Geotrichum candidum, Penicillium citrinum, Penicillium expansum, Phoma exigua, Rhizopus arrhizus and Rhizopus stolonifer), by opting agar well diffusion assay, impregnated paper disc method and broth dilution technique. All these seventeen microbes pose deleterious effects on food and human health. Among the bioactive compounds, CIA and CUA turned out to be the most potent inhibitors of microorganisms, whereas MT was found to be the least effective. Lower concentrations of bioactive components, ranging from 1.95 µL/mL to 15.62 µL/mL, were needed to inhibit fungi, while higher concentrations ranging from 15.62 µL/mL to 1000 µL/mL were needed to inhibit bacterial strains. Among the bacterial strains tested, gram-negative bacteria were inhibited at higher component concentration levels (31.25 µL/mL-1000 µL/mL) compared to gram-positive bacteria. The present study updates the existing information on the antimicrobial potency of natural substances, paving the way to further research on establishing spice bioactive components as ‘natural additives’.

Published: March 2024

Wheat is considered one of the most essential crops for Egypt. Nevertheless, it is also one of its largest imports. Therefore, it is important to develop an accurate wheat suitability model to define the most suitable areas for its production. This study aimed to develop a parametric-based Analytical Hierarchy Process (AHP) using Geographic Information Systems (GIS) for land suitability evaluation of wheat in a selected area in El-Beheira governorate, Egypt. The climatic and land parameters influencing wheat production in the studied area were selected and rated according to the parametric method. These parameters included slope, texture, calcium carbonate, sum of basic cations, pH, organic matter, salinity, exchangeable sodium percentage and mean temp. of the growing cycle. The rated parameters were processed according to the AHP. The results were compared with Storie and the Square root methods and field observations. When validated using field observations, the developed method had a higher accuracy suitability evaluation for wheat cultivation in the studied area than the other two methods. According to the developed method, almost all of the studied areas could be classified as very suitable (S1) for wheat cultivation. On the other hand, the wheat suitability evaluation according to the other two methods indicated that most of the studied area could be classified as moderately suitable (S2) and marginally suitable (S3), which contradicted the field survey.

Authors: Guidetto Betiana Alejandra , Fonseca Sebastian , Abrate Alejandro Martin , Politi Maria Teresa
Published: March 2024

Introducción: Durante la pandemia por COVID-19, los pacientes con peor evolución presentaron deterioro clínico a los 7-10 días del inicio de síntomas, lo cual sugiere que la respuesta inflamatoria podría participar de la fisiopatogenia de la enfermedad. El objetivo de este estudio fue evaluar la asociación entre los valores de proteína C reactiva (PCr) en plasma al ingreso sanatorial en adultos con COVID-19 y el requerimiento de asistencia respiratoria mecánica (ARM) durante la internación.

Métodos: Cohorte retrospectiva, observacional, en un centro privado de la provincia de Buenos Aires. Se incluyeron a adultos internados con diagnóstico de COVID-19 por hisopado nasal, mediante real time transcription polymerasa chain reaction o antígeno. El desenlace primario fue la asociación entre valores altos de PCr en plasma al ingreso sanatorial (≥8 mg/L) y el requerimiento de ARM durante la internación.

Resultados: De los 1.242 pacientes enrolados, 19,4% requirieron ARM y 11,7% fallecieron durante la internación. La PCr de los pacientes que requirieron ARM fue mayor que la de los que no la requirieron (9,45 [5,20-18,70] mg/L vs 4,95 [1,80-10,70] mg/L; p < 0,01). La PCr analizada como variable continua (OR = 1,39; IC95% 1,21-1,60; p < 0,001) y como variable categórica (≥8 mg/L) (OR = 2,66; IC95% 2,19-3,78; p < 0,001) presentó una asociación significativa con el requerimiento de ARM durante la internación. Secundariamente, se encontró una asociación significativa entre PCr y mortalidad intrahospitalaria.

Conclusión: El valor de PCr en plasma al ingreso sanatorial podría predecir la evolución clínica en pacientes adultos internados por COVID-19.

Published: March 2024

Introducción: La sarcopenia aumenta el riesgo de caídas y fracturas, además de relacionarse con diversas enfermedades y aumento de la mortalidad. Distintos grupos de investigación proponen diferentes definiciones para el diagnóstico de sarcopenia, que incluyen la medición de la masa muscular por DEXA y la valoración de la fuerza de prensión palmar a través de un dinamómetro de mano. Sin embargo, estos 2 instrumentos no están habitualmente disponibles en los consultorios médicos. Objetivos: Determinar la utilidad diagnóstica de 2 pruebas de rendimiento físico: velocidad de marcha e incorporarse de una silla, como herramientas para la detección de pacientes con probable sarcopenia. Metodología: Se incluyeron 706 mujeres, entre 50 y 85 años, a las que se realizó las pruebas funcionales y DXA (n=376) para medir la masa muscular. Resultados: El 26,1% registró una velocidad de marcha disminuida mientras que el 55,3% presentó alteración en la realización de la prueba de incorporarse de una silla. La prevalencia de sarcopenia varió desde un 4,5% hasta un 35% según los criterios utilizados. Ambas pruebas presentaron un alto valor predictivo negativo (>70%) para el diagnóstico de sarcopenia, mientras que la prueba de incorporarse de una silla mostró además, una alta sensibilidad (> 66%) para dicho diagnóstico. Conclusión: La implementación en el consultorio de estas pruebas sencillas y sin costo, simplificaría la detección de pacientes con probable sarcopenia.
ScholarOne - Good Morning, Madison, Wisconsin: How the Media Highlights Black Women’s Othermothering Strategies in Support of Black Girls
Authors: Bafu Ruby
Published: March 2024

This study uses discourse analysis of news articles published in Madison
to examine media framings of Black girls and responses to their needs.
Media analysis suggests that Black women in Madison act as othermothers
to Black girls and play a key role in supporting Black girls in
education and in other aspects of their lives. However, local newspapers
give only a small amount of attention to Black women’s efforts to
support Black girls, so dominant local newspaper narratives about Black
girls remain rooted in negative stereotypes. I argue that educators and
researchers can model Black women’s behavior towards Black girls.

Published: March 2024

The aim of this study was to examine the possibility of restoring
voluntary attention through the experience of soft fascination with
nature considering the predictive role of nature relatedness (NR). The
within-subject design was used to in two alterable contexts: a virtual
experience of urban and nature. The Nature Relatedness Scale and series
of addition tasks within 100 after exposure to short videos depicting
nature vs urban was performed by a group of 99 persons aged 18 to 70.
The results show the importance of contact with nature for increasing
the counting speed irrespectively to the intensity of NR.
ScholarOne - The Role and Function of Recognition for Fanon's Conception of Freedom
Authors: Gregson William
Published: March 2024

Frantz Fanon is often seen as both a proponent and radical critic of the
politics of recognition. This article seeks to reconcile Fanon’s project
of freedom as both being foundationally concerned with establishing the
conditions for recognitive reciprocity and providing an alternative to
the recognition paradigm. While it is argued that misrecognition poses a
threat to freedom insofar as it consists in the objectification of an
otherwise free and self-conscious subject, Fanon nonetheless identifies
three freedom-disabling forms of recognition: i) recognition-seeking as
a form of bad faith, ii) essentialist recognition of group identity, and
iii) recognition as falsely equated with freedom itself. Ultimately,
Fanon avoids these obstacles by articulating freedom as
self-constitution, for which recognition is a necessary but insufficient
condition.
ScholarOne - Widening student participation in Australia: Technologies of government, numbers, and calculations
Authors: Xu Ren-Hao
Published: March 2024

This paper critically examines Australia’s Demand-Driven Funding System
and its impact on student participation in higher education. It explores
the shift from a centrally-controlled allocation of university places to
one where universities exercise autonomy and bear financial
responsibility. Employing Foucault’s governmental technology, the study
reveals how universities navigate this new funding model through
strategic calculation and risk management. Utilising semi-structured

In recent years, China’s education has developed rapidly, but inequality
still exists. In the Chinese context, educational technology and
educational inequality are often discussed and studied together. Through
literature review, this paper briefly summarizes the advantages and
problems that need to be solved in the process of bridging the education
gap of educational technology and puts forward the idea of promoting
strengths and avoiding weaknesses from micro, meso and macro levels.
Finally, it is concluded that using AI and other educational
technologies as tools and focusing on learners’ own knowledge, ability
and literacy is the key to alleviating educational inequality.
ScholarOne - How proactive personality moderates the impact of abusive supervision on job performance: explanations from the resource acquisition mechanism
Authors: Ye Cunjun , Dong Yisheng
Published: March 2024

Although many studies have investigated the moderating effect of
boundary conditions on the relationship between abusive supervision and
outcome variables, existing research findings indicate who copes
effectively with abusive supervision but they do not tell us what they
do that works. Using a sample of 305 supervisor-subordinate dyads in a
two-wave survey, this study adopted a hierarchical regression analysis
to test the hypotheses. The results show that proactive personality
negatively moderates the negative relationship between abusive
supervision and job performance. The moderating effect of proactive
personality between abusive supervision and job performance was mediated
by job crafting (within of workplace) and leisure activity (outside of
workplace). The study helps to understand the moderating mechanism of
boundary conditions in the relationship between abusive supervision and
job performance, also understand the diversity of transmission
mechanisms involved.

Efficacy of Lemongrass and Soursop Leaf Extracts for Controlling ArmywOrm (Spodoptera litura J.E. Smith) Infestation in Green Mustard Cultivation]. Employing vegetable insecticide as a primary measure for controlling armyworms (Spodoptera litura) represents an environmentally friendly strategy to enhance yield. This research, conducted between December and February 2021 at the Plant Protection Laboratory and Plant Protection Gauze House, Faculty of Agriculture, Bengkulu University, aimed to determine the effective concentration of vegetable insecticides for managing armyworms infestation in green mustard. A randomized complete design (CRD) with six treatments and five replications was employed for the efficacy test. The treatments comprised: control, lemongrass extract, soursop leaf extract, lemongrass and soursop leaves extracts in a 1:1 ratio, lemongrass and soursop leaves extracts in a 1:2 ratio, and lemongrass and soursop leaves extracts in a 2:1 ratio. The results demonstrated that both lemongrass and soursop leaf extracts, either individually or in combination, effectively controlled S. litura larvae. Notably, an 8% concentration of citronella extract exhibited the highest mortality rate at 60%, with soursop leaves achieving 53.3%. In combination extracts, lemongrass and soursop leaves extracts in 1:1 and 2:1 ratio resulted in a 43.4% larvae control, while the ratio of lemongrass 1:2 to soursop leaves achieved a 36.6% larvae control. Overall, the research underscores the potential of vegetable insecticides, specifically lemongrass and soursop leaf extracts, as viable components of integrated pest management strategies to maintain crop yield in green mustard cultivation.
