In-vitro Evaluation of Trichoderma Species and Some Selected Botanical Extracts against Alternaria helianthi (Hansf) Causing Alternaria Blight of Sunflower

This study investigates the in vitro efficacy of bioagents and selected botanicals in managing Alternaria helianthi, the pathogen responsible for Alternaria blight in sunflower (Helianthus annuus L.). Two bioagents, Trichoderma harzianum and Trichoderma viride, and six botanicals—Azadirachta indica (neem), Lantana camara (lantana), Curcuma longa (turmeric), Aloe barbadensis (aloe vera), Withania somnifera (ashwagandha), and Mentha spicata (pudina)—were evaluated using the dual culture and poison food technique, respectively. The results showed that T. harzianum exhibited the highest inhibition of mycelial growth at 76.32%, while neem extract was the most effective among botanicals, achieving a maximum inhibition of 75.03% at 15% concentration. These findings suggest the potential of bioagents and botanicals in eco-friendly management strategies for Alternaria blight in sunflower cultivation.

Eco-friendly synthesis of silver nanoparticles: Enhancing optimization reaction, characterization, and antimicrobial properties with Lantana camara from geothermal area

Green synthesis methods for producing silver nanoparticles (AgNPs) have garnered significant attention for their potential in medical applications. Despite the known potential of Lantana camara in AgNP synthesis, there is a lack of studies investigating its application when grown in extreme geothermal environments, which may influence the properties and efficacy of the synthesized nanoparticles. This research aimed to fabricate AgNPs utilizing aqueous extract from L. camara, a plant growing in an extreme geothermal manifestation area. Another aim of this study is to evaluate their antimicrobial activity. Qualitative and quantitative phytochemical analyses of the plant's leaves were also conducted. Reaction optimization was performed using response surface methodology (RSM), employing a central composite design (CCD) approach. The characterization of AgNPs involved UV–vis spectroscopy, FTIR, SEM-EDX, and PSA. The antimicrobial testing was conducted against Gram-positive bacterium (S. aureus), Gram-negative bacterium (E. coli), and the fungus (C. albicans). The phytochemicals analysis revealed that the L. camara leaf extract contains flavonoids, phenolics, saponins, tannins, and steroids, lacking alkaloids and terpenoids, with total phenolic and flavonoid contents of 11.94 mg (GAE/g) and 6.70 mg (QE/g), respectively. The AgNPs exhibited a spherical shape with a surface plasmon resonance (SPR) peak at a wavelength of 417 nm, and the smallest particle size measured was 44 nm. Based on FTIR analysis, AgNPs have functional groups such as OH, NH, CC, and CH that were identified as groups involved in the reduction of Ag+ to Ag0 during the green synthesis of AgNPs. The AgNPs demonstrated the lowest antifungal activity against C. albicans. In summary, the aqueous leaf extract of L. camara from geothermal manifestation areas can serve as a bioreductant for AgNPs, exhibiting higher antibacterial activity against Gram-positive bacteria compared to Gram-negative ones.

Synthesis of enzyme-enriched zinc oxide nanoparticles using Lantana camara L. fruit extract for detoxification of phenol and derivatives

In this study, we evaluated the potential of Lantana camara L. (L. camara L.) fruit extract as a biogenic mediator for the synthesis of enzyme-rich zinc oxide nanoparticles (EZnO) aimed at the detoxification of phenol and its derivatives. The protein extraction yielded a maximum concentration in the 80 % cut fraction, with a protein concentration of 0.96 μg/ml. The highest peroxidase enzyme activity was measured at 41 U/min at 80 % cut using a 250 μg protein concentration, while the highest polyphenol oxidase activity of 7.16 μg/ml was observed in the 40 % cut fraction. The synthesis of EZnO nanoparticles was confirmed through a visible color change and UV–visible spectroscopy with a distinctive absorbance peak at 307. 40 nm. X-ray diffraction (XRD) analysis at 2θ angle indicated the crystalline structure of the nanoparticles, with characteristic peaks corresponding to the planes of the ZnO crystal lattice. Fourier-transform infrared spectroscopy (FTIR) characterization revealed the embedding of the peroxidase enzyme within the nanoparticles, evidenced by absorbance peaks at 1708.62 cm−1 corresponding to amide I, 1604.48 cm−1 corresponding to amide II, and 1380 cm−1 corresponding to amide III. Similarly, the presence of polyphenol oxidase was indicated by absorbance peaks at 3185.83 cm−1 and 2981.41 cm−1. Transmission electron microscopy (TEM) analysis showed the nanoparticles exhibited polydispersity with a size range of 10–100 nm, with an agglomerated morphology, suggesting successful enzyme-nanoparticle hybridization. The histogram was constructed based on the counting of nanoparticles with size which showed highest number of nanoparticles were in the range of between 10 and 20 nm. The BET analysis showed a surface area of 225.1 m2/g. The EZnO nanoparticles demonstrated effective detoxification capabilities, achieving 86 % removal of synthetic phenol, 63 % removal of synthetic 2-chlorophenol, and 69 % removal of their mixture within 24 h. These findings highlights the potential of L. camara L. fruit extract and EZnO nanoparticles for application in the detoxification of hazardous pollutants, offering a sustainable and efficient approach to environmental remediation.

Green Synthesis and Characterization of Hydroxyapatite Nanorods with Enhanced Antibacterial and Anticancer Properties

This study reports the microwave synthesis of hydroxyapatite nanorods using Lantana camara L. flower extract (LCF-HA) and characterized by FTIR, XRD, TEM and SEM-EDX techniques. The extract coating on the hydroxyapatite nanorods improves the antibacterial efficacy against Gram-positive bacteria. The study also evaluates the mitochondrial membrane potential (MMP), generation of reactive oxygen species (ROS) and capacity to induce apoptosis of LCF-HA. It shows that LCF-HA efficiently inhibits the growth of osteosarcoma cells (MG-63) in a dose-dependent manner. The efficacy of LCF-HA in inducing apoptosis in osteosarcoma cells is established by dual acridine orange/ethidium bromide (AO/EB) fluorescence labelling. Additionally, LCF-HA induces an increase in reactive oxygen species (ROS) generation and a reduction in mitochondrial membrane potential (MMP) levels. The findings indicate that derived LCF-HA has significant anticancer efficacy by inducing apoptosis in osteosarcoma cells through enhanced ROS generation, suggesting that derived LCF-HA may serve as a promising therapeutic target for bone cancer cell lines. Furthermore, the study demostrates excellent compatibility with osteoblast cells, highlighting its potential for bone regeneration applications.

Investigating the sustainable energy generation potential of an invasive weed: Lantana camara.

Lantana camara, one of the world's top ten most invasive species, was initially cultivated for ornamental use. However, it spread uncontrollably across the fallow areas and agricultural lands, threatening approximately 44% of Indian forests. Its invasion disrupts ecosystems by suppressing nearby plant growth through allelopathy and poses toxicity risks to grazing ruminants. It significantly increases forest fire risk by adding large amounts of combustible biomass, particularly dried L. camara. Despite efforts to control it using mechanical, chemical, and biocontrol methods, the results have been largely unsatisfactory, with associated costs estimated at $18,000 per square kilometre. Considering these challenges, recent research explored the potential of L. camara as a bioenergy resource. TheL. camarabriquettes exhibit a heating value of approximately 20MJ/kg with a low sulphur (0.5%), nitrogen (1%), and ash content (2%), making them suitable for decentralised energy production. Furthermore, bioethanol production fromL. camarahydrolysate has shown promising results, yielding 0.33g/g withPichia stipitisand0.47g/g with Saccharomyces cerevisiae, which is comparable to other lignocellulosic feedstocks. Additionally, the gasification of L. camara using a downdraft gasifier produced syngas with a lower heating value (LHV) of 6.4MJ/Nm3. These findings demonstrate that using L. camara for bioenergy production presents a dual solution, addressing the growing demand for renewable energy and managing invasive species. This review aims to critically evaluate the potential and challenges associated with the different energy production pathways for L. camara, highlighting its role in sustainable energy generation.

Thermal modification of Lantana camara stalks and its characterization

Abstract This paper deals with value addition and utilization of Lantana camara, an invasive species with unprecedented rate of growth, by thermal modification. Lantana camara stalks were thermally modified using vacuum heat treatment (VHT), oil heat treatment (OHT), and steam heat treatment (SHT) at 180 °C and 200 °C and subsequently changes in physical, chemical and mechanical properties were studied. Weight loss was observed in vacuum and steam heat treated samples due to thermal degradation while oil heat treated samples showed weight gain due to oil uptake. SHT exhibited the highest (19 %) weight loss at 200 °C. The color of the modified lantana attained uniform dark colour, OHT exhibited the most intense effect on colour changes. Fourier transform infrared (FTIR) and Fourier transform near infrared (FTNIR) spectroscopic analyses indicated degradation of hemicellulose and change in cellulose crystallinity due to heat treatment. Dimensional stability of thermally modified Lantana stalks improved across treatments, with SHT achieving the highest anti-swelling efficiency of 67.3 % at 200 °C and lowest water absorption (43 %) after 72 h of water soaking. The dynamic modulus of elasticity of thermally modified Lantana remained constant in all the treatment processes. Overall, the results indicate that thermal modification can increase utilization potential of L. camara.

Isolation and characterization of Streptococcus agalactiae inducing mass mortalities in cultured Nile tilapia (Oreochromis niloticus) with trials for disease control using zinc oxide nanoparticles and ethanolic leaf extracts of some medicinal plants

BackgroundStreptococcus agalactiae (Group B streptococcus, GBS) induces a serious infection that can harm not only aquatic life but also humans and other animals. In a fish farm in southern Egypt, Nile tilapia (Oreochromis niloticus) has developed an epidemic with clinical symptoms resembling piscine streptococcosis.ResultsInitial microscopic inspection of the affected fish brain and kidney indicated the presence of Gram-positive cocci. S. agalactiae was effectively isolated and identified using nucleotide homology of the 16S rRNA and species-specific PCR. The partial 16S rRNA sequence was deposited in the GenBank database at the NCBI and given the accession number MW599202. Genotyping using RAPD analysis indicated that the isolates in the present study belonged to the same genotypes and had the same origin. The challenge test, via immersion (9.2 × 107, 9.2 × 106, and 9.2 × 105 CFU/ml for 1 h) or intraperitoneal injection (4.6 × 107, 4.6 × 106, and 4.6 × 105 CFU/fish), elicited clinical symptoms resembling those of naturally infected fish with a mortality rate as high as 80%. The ability to create a biofilm as one of the pathogen virulence factors was verified. Zinc oxide nanoparticles and the ethanolic leaf extracts of nine medicinal plants demonstrated considerable antibacterial activities against the tested S. agalactiae strain with low minimum bactericidal concentrations (MBC) and minimum inhibitory concentrations (MIC). The ethanolic leaf extracts from Lantana camara and Aberia caffra showed potent antibacterial activity with MBC values of 0.24 and 0.485 mg/ml, and MIC values of 0.12 & 0.24 mg/ml, respectively.ConclusionThis study isolated S. agalactiae from O. niloticus mortalities in a fish farm in Assiut, Egypt. The pathogen persists in fish environments and can escape through biofilm formation, suggesting it cannot be easily eliminated. However, promising findings were obtained with in vitro control employing zinc oxide nanoparticles and medicinal plant extracts. Nevertheless further in vivo research is needed.

Comparative study of chemical constituents and biological potency in Lantana camara Linn. leaf essential oil collected from two different sites in Northeast India

The ubiquitous occurrence of Lantana camara highlights its exceptional ecological versatility. Leaves of L. camara were obtained for this study from two different locations of NE, India. Hydro distillation was used to extract the essential oils from the leaves, and gas chromatography-mass spectrometry (GC-MS) and gas chromatography-flame ionization detection (GC-FID) were used to study the chemical profiles of the isolated oils. The essential oil analysis detected 35 components in total essential oil from Location 1 (BLCEO) while in Location 2 essential oil (JLCEO), 29 components were identified. Caryophyllene, humulene and sabinene were present in considerably major amounts in both BLCEO and JLCEO, though variation in area percentage was seen. The anti-oxidant properties of BLCEO were better than that of JLCEO. The BLCEO has also exhibited better results in inhibiting acetylcholinesterase. However, both the essential oils did not show any prominent results in α-amylase inhibitory assay and anti-tyrosinase activity. In this study, the phytochemical composition and their effect on the bioactivity of both samples were observed. The chemical constitution of L. camara essential oils (LCEO) and its possible ecological ramifications have also been well explained.

New observations on prey scarab beetles and host plants of the green lynx spider, Peucetia viridans (Hentz, 1832) (Araneae: Oxyopidae) in Oaxaca, Mexico

ABSTRACT Peucetia viridans (Hentz), commonly called the lynx spider, is an important predator with a diet that encompasses a wide variety of insects and arachnids, including cannibalism. Although several studies that address aspects related to its ecology and behaviour have been carried out, there is a notable lack of studies focused on the recording of its prey and hosts. This information gap is particularly evident regarding the interaction of the spider with beetles belonging to the family Scarabaeidae. To contribute to the knowledge of the feeding habits and host preferences of P. viridans, observations were made in two localities of the Valles Centrales region of Oaxaca, Mexico. Lynx spiders were observed on Croton ciliatoglandulifer Ortega, Lantana camara Linnaeus, Solanum mitlense Dunal, and Wigandia urens (Ruiz and Pav.) Kunth. Spiders utilise these plants as shelter and to ambush their prey, thereby reducing herbivore populations and protecting the plants. In return, the plants provide the spiders with prey and floral and extrafloral nectaries as food sources. Therefore, spiders and plants have a facultative mutualistic relationship, whereas the relationship between spiders and herbivores is antagonistic. For the first time Diplotaxis trapezifera Bates, Macrodactylus fulvescens Bates, Paranomala discoidalis (Bates), Strigoderma costulipennis Bates, Strigoderma sulcipennis Burmeister, and Euphoria pulchella (Gory and Percheron) as prey, and Wigandia urens, Lantana camara and Solanum mitlense as host plants are recorded. A checklist of host plants for P. viridans is given. Overall, these new observations highlight the importance that tritrophic interactions (plant–herbivore–natural enemy) have in wild systems, which are essential for maintaining ecological balance.

Green Chemical Synthesis of Cube‐Shaped CuFe2O4 Nanoparticles for Use as Magnetically Retrievable Catalysts in A3 Coupling Reactions

ABSTRACTA3 coupling reaction is a multicomponent reaction (MCR) involving aryl aldehydes, phenyl acetylenes and amines to synthesize a variety of biologically active propargylamine derivatives. Herein, we report the preparation of cube‐shaped CuFe2O4 nanoparticles (NPs) via the hydrothermal method in the presence of Lantana camara flower (LCF) extract to use them as catalysts to synthesize propargylamine derivatives. X‐ray diffraction study confirms the formation of CuFe2O4 NPs with cubic spinel structures. In the presence of LCF extract, cube‐shaped CuFe2O4 NPs are formed predominantly irrespective of the type of alkali used as the hydrolyzing agent. However, a mixture of nearly spherical and cube‐shaped particles has been formed in the absence of additives. The synthesized CuFe2O4 NPs exhibit superparamagnetic behaviour and are magnetically ordered. The synthesized cube‐shaped CuFe2O4 NPs exhibit excellent catalytic activity in the A3 coupling reaction between benzaldehyde, piperidine and phenylacetylene to give propargylamine with a yield of 90% under the optimum conditions. The catalyst is highly stable and magnetically retrievable facilitating reusability for up to five cycles without considerable loss of catalytic activity. The protocol is suitable for the synthesis of a diverse range of propargylamine derivatives with moderate to excellent yield.

Efficacy of Botanical Insecticides for Controlling Cochineal Scale (Dactylopius opuntiae) Insect on Cactus (Dactylcompound sopius opuntiae) Plant at Southern Tigray, Ethiopia

Cochineal scale insects, scientifically known as D. opuntiae, are small insects that feed on the sap of cacti plants. These insects are notorious for their ability to rapidly reproduce and spread, causing significant damage to cactus populations. Tigray region, located in northern Ethiopia, has been particularly affected by the relentless attack of cochineal scale insects on its cacti. The aim of this study was to evaluate botanical insecticide to control cochineal scale insect of cacti plant in southern Tigray, Ethiopia. Field experiment was conducted during 2024 in off-season at Raya-azobo district. A total of five treatments; leave extract (Neem, Lantana camara and Pepper tree and liquid soap), salt+liquid soup, liquid soup, water and control (no sprayed)) were used in the field experiment. The experiment was laid out randomized complete block design (RCBD) with three replications. The mortality rate of cochineal scale insect had a significant difference at (p<0.001) among the treatments. The highest rate of mortality (free of cochineal scale insect) was calculated from the leave extract (100%) extracted from leaves. However, the increasing number of cochineal scale insect was observed from untreated (control) (+9.9%) followed by cladodes treated with water (45.29%). The current research findings provide strong evidence that botanical insecticide derived from plant leaves could be an effective solution for controlling cochineal scale insect infestations on cacti. These eco-friendly alternatives offer several advantages over synthetic pesticides in terms of reduced toxicity to non-target organisms. Beside; it should be promoted to further demonstration and popularization at farmer level in the coming off-season.

Associations between Lantana camara L. (Verbenaceae) and common native species in an African savanna

Abstract Lantana camara L. (Verbenaceae) is recognised as a problematic invasive alien plant species in many parts of the world. To eradicate or control this global invader, we need to understand the drivers of its spread and impacts and the potential for native recovery after the invader has been removed. Here, we tested for species associations between L. camara and native plant species and large herbivores in Queen Elizabeth National Park, Uganda. We inventoried 40,100‐m2 nested plots spread over a 1 × 1‐km grid cell in the park's savanna landscape, with 11 plots located in uninvaded areas. Most of the plots (30 of 40) had been affected by fire. Lantana camara covered 29 (73%) plots, 11 (38%) of which were in open grassland. Of the large herbivores that frequented areas free of L. camara, the Ugandan kob Adenota kob thomasi Sclater tended to avoid the areas invaded. The floristic composition of invaded areas differed significantly from that of noninvaded areas, with several palatable species rare or absent from L. camara‐invaded areas. Practical implication: These observations indicate the presence of potential recovery constraints that will need to be overcome after L. camara has been removed. Sustained efforts will be needed to suppress the invader and subsequently enrich and bolster native recovery.

Impact of invasive alien plants on the resident floral diversity in Koshi Tappu Wildlife Reserve, Nepal.

Invasive alien plant species (IAPS) pose a serious threat to overall plant biodiversity across the globe. Nepal's national parks and protected areas are not devoid of the impact of IAPS. Unfortunately, there is a substantial gap in knowledge regarding the extent and impact of invasion in protected areas of Nepal. This study assessed the impact of invasive alien plant species on the resident plant species of the Koshi Tapu wildlife reserve. After a preliminary field observation, we selected five major IAPS in the area, Mesosphaerum suaveolens, Chromolaena odorata, Ipomoea carnea, Lantana camara, and Mikania micrantha for this study. Ten pairs of adjacent plots sized 4 m × 4 m were surveyed for each invasive species, comprising diverse vegetation types. Each pair consisted of one "invaded plot" where the invasive species was dominant with cover greater than 50%, and another "uninvaded plot" laid out in an adjacent area with similar site conditions but without the invasive species. We calculated the Sørensen Index of Similarity for each paired plot. Wilcoxon rank-sum test was employed to compare ecological parameters between invaded and uninvaded plots for various plant species. Similarly, the difference in impact between each of the five invasive species was assessed using the Kruskal-Wallis test. Species richness varied significantly between invaded and uninvaded plots for C. odorata and I. carnea. The most significant impact on species composition of invaded communities (39.6%) was observed for C. odorata. The cover of the other dominant species varied significantly between invaded and uninvaded plots for all five species studied. The Kruskal-Wallis test showed no significant difference in the impact caused by the five studied invasive species on Species richness, Shannon-Wiener diversity index, species evenness, and height of dominant species. However, a significant difference was observed between the impacts of five studied invasive species and the cover of other dominant species. The crown cover of dominant species decreased much more in the invaded plots of L. camara and M. micrantha than in other species. Specialized management efforts are required to control highly invasive species, such as C. odorata and I. carnea, alongside proactive measures to prevent further spread in ecologically sensitive areas.

Ethanolic and aqueous extracts of Lantana camara show antiepileptic and anxiolytic effects by inhibiting the ferroptosis pathway in kainate-treated mice

In Cameroon, epilepsy is one of the most common neurological diseases. Available anti-epileptic medication, on the other hand, have been associated with pharmacological toxicity and emotional impairment. The identification of a more efficient replacement is critical. Recent research reveals that ferroptosis contributes to the pathophysiology of epilepsy and related anxiety disorders. Lantana camara is a plant with a high neuropharmacological potential, but its mechanisms of action have yet to be understood. The purpose of this study was to determine the effect of ethanolic and aqueous extracts of Lantana camara on the kainate model of epilepsy in mice. The focus was on these extracts' capacity to suppress ferroptosis. Mice were injected with kainate (12 mg/kg, i.p.) to induce epilepsy. After status epilepticus, animals were left for 19 days, which correspond to an epileptogenic period. After the appearance of spontaneous recurrent seizures, mice were treated with distilled water (10 ml/kg, p.o.), levetiracetam (80 mg/kg, p.o.), sodium valproate (300 mg/kg, p.o.), ethanolic extract of L. camara (230, 460, 920 mg/kg, p.o.), or an aqueous extract of L. camara (460 mg/kg p.o.). These treatments lasted for 14 days. During this period, the number and duration of seizures were recorded. The mice were then subjected to elevated zero-maze and open field tests to assess anxiety-like behavior. At the end, mice were sacrificed and hippocampus, amygdala, and striatum were dissected out for biochemical and histological analyses. The extracts alleviated seizure- and anxiety-like behavior in KA-treated mice. Decreased iron levels, reflected by a decrease in ferritin levels and a increase in transferrin levels, were observed in the hippocampus, striatum and amygdala of the extract-treated group compared to the KA-treated group. In addition, increase in GABA and GSH levels, and a decrease in MDA levels were observed in these groups. Hematoxylin-eosin staining revealed less pronounced neuronal degeneration and a more sustained architecture in the brain region of extract-treated mice. These findings indicated that ethanolic and aqueous extracts of L. camara effectively attenuate seizures and anxiety disorders. Probable mechanisms of action include GABAergic, iron, GSH, and MDA modulations.

Occurrence of scarab species belonging to Cetoniinae and Sericinae (Coleoptera: Scarabaeidae) on <i>Lantana camara</i> L. in India

Lantana camara L. (Verbenaceae) is deemed as one of the world’s toughest weeds posing major threats to the biodiversity and ecosystem. Lantana has been subject to numerous biocontrol attempts in India and other parts of the world. A survey of the phytophagous scarab species associated with Lantana camara was undertaken in Shettihalli village of Karnataka, India during 2024. The study yielded one Sericinae species, Maladera mutabilis (Fabricius, 1775), and five Cetoniinae species, viz., Clinteria klugi (Hope, 1831), Anthracophora crucifera (Olivier, 1789), Protaetia aurichalcea (Fabricius, 1775), Gametis versicolor (Fabricius, 1775) and Tephraea cinerea (Kraatz, 1898). Two species, G. versicolor and C. klugi were found to be abundant and predominant in Lanatana ecosystem. Their potential as biocontrol agents of the weed need to be ascertained.

Miscellaneous prospects of invasive Lantana camara biomass-a standpoint on bioenergy generation and value addition.

Investigation of Lantana camara biomass for potential bioenergy generation integrates invasive species (IS) management with the unabated demand for bio-energy. In the present investigation, L. camara was used to produce bio-oil by thermochemical conversion (pyrolysis). The resultant product evinced energy yield of 62.58% with 64.95% of elemental carbon (C) content and endorsed the suitability of L. camara bio-oil for biofuel applications and value addition. Thermogravimetric (TG-DTG) analysis revealed a short thermal degradation profile, whereas spectroscopic analyses detected a host of organic compounds such as esters, phenols, ketones, aldehydes, aliphatics, and aromatics. The economic analysis of L. camara biomass conversion technology carried out in this study proved to be commercially competitive and viable versus petroleum refining. Antimicrobial and antioxidant assays with bio-oil evinced highest zone of inhibition (ZOI) against Candida albicans (31.02mm), and displayed strong antioxidant property (DPPH IC50 value 233.72 ± 0.2μg/ml). The bio-oil exhibited rheological characteristics of shear thinning and pseudoplastic fluid, particularly at low and intermediate shear rates. The present study highlights the multifaceted advantages of utilizing L. camara biomass, which include environmental remediation via waste management, bioenergy generation, and the feasibility of generating value-added products.

Anti-Phytomonas activity of the lyophilized residues obtained from the distillation of Lantana camara L. essential oil.

On an industrial scale, the residues accumulated in essential oil distilleries can be compared to the volume of residues produced in the textile industry. Although these residues are discarded, they possess molecules with diverse biological activities, including their application in phytopathogen control. In this study, the chemical profile of the residue from the hydrodistillation of Lantana camara L. leaves was determined using high-performance liquid chromatography (HPLC). Additionally, the effect of the residue on cells was assessed by determining plasma membrane integrity, levels of reactive oxygen species (ROS) production, and mitochondrial potential depolarization. The viability and cell density of Phytomonas serpens parasites significantly decreased after treatment with increasing concentrations of the lyophilized residue from accession LAC-038 (RL038). RL038 reduced cell viability by an average of 61.36%. ROS levels increased by approximately 2 × and 3 × at RL038 concentrations of 120 µg/mL and 180 µg/mL, respectively. It was observed that the same concentrations modified mitochondrial potential, reducing fluorescence by 44.6% and 46.8%, respectively. Analytical liquid chromatography of RL038 revealed the presence of 17 peaks subsequently classified as phenolic acids and flavonoids. RL038 from the hydrodistillation of Lantana camara L. leaves is a source of biologically active compounds with antiprotozoal potential.

Global invasion risk assessment of Lantana camara, a highly invasive weed, under future environmental change

Invasion risk assessments are essential for making informed decisions, allocating resources, and implementing targeted strategies to prevent or minimize the harmful effects of invasive species on native biodiversity, agricultural productivity, and natural ecosystems. In this study, the random forest algorithm was used to assess the spatial invasion risk of Lantana camara, one of the world’s top 100 worst invasive weeds, across all continents under current and future environmental conditions. The current invasion risk was relatively high on four continents (i.e., Africa, Australia, Oceania, and South America) within approximately 35°N and 35°S latitude, estimated to cover at least 68.98 % of the total land surface. Furthermore, projections for future environmental changes suggested a substantial increase in invasion risk across all continents, with the most significant changes (251.52 %) observed in Europe compared with current invasion levels. Additionally, invasion risk was predicted to extend beyond 35°N latitude. Categorizing 200 countries and territories into distinct risk levels, 27 countries had current invasion potential, and introduction and establishment was predicted in 114 countries. Moreover, at least 45 countries, including Canada, India, Italy, and United States, were projected to transition from no or low invasion risk to high invasion risk and 28 countries had a risk increase of over 50 %. Current study provides valuable insights into the global invasion risk posed by L. camara. These results are expected to be of great utility for invasive weed management, facilitating the development of control and sustainable management strategies for this notorious weed at both global and local scales.

SCREENING OF PESTICIDAL PROPERTIES OF LANTANA CAMARA AND CALOTROPIS PROCERA EXTRACT AND ITS APPLICATION AGAINST SPODOPTERA LITURA(TOBACCO CUT-WORM)

In recent years botanical extracts that appears to have a vital role in the Development of low cost pesticides together with for Agricultural and forestry crop yield enhancement. Further more for the safety of Environment and public health. The Detrimental Environmental implications of the Synthetic bio-pesticides have forced to search for some substitute methods. This lead to enhanced development of compounds based on the types of naturally occurring toxins of biological origin having a lot of biological activities. This includes plant extracts, which are now well known because they are environmentally harmless and host specific. The different concentrations of plant extracts with different solvents (polar, semi-polar and non-polar) were tested for mortality properties against Spodoptera liturathird instar larvae.
