The present work concerns the biosynthesis of zinc oxide nanoparticles (ZnO NPs) using aqueous leaf extract of <em>Secamone emetica</em> (Retz.) R. Br. ex Sm. and investigates their biological applications and photocatalytic activity. UV, FTIR (Fourier Transform Infrared Spectroscopy), XRD (X-ray diffraction) and SEM (Scanning Electron Microscopy) with EDX (Energy Dispersive X-ray) analysis were used for characterization of ZnO NPs. In UV analysis, the biosynthesized ZnO NPs demonstrated a peak at 354 nm. FTIR analysis revealed functional groups. The XRD study revealed the presence of hexagonal wurtzite structures consistent with JCPDS (Joint Committee on Powder Diffraction Standards) card no: 89–1397. SEM analysis confirmed the spherical morphology of ZnO NPs, and revealed their size to be 55.38 nm. ZnO NPs efficiently restricted the growth of Gram-negative bacteria (<em>Pseudomonas aureginosa</em>) than Gram-positive bacteria. In DPPH (2,2-Diphenyl-1-picrylhydrazyl) assay, exhibited 48.3 % of inhibition, while in ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)) assay, was observed 72.65 % of inhibition. The larvicidal efficacy of ZnO NPs was tested against the 4^th instar larvae of <em>Aedes aegypti</em> and <em>Culex quinquefasciatus</em>. ZnO NPs showed considerable larval mortality against <em>Culex quinquefasciatus</em> (100 %) and <em>Aedes aegypti</em> (93.33 %). The photo-catalytic performance of ZnO NPs was tested for the degradation of methylene blue under direct sunlight exposure. Around 69.76 % of the dye was degraded after 210 min of exposure to sunlight. Therefore, the above results suggest that the biosynthesized ZnO NPs using the eco-friendly method can be applied for a diverse range of biological and environmental applications.</div></div>","PeriodicalId":100809,"journal":{"name":"Journal of Natural Pesticide Research","volume":"12 ","pages":"Article 100122"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143593214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Almond hulls are rich in crude protein and dietary fibre, making them a valuable livestock feed option. Unfortunately, the pesticides used in Almond production can be a limitation when using these hull as feed for dairy and beef cows, due to the potential for pesticide residues enter the food chain and emerge in dairy and beef products. This study suggests an alternative Systematic Approach Model to pathogen could help reduce chemical residues in Almond production. This approach involves a three-step process based on sustainable and less harmful substances to provide effective pathogen control. First, caffeine is used for its pest-repellent and insecticidal properties, which is followed by a silicon formulation to strengthen the bark and cuticle layers of the almond trees to provide natural physical barriers to pathogens. Finally, applying Vitamins B, C, and E will increase the tree’s internal immunity, improving its natural resistance to pathogens.

The primary objectives of this study were to evaluate the nematicidal activity of 167 <em>Trichoderma</em> isolates against <em>M. incognita</em> second-stage juveniles (J2) under in vitro conditions, assess the most potent species in greenhouse conditions for their ability to suppress root galling and nematode population, and determine the impact of these species on tomato plant growth parameters.
