Plant-parasitic nematodes pose a silent yet devastating threat to global agriculture, causing significant yield losses and economic damage. Traditional detection methods such as soil sampling, microscopy, and molecular diagnostics are slow, labor-intensive, and often ineffective in early-stage infestations. Nano biosensors: cuttingedge analytical tools that leverage nanomaterials like carbon nanotubes, graphene, and quantum dots to detect nematode-specific biochemical markers such as volatile organic compounds (VOCs) and oesophageal gland secretions, with unprecedented speed and accuracy. The real breakthrough lies in the fusion of artificial intelligence (AI) and nano-biosensor technology, forging a new frontier in precision agriculture. By integrating AI's powerful data analysis, pattern recognition, and predictive capabilities with the extraordinary sensitivity and specificity of nano-biosensors, it becomes possible to detect biomolecular changes in real-time, even at the earliest stages of disease progression. AI-driven nano biosensors can analyze real-time data, enhance detection precision, and provide actionable insights for farmers, enabling proactive and targeted pest management. This synergy revolutionizes nematode monitoring, paving the way for smarter, more sustainable agricultural practices. This review explores the transformative potential of AI-powered nano-biosensors in advancing precision agriculture. By integrating these technologies with smart farming systems, we move closer to real-time, costeffective, and field-deployable solutions, ushering in a new era of high-tech, eco-friendly crop protection.

Biodegradable mulch films are essential for reducing plastic pollution in agriculture; however, current production methods often rely on complex and costly chemical processes. This study presents an innovative, ecofriendly approach to developing fully biodegradable mulch films using untreated vegetable stalks and sodium alginate through a simple blending method. By eliminating the need for pretreatment, this process significantly reduces energy consumption and maximizes agricultural waste utilization. The optimized film formulation (30 % vegetable stalk, 3 % solution, 40 % glycerin) demonstrated excellent mechanical and barrier properties, including tensile strength (6.8 MPa), elongation at break (29 %), water vapor permeability (1.88 x 10-12 g & sdot;cm-1 & sdot;Pa-1 & sdot;s-1), and UV-blocking efficiency (98.5 %), and thermal insulation and moisture retention properties. Rheological analysis showed that the addition of vegetable stalks impacted the film-forming solution's properties, enhancing processing and application performance. Additionally, the films facilitated seed germination and maintained functionality on the surface of moist soil, while rapidly degrading when buried in moist soil. Life Cycle Assessment confirmed that the biodegradable films significantly reduce environmental impacts, supporting their potential for widespread adoption in sustainable agricultural practices. This study provides a scalable and cost-effective strategy for converting agricultural residues into high-performance biodegradable films, addressing the need for sustainable solutions in agriculture and environmental protection.

Arbuscular mycorrhizal (AM) fungi are important plant symbionts that provide plants with nutrients and water as well as support plant defences against pests and disease. Consequently, they present a promising alternative to using environmentally damaging and costly fertilisers and pesticides in agricultural systems. However, our limited understanding of how agricultural practices impact AM fungal diversity and functions is a key impediment to using them effectively in agriculture. We assessed how organic and conventional agricultural management systems shaped AM fungal communities. We also investigated how AM fungal communities derived from these agricultural management systems affected crop biomass and development. Six soil samples from five organically and five conventionally managed agricultural sites were used to cultivate Sorghum bicolor. Plant growth, plant nutrient concentrations and AM fungal colonisation rates were analysed alongside DNA metabarcoding of community composition. We observed that soil from conventional agricultural fields resulted in a pronounced reduction in sorghum biomass (-53.6%) and a significant delay in flowering compared to plants grown without AM fungi. Sorghum biomass was also reduced with soil from the organic system, but to a lesser extent (-30%) and without a delay in flowering. Organic systems were associated with a large proportion of AM fungal taxa (50.5% of VTs) not found in conventional systems, including Diversispora (r(2) = 0.09, p < 0.001), Archaeospora (r(2) = 0.07, p < 0.001) and Glomus (r(2) = 0.25, p < 0.001) spp., but also shared a large proportion of taxa with conventional systems (42.3% of VTs). Conventional systems had relatively few unique taxa (7.2% of VTs). Our results suggest that conventional agricultural practices selected against AM fungi that were, in this context, more beneficial for host plants. In contrast, organic management practices mitigate this negative effect, likely due to the presence of specific key AM fungal taxa. However, this mitigation is only partial, as less beneficial AM fungal taxa still persist, probably due to abiotic factors associated with agricultural management and the sensitivity of AM fungi to these factors. This persistence explains why the effect is not entirely eradicated. Read the free Plain Language Summary for this article on the Journal blog.

The study explored the long-term efficiency of an integrated electrodialysis-forward osmosis (EDFO) treatment technology for nutrient recovery and its application in irrigating and fertilizing high-value crops. Results showed a stable energy profile with consistent electrical conductivity (EC) trends in both municipal and dairy digestates, highlighting the system's capacity to maintain ionic stability, essential for long-term operation. Fouling resistance was indicated by gradual and minimal declines in current density, reflecting stable performance after three cycles and reducing the need for chemical cleaning. A greenhouse trial assessed the impact of using treated and untreated wastewater for irrigation on plant growth and nutrient dynamics in southern highbush blueberry (Vaccinium corymbosum L. interspecific hybrid). The plants were grown in a soilless potting media and irrigated with a modified Hoagland nutrient solution (control), untreated municipal or dairy digestate, or recovered nutrient water from municipal or dairy digestate treated by the EDFO process. Leaf area and shoot biomass were similar among the treatments, confirming that wastewater irrigation did not adversely affect blueberry growth. Furthermore, pH levels in the potting media were near or within the optimal range for blueberry cultivation (4.5-5.5), while EC exceeded salinity thresholds for the crop (> 2 dS m(-1)) but did not visibly damage the plants, suggesting that salt levels were manageable with periodic freshwater flushing. Mass-spectrometry-based, non-targeted analysis detected significant reductions in organic pollutants across treatment cycles. In particular, pharmaceuticals and pesticides in untreated digestate were reduced by over 90 % post-treatment, affirming the system's efficacy in removing emerging contaminants that could pose risks in agriculture and consumers. Given the favorable nutrient recovery and contaminant removal, the EDFO system offers a sustainable solution for wastewater reuse, enabling nutrient cycling in agricultural systems and reducing freshwater dependence.

Zinc (Zn) is a vital micronutrient required for optimal plant growth and soil fertility. Its use in the form of nanoparticles (NPs) has gained significant attention in agricultural applications. Green synthesized Zn-based NPs offer an eco-friendly solution to several conventional problems in agriculture. Several plants, bacteria, fungi and yeast have shown significant potential in fabricating Zn NPs that can provide environmentally friendly solutions in agriculture and the approach is aligned with sustainable agricultural practices, reducing the dependency on harmful agrochemicals. Zn-based NPs act as plant growth promoters, enhance crop yield, promote resilience to abiotic stressors and are efficient crop protection agents. Their role as a smart delivery system, enabling targeted and controlled release of agrochemicals, further signifies their potential use in agriculture. Because agriculture requires repeated applications hence, the toxicological aspects of Zn NPs cannot be ignored. Zn NPs are reported to cause phytotoxicity, including root damage, physiological and biochemical disturbances, and genotoxic effects. Furthermore, exposure to Zn NPs poses risks to soil microbiota, and aquatic and terrestrial organisms potentially impacting the ecosystem. The green synthesis of Zn-based NPs has a promising aspect for advancing sustainable agriculture by reducing agrochemical use and improving crop productivity. Their diverse applications as plant growth promoters, crop protectants and smart delivery systems emphasize their potential. However, the toxicological aspects are essential to ensure the standardization of doses for their safe and effective use. Further research would help address such concerns and help in developing viable and eco-friendly solutions for modern agriculture. (c) 2025 Society of Chemical Industry.

Agriculture is crucial for food security and safety, but agrochemical insufficiency in managing pest infestations leads to agrochemical overuse, reducing crop yields, escalating disease outbreaks, and dispersing resistant organisms. The Green Revolution led to inconsiderate usage of chemical synthetic pesticides and fertilizers resulting in low soil biodiversity and resistance to pests and pathogens. New research focuses on integrating pest-resistant genetically modified crops, climate-adaptive practices, and nano-pesticides, aiming to minimize pesticide usage and reduce harmful environmental impact. Nanotechnology offers a transformative potential for sustainable agriculture by enhancing pesticide delivery, precision farming, and crop productivity with negligible environmental impact. This technology offers the potential for developing environment-friendly, biocompatible, and intelligent insecticides that respond to ecological changes. Nanoparticles also supply materials to plants and generate sophisticated biosensors for precision farming. Conventional herbicides, insecticides, and fertilizers have been nanoencapsulated to aid in the gradual and continuous release of nutrients and agrochemicals. The targeted nanocarrier systems improve pesticide delivery, reducing environmental impact and pesticide resistance while ensuring minimal harm to the non-target organisms. Studies show nanoparticles like silver, zinc oxide, and silica as effective biocides, enhancing crop resilience and productivity. Nanotechnology has prospective in agriculture as a green and effective substitute, reducing environmental damage and improving pest control techniques. The related difficulties of nanotechnology in agriculture are also highlighted in this review, focusing on how it might help meet the demands of future food security and promote environment-friendly farming methods. The present review explores the application of nanotechnology in agriculture mainly focusing on precision farming and sustainable crop production. It also highlights its ability to enhance crop productivity, manage insect's population, improve soil health, and address environmental issues. However, limitations include its high manufacturing costs, regulatory deficiencies, and limited field-scale uses.

Microplastic pollution from the agriculture industry presents a growing environmental and public health concern, driven in part by the widespread use of poly(ethylene) (PE)-based mulch. While plastic mulch is essential for sustaining an increasing global population, its contribution to microplastic pollution necessitates alternative solutions. This work addresses the urgent need for biodegradable mulches (BDMs) that match the performance of traditional PE films. A comprehensive methodology is proposed for the development and characterization of novel BDM formulations, informed by scientific literature, regulatory guidelines, commercial practices, and industry standards. The proposed approach emphasizes scalable formulation and processing of biodegradable polymer feedstocks, avoiding toxic solvents through thermal blending. For laboratory-scale production, hot melt pressing and blow film molding techniques are highlighted for their ability to produce uniform and reproducible films. Uniaxial mechanical testing of dog bone-shaped samples is recommended for rapid performance screening against industry benchmarks while film stability, water absorption, and biodegradation are evaluated under simulated agricultural conditions. Analytical techniques such as thermogravimetric analysis and differential scanning calorimetry are employed to characterize key properties, ensuring that the developed BDMs align with practical and environmental demands.

Worldwide fruit crop yield is seriously threatened by drought stress; hence novel approaches to improve drought tolerance must be investigated. In this context, nano-selenium (Se) has come to light as a promising contender, exhibiting a variety of functions in reducing the negative consequences of drought stress. This review aims to summarize the present knowledge on the functioning of nano-Se in improving fruit crops' resistance to drought stress. In terms of physiology, there are evidence that nano-Se enhances water consumption efficiency and controls stomatal conductance to help maintain cellular water balance and improves photosynthetic efficiency by preventing oxidative damage and maintaining chlorophyll concentration during droughts. By scavenging reactive oxygen species (ROS) and regulating the activities of antioxidant enzymes, nano-Se functions as an effective antioxidant at the biochemical level, avoiding cellular damage and preserving redox homeostasis. Therefore, this review examines the role of nano-Se in accumulation of osmolytes, such as soluble sugars and proline, which helps with osmotic adjustment and cellular osmo-protection against dehydration caused by drought. Additionally, the review examines notable interactions of nano-Se with soil properties, impacting microbial populations, soil water retention capacity, and nutrient availability, hence mitigating the negative impacts of drought stress on plant growth and development. By improving the quality, yields and market ability of fruit crops, nano-Se holds potential as a tool for enhancing agricultural sustainability, particularly under stress conditions, but its widespread application requires careful evaluation of environmental risks, long-term effects, and economic viability. The current review summarizes its diverse functions at the physiological, biochemical, and soil levels highlighting how important it is for water-limited, sustainable agriculture.

Rice (Oryza sativa L.), a primary food source for a substantial portion of the world's population, faces a serious threat from bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae (Xoo), leading to considerable yield reductions. The excessive use of synthetic pesticides not only affects soil health but also disrupts the community of organisms living in the soil. While some pesticides degrade quickly, others persist, leading to long-term environmental damage. To address these challenges, the aqueous extract of Terminalia arjuna (T. arjuna), was investigated as a sustainable alternative for controlling Xoo. The extract was prepared using a Soxhlet apparatus, and its antibacterial activity was assessed via zone of inhibition assays and bacterial growth inhibition studies. The results revealed significant antibacterial activity, with inhibition zones of 9.1 +/- 0.76 mm at 25 mu g/ml, 14.16 +/- 1.04 mm at 50 mu g/ml, and 15.5 +/- 1.31 mm at 100 mu g/ml. Furthermore, the antibacterial mechanism of the T. arjuna extract was investigated using computational approaches. For this molecular docking of CbsA, LipA, T3SEs, PDF, and Ddl was conducted with the phytochemicals of T. arjuna. Further molecular dynamics simulation analysis shows that 3-Hydroxyspirost-8-en-11-one can inhibit Ddl and CbsA, while 9-Oximino-2,7-diethoxyfluorene and 2-Naphthalene methanol can interact with T3SEs and PDF, respectively resulting inhibition of growth of Xoo. These findings highlight T. arjuna's potential as an eco-friendly, natural pesticide to combat Xoo, offering a sustainable solution to reduce the reliance on synthetic pesticides and their detrimental environmental impact. Further field studies are needed to confirm these results.
