Overused agrochemicals threaten the environment and human health. Nanotechnology has shown great potential for maintaining or minimizing environmental issues in agriculture . Herein, a polyethylene glycol-coated copper nanoclusters (PEG@Cu NCs) has been developed for efficient utilization by tobacco. The NCs showed the superior antifungal activity against Alternaria alternata , achieving comparable activity using a dose almost 35-fold lower than that of 46% copper hydroxide water power (WP). More importantly, PEG@Cu NCs exhibited excellent therapeutic potential via xylem delivery. In the meantime, promising bioavailability of the NCs was achieved, which could be absorbed by tobacco seedlings via roots and foliar tissues (epidermal and mesophyll cells). In addition, the biosafety of PEG@Cu NCs was investigated in tobacco and earthworms. Both root exposure (1.27–3.17 mg L −1 ) and leaf exposure (1.27–6.33 mg L −1 ) to PEG@Cu NCs had no negative effects on tobacco growth. The acute toxicity of PEG@Cu NCs to earthworms was low, as determined by the 7 day-LC 50 value of 46.253 mg kg −1 and 14 day-LC 50 value of 30.187 mg kg −1 . Overall, such NCs are expected to be a competitive alternative to Cu-based fungicides in sustainable agriculture due to their superior antifungal properties , excellent biocompatibility, and high efficiency bioavailability.

Gelsemium elegans Benth. ( Loganiaceae ), also known as heartbreak herb, can be used in the manufacture of herbal medicines. Insecticidal activity has also been found and can be used to develop botanical insecticides. This study aimed to reveal the insecticidal mechanism of its extracts against red fire ants and provide strategies for the development of biopesticides and the promotion of green and sustainable agriculture. 16s rRNA, pathohistological, behavioral, and enzyme activity assays were performed to reveal its biological effects, including the effects on non-target organisms. Our results showed that red fire ants exposed to G. elegans extracts exhibited slowed growth, reduced feeding, and decreased aggressiveness. The midgut and its peritrophic membrane of red fire ant were significantly disrupted, the diversity of gut microbial community was reduced, and the balance of microbial composition was disturbed. Significant increases in functional abundance of xenobiotics biodegradation and metabolism pathway and P450s enzyme activity confirmed the toxic stress of G. elegans extract. Functional prediction of Kyoto Encyclopedia of Genes and Genomes pathway showed that the functional abundance of novobiocin biosynthesis, flavonoid biosynthesis, lysosome, proteasome, and wingless/integrated signaling pathways were significantly inhibited in the gut. Besides, G. elegans extracts induced an increase in acetylcholinesterase activity. These results revealed dysregulation of immune system and metabolic functions in red fire ants, as well as toxic effects of G. elegans extracts on physiological functions and nerves. These findings revealed the insecticidal mechanism of G. elegans and supported the development of eco-friendly insecticides for red fire ants.

Various strategies have been developed to improve the applicability of hydrophobic pesticides for better effectiveness in agriculture. However, existing formulations of hydrophobic pesticides still suffer from complicated processing, abused organic solvents, indispensable surfactants, or inescapable ecotoxicity, which strictly limit their applications. Herein, a dynamic covalent bond tailored pesticide (fipronil) amphiphile is constructed to address the above issues, which accomplishes the nanodispersion, full wetting, and precise delivery without organic solvents, surfactants, and materials simultaneously. By introducing a hydrophilic ligand on the hydrophobic fipronil through an imine bond, the cleavable fipronil amphiphile (FPP) exhibits superior water solubility and can even self-assemble into micelles at higher concentrations, which can be directly applied in powder form without organic solvents. Attributed to the suitable hydrophilic/hydrophobic ratio, FPP achieves full wetting and effective deposition on superhydrophobic rice leaves without surfactants. Moreover, benefiting from the unique dynamic nature of the imine bond, FPP maintains good storage stability while sensitively releasing back to fipronil under the humidity and pH trigger, consequently implementing the precise delivery for nontarget Apis cerana and target Chilo suppressalis without materials. To our knowledge, this dynamic covalent bond tailored amphiphile strategy is the first idea that simultaneously takes the dispersibility, wettability, and responsiveness of hydrophobic pesticides into account, providing a possibility to control the entire journey of field application and even promising to be incorporated into the synthesis process, thus paving the way for modern sustainable agriculture.

Fungal diseases caused by Botrytis cinerea and insect infestations by aphids often occur simultaneously during plant growth. A co-delivery nanosystem for dual-pesticide may enhance pesticide efficiency and reduce the required dosage of pesticides through synergistic effects. Therefore, in this study, we developed a dual pH-responsive nanocomposite AZOX/Thi@BMMs@MIL-88B (ATBM) based on bimodal mesoporous silica (BMMs) and metal organic framework MIL-88B, which was loaded with fungicide azoxystrobin (AZOX) and insecticide thiamethoxam (Thi) to control grey mould and aphid pests. The loading capacities of the two pesticides in the nanocomposite were 18.56 % (AZOX) and 37.38 % (Thi). The nanoparticles (NPs) were spindle-shaped with a hydrated particle size of 771.60 ± 12.55 nm and possessed excellent pH-responsive controlled release behavior. The NPs also demonstrated good wettability and stability due to the entrapment of nanocarriers. Fluorescence tracking experiments verified that the NPs could be effectively absorbed and translocated by pathogenic fungal mycelium and pea seedlings. The bioactivities of ATBM against B. cinerea and A. pisum increased by 9.58 % (AZOX) and 39.48 % (Thi), respectively, compared to the commercialized technical control (TC). This nanocomplex promoted the growth of pea seedlings through the introduction of iron ions and by activating the oxidative stress system, and the excellent biosafety of NPs could minimize environmental risk. In summary, this hybrid bi-carrier dual-pesticide nanopesticide-fertilizer showed significant promise for application in sustainable agriculture.

Microalgae cultivation in hydrogels offers a promising solution to address water and arable land scarcity for enhanced agriculture efficiency and food production. However, such emerging culture system is often associated with tedious hydrogel dissolution and complex nutrient extraction, which limit the potential of microalgae as sustainable food resources. Herein, we develop a microalgae-laden polysaccharide-based hydrogels (MPHs), which can directly serve as easy-to-swallow nutritional alternative foods after cultivation without post-treatment. Specifically, microalgae are formulated with starch and carrageenan for MPHs, and the construction of living microalgal frameworks with customizable architectures enhances the light and water utilization, exhibiting significantly increased microalgal yield (9.1 ± 0.3 g L −1 ), 4.3 times higher than that of conventional liquid systems. Moreover, the MPH scaffold can be designed into various structures and shows high content of protein after cultivation, therefore emerging as easy-to-swallow foods for people with dysphagia. International Initiative for the Standardization of Dysphagia Diet (IDDSI) evaluation further confirms the hydrogel-like behavior aligned with IDDSI levels 5–7, highlighting its potential as structured alternative foods. This streamlined microalgae farming not only improves the efficiency of biosynthesis, but also democratizes access to nutritional food alternatives for food sustainability.

The persistent threat of phytopathogenic fungi necessitates precision-targeted and sustainable antifungal strategies beyond conventional agrochemicals. This study presents a hierarchically structured micro/nanosystem (CMC@Eu-ZIF@ZnO) engineered for precision antifungal delivery by leveraging the specific virulence mechanisms of Botrytis cinerea . The composite features a dual core-shell architecture: a ZnO microsphere core encapsulated within a ZIF-8 intermediate shell and an outer carboxymethyl cellulose (CMC) coating. This intelligent design integrates pH- and cellulase-triggered release pathways, exploiting fungal-induced and enzymatic secretion for on-demand cargo delivery. Synergistic action between Eu and ZnO nanoparticles enhances membrane disruption and oxidative stress, resulting in superior antifungal activity. The system achieved 91.5 % cumulative release under dual stimuli and 67.9 % rainfast retention, with negligible phytotoxicity in soybean germination assays and effective lesion control in tomato leaves. By overcoming instability, non-target leakage, and limited responsiveness of conventional fungicides, this study establishes a microenvironment-responsive hierarchical delivery platform. This work highlights the potential of integrating natural antifungals with hierarchical nanostructures for eco-friendly, precision crop protection.

Aims Tea plants exhibit a strong preference for ammonium nitrogen (NH₄⁺-N), yet organic fertilizers release nitrogen slowly and are prone to nitrate leaching, createting a dual challenge of insufficient supply and loss. This study aimed to validate a synergistic strategy combining ammonifing bacteria and nitrification inhibitors to enhance organic nitrogen mineralization and NH₄⁺-N retention in tea plantion soils, and to elucidate the underlying microbial mechanisms. Methods A 56-day soil incubation experiment tested five treatments: control (CK), organic fertilizer (OF), OF with ammonifying bacteria (OM), OM + dicyandiamide (OMN1), and OM + 3,4-dimethylpyrazole phosphate (OMN2). Soil NH 4 + -N /NO 3 − -N dynamics, microbial communities, and functional genes were analyzed. Field trials further assessed the agronomic effects of four treatments (CK, OF, OMN1, OMN2) on tea yield and quality. Results The combined use of ammoniating bacteria and nitrification inhibitors synergistically enhanced NH 4 + -N availability by accelerating organic N mineralization and suppressing nitrification. This strategy reshaped microbial co-occurrence networks and enhanced the expression of nitrogen metabolism genes without altering overall diversity. enabling targeted N supply regulation. Field validation confirmed significant improvements in tea yield and quality. Conclusions Synergistic regulation of microbial nitrogen transformation offers a promising approach to optimize organic fertilization in tea plantations. By enhancing NH₄⁺-N supply and reducing nitrification loss, this strategy improves both soil nitrogen dynamics and tea production outcomes.

The extensive use of chemical pesticides has led to serious environmental concerns, highlighting the need for innovative pest control strategies that combine high efficiency with ecological sustainability. Plant essential oils (EOs), as natural and effective alternatives, hold great potential to replace conventional pesticides. However, their application is hindered by limitations such as burst release and short residual activity. In this study, EOs were encapsulated within a sodium alginate/polyethylene glycol diacrylate (SA/PEGDA) matrix to achieve sustained release. The resulting slow-release pellets (SRPs) exhibited optimal morphology and performance, effectively overcoming the issue of poor persistence commonly associated with EOs. The sustained-release period extended beyond 60 days. Application tests, demonstrated that SRPs efficiently eliminated pests, influenced their behavioral responses, and provided effective plant protection. Continuous low-dose exposure reduced adult longevity by 1.22 days, shortened oviposition period by 2.62 days, and decreased fecundity by 96.44 eggs, significantly affecting key life-history parameters. Gas chromatography-mass spectrometry (GC-MS) analysis identified several active compounds in the SRPs, suggesting that stable, sustained-release components play a crucial role in pest suppression. This study provides valuable insights into the development of eco-friendly and efficient EO-based formulations, contributing to the advancement of sustainable pest management and green pesticides.

Controlled-release fertilizers (CRFs) offer significant potential for reducing environmental pollution and enhancing fertilizer utilization efficiency. However, achieving improved controlled-release and degradability in high bio-content polyurethane (HB-PU) coated fertilizers remains challenging, limiting their further agricultural application. In this work, HB-PU coatings were synthesized via a one-pot process primarily using castor oil (CO), lysine diisocyanate (LDI), and polymethylene polyphenyl polyisocyanate (PAPI). Results demonstrate that the enhanced controlled-release performance of the HB-PU coating is associated with the type and concentration of metal ions within the complexation layer formed on the surface of the urea. After constructing the Cu coordination layer, the nutrient-controlled release period of castor oil-based polyurethane with bio-content over 70 % (PCU1-Cu) coated urea with 2.5 % coating percentage was extended by 20 days compared to the control. The chemical structure, thermodynamic stability, and microscopic morphology of the HB-PU with Cu coordination layer were analyzed. XPS confirms that the metal ion coordination was mainly enriched in the inner layer of the coating material. The Fenton-like reaction confirmed the presence of Cu ions in the PCU1-Cu coating and with catalytic reactivity. Degradation studies in NaOH solution demonstrated that introducing Cu ions accelerates the HB-PU degradation. The application of PCU1-Cu coated urea on Pakchoi ( Brassica rapa ssp. chinensis ) exhibited increased yield. This study prepared HB-PU controlled-release fertilizers with excellent controlled-release properties by constructing a metal coordination layer, while also providing a novel design method for supplementing essential trace metal elements for plant growth.

Background Plant viral infections threaten global food security and cause major crop losses. This study investigates the antiviral effects of biosynthesized Chitosan nanoparticles (ChNPs) with Bacillus subtilis 1211 EMCCN against potato virus Y (PVY) and their influence on tomato growth and yield. Results Scanning electron microscopy showed clusters of crystals on ChNPs, while transmission electron microscopy revealed that the nanoparticles were spherical, ranging from 12 to 198 nm. Energy-dispersive X-ray spectroscopy confirmed the presence of carbon, oxygen, sodium, and phosphorus, and Fourier-transform infrared analysis identified typical chitosan functional groups, including hydroxyl, carbonyl, and amine. Tomato leaves were treated with ChNPs, B. subtilis , or both to evaluate their effectiveness against PVY. The treated plants exhibited a marked reduction in both disease severity and PVY concentration compared to the untreated controls. By 28 days post-inoculation, infectivity decreased to 46.7% in plants treated with Bacillus subtilis, 33.3% with ChNPs, and reached the lowest level of 20% in the combined treatment. The combined priming strategy significantly enhanced plant growth attributes, with increases in shoot length (95.0%), root length (47.0%), leaf area (668.1%), plant height (30.7%), shoot and root fresh weight (370.0% and 162.9%), and shoot and root dry weight (562.7% and 127.7%). Biochemical and physiological analyses revealed substantial increases in total pigments (268.4%), flavonoids (112.2%), phenols (59.4%), α-tocopherol (92.1%), ascorbic acid (30.1%), anthocyanins (71.3%), peroxidase (51.9%), catalase (39.6%), polyphenol oxidase (73.6%), amino acids (119.9%), proline (93.3%), soluble sugars (128.0%), and proteins (614.0%) in shoots. Yield components, including carotenoids and anthocyanins, were also significantly enhanced. Importantly, oxidative stress indicators were markedly reduced, with malondialdehyde and hydrogen peroxide levels decreasing by 76.8% and 72.6%, respectively, in treated plants compared to infected plants. Conclusion These findings suggest that combination between ChNPs and B. subtilis offers an eco-friendly method to enhance tomato yield and effectively manage viral diseases by activating the plants' defense mechanisms.

The strong hydrophilicity of corn starch nanoparticles (CSNPs) limits their application as a Pickering emulsion gel stabilizer. In this study, CSNPs were modified with purple corn cob anthocyanins (PCCAs), a type of anthocyanin derived from processing waste. Fourier transform infrared spectroscopy and X-ray diffraction analyses confirmed that PCCAs were embedded in CSNPs via both hydrogen bonding and hydrophobic interactions. The three-phase contact angle increased from 51.77 ± 3.18° to 67.43 ± 1.08° after loading, suggesting the PCCA-modified CSNPs (PCCA-CSNPs) were more suitable than the CSNPs for stabilizing oil/water emulsion. The Pickering emulsion gel stabilized by PCCA-CSNPs (PCSPEGs) exhibited better storage stability than the Pickering emulsion gel stabilized by CSNPs (CSPEGs). A comparison of the rheological properties, creep-recovery properties, and interfacial properties between CSPEGs and PCSPEGs revealed that the combined effects of the more stable interfacial layer and the increased viscosity of the continuous phase of the emulsion gel contributed to the improved stability of PCSPEGs. Thus, PCCA-CSNPs represent a green, rapid, and economical hydrophobic modification method for CSNPs, and the stabilization mechanism of PCSPEGs was elucidated in this work.

Soil salinization severely degrades arable land and poses a significant threat to global food security. Different from the commonly adopted saline soil leaching method, this work proposes a sustainable and water-efficient soil remediation system. Mimicking the natural water cycle, this system, configured as a microclimate chamber, leaches salts from the soil and ultimately transfers them to the evaporator. 7-day operation demonstrates that the system can work steadily and achieve a water cycling rate of 7.12 kg m⁻² day⁻¹, removing 95.9 % of the salt from the soil. Scaled-up field tests indicate that, within 10 days, the majority of dissolved salts are transferred from the soil to the evaporator in two seasons, resulting in an efficient salinity reduction of the leachate (>90 %) and less water consumption, saving 87.13 % and 79.65 % water resources compared to the traditional method. The treated soil regained its capacity to support plant cultivation. By harnessing ambient solar energy and closed-loop water cycling, this work offers a sustainable, water-efficient strategy for saline soil remediation.
