Seventy percent of global freshwater resources are consumed by agriculture, leading to severe water shortages due to the increasing demand for water in irrigated agriculture, which in turn poses a significant threat to food security. To address this challenge, innovative solutions are needed to optimize water use in agriculture. In this study, sodium lignosulfonate/chitosan/calcium chloride amphiphilic collection hydrogel (CSL-CaCl 2 ) is prepared. This hydrogel captures water from the atmosphere for soil water harvesting, thereby reducing the requirement for irrigation water. The hydrogel captures moisture from the air through its salt and porous structures, transferring it to a polymer network for storage. When exposed to daylight, the water-absorbed hydrogel is able to quickly release water into the soil, increasing the soil water content. The amount of water released from the hydrogel is 0.81 kg∙m −2 , equivalent to increasing the average annual precipitation in the temperate monsoon climate zone ( i.e. , Tianjin, China) by 51 %, which could effectively reduce the demand for agricultural irrigation water. The hydrogel not only promotes plant growth, but also has excellent water retention, improved soil physicochemical properties and exhibits excellent degradability. This work provides important insights for alleviating water shortages in irrigated agriculture.

Slugs pose a significant threat to agriculture, causing substantial crop damage and economic losses. Traditional molluscicides harm nontarget organisms and endanger ecosystems. Environmentally friendly molluscicides that ensure safety for humans and animals and promote sustainable agriculture are urgently needed. This study is the first to explore the fumigant toxicity, contact toxicity, and repellent effects of four monoterpenoids (geraniol, citral, geranyl nitrile, and citronellal) against Philomycus bilineatus. Compared to metaldehyde, monoterpenoids exhibited stronger contact toxicity, leading to rapid slug elimination (within 4 h), while metaldehyde caused death in slugs over a longer period of 48 h. Among the monoterpenoids, citral has weaker contact toxicity compared with the other three compounds, and geranyl nitrile (GN) and citronellal have stronger fumigant toxicity than the other two compounds. In terms of repellence and antifeeding effects, citral has the weakest toxicity. GN and citronellal stand out with excellent molluscidal activity (LC50 values of 0.10 and 0.14 g/L, respectively). The computational results based on the density functional theory (DFT) indicate that appropriate energy gaps, electrophilicity indices, and molecular softness correlate with the high molluscidal activity of monoterpenoids. From the computational results of this study, GN and citronellal, which have a moderate energy gap (approximately 0.200 eV), show the best effectiveness in controlling the slugs. In addition, unlike metaldehydes, which have a long half-life and limited biodegradability, these monoterpenoids have low toxicity and are easily degradable in the environment, making them more environmentally friendly. These findings underscore the potential of monoterpenoid compounds as eco-friendly alternatives for managing slugs in agriculture and gardens, thereby reducing reliance on traditional chemical pesticides.

In order to solve the problem of difficult precise nutrient release caused by loose pores in bio-based coated controlled-release fertilizers, this study explores the integration of Metal–Organic Framework (MOF) materials into bio-based coatings. Specifically, MOF-303 is synthesized and used to modify biocomposite coatings mainly derived from natural bio-polyol castor oil, which improved the controlled release performance through unique self-assembling and pore-forming properties of MOF-303. Characterization confirmed the successful incorporation of MOF-303 into the bio-based coatings, resulting in a smoother surface and fewer pores. Specifically, MOF-303 is synthesized and used to modify biocomposite coatings mainly derived from castor oil, which enhanced the controlled-release performance by adjusting the pore structure of the coating. The modified CRFs demonstrated improved controlled-release performance, with nitrogen (N) release periods extending from 63 days in unmodified coatings to 77 and 105 days with 1% and 1.5% MOF-303, respectively. Application trials on potted spinach revealed significant benefits, with yield increases of 37.51% and 30.83% under U and M1 treatment, respectively. This study highlights the potential of MOF-303-modified bio-based CRFs (MBCFs) to offer sustained and precise nutrient supply, thereby improving agricultural productivity and efficiency.

Cadmium (Cd) contaminant in soil can pollute crops and poison consumers higher in the food chain. Sorghum ( Sorghum bicolor (L.) Moench) is a promising bioenergy crop that can absorb and accumulate Cd from soil while generate renewable biomass resources for bioethanol or other valuable products, and limit waste production by rational utilization of all components. In this study, a sustainable agricultural strategy was presented and six sorghum cultivars grown under field conditions for the phytoremediation of Cd-contaminated agricultural soil were investigated with the goal of comparing their ability to accumulate Cd and their theoretical bioethanol yields (Cd concentration in the soil was 0.25 and 0.96 ppm). Striking differences were found in the Cd accumulation of these sorghum cultivars, and the result indicated that the Cd accumulation in stalks increased with maturity. The total absorbability of Cd ranged from 19.6 to 148 g/ha, and N6G60 sorghum showed the highest Cd accumulation with a concentration of 9.16 ppm in the stalk on a dry basis. The theoretical yield of bioethanol ranged from 5510 to 7510 L/ha. The overall performance of N6G60 and 15016 sorghums surpassed that of other sorghum cultivars because of their stronger capacities for Cd translocation and higher theoretical yields of bioethanol. Considering the experimental results, as well as the potential ethanol yield and growing situations of sorghums, 15016 sorghum was considered the cultivar showing the most promise for future applications.

Multifunctional material for simultaneous pollutants removal and nutrient release is a novel, economical, and sustainable strategy to reuse agricultural wastewater and improve crop growth. Herein, we synthesized a multifunctional porous carbon by using β-cyclodextrin MOF (β-CD MOF) both as precursor and potassium source. The obtained carbon material (β-CD MOF-NPC) was equipped with microporous structure, large surface areas, and rich potassium element content, as determined by comprehensive characterization results. The batch adsorption experiments indicated β-CD MOF-NPC possessed efficient adsorptive removal ability of four amide herbicides from water, which might be through π–π interaction, hydrogen bonding, and electrostatic interaction. Besides, the β-CD MOF-NPC could effectively contribute to the growth of rice seedlings cultured in herbicide-contaminated wastewater by simultaneous adsorption of herbicides and release of potassium ions in the pot experiments. This study indicated β-CD MOF-NPC integrated the function of adsorbent and fertilizer, which is a promising material for sustainable and economical agriculture.

Intelligent delivery formulations of agrochemicals have had a great impact on improving utilization efficiency, reducing chemical usage and easing the risk on the environment. However, constructing smart carriers for multi-agrochemicals to simultaneously control multiple botanic diseases, remains a challenge. In this study, a core-satellite MOF-on-MOF hybrid was designed for intelligent pest and fungus management. Zirconium-based metal–organic framework (UIO) nanoparticles were synthesized as metal–organic framework (MOF) cores to load the insecticide dinotefuran (DNF). Subsequently, a fungicide tebuconazole (Teb) loaded zeolitic imidazolate framework (ZIF) was formed in situ as MOF satellites. The loading contents of DNF and Teb were 6.87% and 8.59%, respectively. DNF released rapidly under alkaline conditions corresponding to the microenvironment of pests, whereas Teb released preferentially under acidic environment. The EC 95 of the MOF-on-MOF hybrid against Exserohilum turcicum was 3.5 times lower than that of Teb alone. After 48 h, the mortality of armyworm treated with 3.0 mg/L MOF-on-MOF hybrid was 87%. The UV resistances of DNF and Teb were 7.0 and 1.9 times higher, respectively, than that of the free pesticides. This work provides a facile technology for precise delivery of multi-agrochemicals, holding substantial promise for sustainable agriculture.

Nanotechnology contributes to the development of biopesticides with reduced toxicity, increased stability, improved biosafety, and higher activity against targets. It has demonstrated great potential as a solution for practical applications of essential oils. Herein, the HLB method developed two Artemisia argyi essential oil-loaded nanoemulsions (AEOnano). Further systematically optimizing the ratio led to small droplet size (<200 nm) and low PDI (<0.3). As anticipated, the AEOnano demonstrated robust physical stability when subjected to various stressors. Notably, both indoor and outdoor pot experiments demonstrated that AEOnano outperformed ordinary A. argyi essential oil aqueous emulsions (AEOAE) in weed control. These nanoemulsions allowed a 2–4 times reduction in AEO dosage while maintaining the same weed-killing efficacy. The superior improvement attributed to the nanoemulsions enhanced leaf-wetting capability, improved leaf retention, and resistance to wash-off. In addition, biosafety assessment indicated that AEOnano did not affect the plants ( Artemisia argyi , Chrysanthemum morifolium , cotton), which provide orientation for its practical application. Therefore, this study introduces a promising approach to enhance the effectiveness of AEO-based herbicides, which will have a broad application prospect in sustainable agriculture.

The presence of thiocyanate (SCN−) in irrigation water has adverse effects on both plant growth and crop output. Hydrogen sulfide (H2S) is an important gaseous signaling molecule that can alleviate SCN−stress. Flavonoids are secondary compounds produced by plants and are ubiquitous in the plant kingdom. They play important roles in several physiological and biochemical processes. To investigate the effect of exogenous H2S on the growth of early rice plants under SCN−stress, we carried out a hydroponic experiment focusing on the interaction of exogenous H2S with flavonoids. In this study, a hydroponic experiment was performed to investigate the behavior of SCN−when subjected to varying effective doses (EC20: 24.0 mg/L; EC50: 96.0 mg/L; and EC75: 300.0 mg/L). The findings indicated that the relative growth rate (RGR) of the plants treated with H2S + SCN−was greater than that of the plants treated with SCN−alone. Higher amounts of flavonoids were detected in the shoots than in the roots, with more variability in the shoots. The early warning level results showed that most of the flavonoids were present at levels I and II, while quercetin was present at level IV. Genetic expression variation factor (GEVF) analyses revealed an increase in the quantity of “promoter genes” with increasing SCN−concentration in both rice tissues. Furthermore, administering external H2S while exposing rice tissues to SCN−resulted in a considerable decrease in the levels of reactive oxygen species. This study provides novel insights into the regulation of flavonoid levels in rice plants by exogenous H2S, facilitating enhanced resistance to SCN−stress and promoting sustainable agriculture.

Alkali-hydrolyzed lignocellulose was liquefied into polyols by acid-catalyzed dissolution, and then cross-linked with castor oil to prepare bio-based cross-linked polyurethane . Then, bis (2-hydroxyethyl) disulfide (SS) with self-healing function was used to reduce foaming in the curing process of polyurethane coating. Afterwards, disulfide bond modified cross-linked bio-based polyurethane coating (BCSPU) was applied to controlled-release urea (CRU). The results of excitation-emission matrices indicated that SS made the coating smoother and denser and preventing the release of non-film-forming substances. Cross-linking modification technology significantly extended the controlled release longevity of CRU by 77.3%, and the self-healing modification further prolonged the nitrogen release longevity by 61.5%. In addition, modified coating materials were non-toxic to wheat seeds and easily biodegradable in the soil. Cross-linking, self-healing modified controlled-release urea has enormous application potential in sustainable agriculture .

BACKGROUND Widespread resistance of insect pests to insecticides and transgenic crops in the field is a significant challenge for sustainable agriculture, and calls for the development of novel alternative strategies to control insect pests. One potential resource for the discovery of novel insecticidal molecules is natural toxins, particularly those derived from the venoms of insect predators. RESULTS In this study, we identified three insecticidal proteinaceous toxins from the venom glands (VGs) of the predatory stink bug, Arma custos (Hemiptera: Asopinae). Transcriptomic analysis of A. custos VGs revealed 151 potentially secreted VG-rich venom proteins. Three VG-rich venom proteins (designated AcVP1 ~ 3) were produced by overexpression in Escherichia coli . Injection of the recombinant proteins into tobacco cutworm ( Spodoptera litura ) larvae showed that all of the three recombinant proteins caused paralysis, liquefaction and death. Injection of recombinant proteins into rice brown planthopper ( Nilaparvata lugens ) nymphs showed higher insecticidal activities, among which a trypsin (AcVP2) caused 100% mortality postinjection at 1.27 pmol mg −1 body weight. CONCLUSION A natural toolkit for the discovery of insecticidal toxins from predatory insects has been revealed by the present study. © 2024 Society of Chemical Industry.

Although various eco-friendly and sustainable biobased polyurethane-coated controlled-release fertilizers (BPCFs) have been developed, their applications were limited by the bio-based coating contained many microscopic holes. In this work, a nano-soy-protein microcapsule-enabled self-healing biopolyurethane-coated controlled-release fertilizer (NSBCF) with enhanced controlled-release performance was fabricated. Nanoscale soy-protein microcapsules (SMCs) were prepared from soy-protein isolate (SPI) and poly (lactic-co-glycolic acid) using the water-oil-water emulsification technology. The self-healing biopolymer coatings of NSBCF with uniformly dispersed SMCs were constructed through self-assembly. The controlled-release longevity of NSBCF was >28 days longer than that of the BPCF with the unmodified coating. The self-healing mechanism of NSBCF was determined by directly observing the restoration area and the 3D pore distribution of coating using fluorescence labeling and X-ray computed tomography . After being released from the SMCs, SPI self-repaired the coating by reacting with glutaraldehyde to form solid resins to clog the microscopic holes. The SMCs-enabled self-healing process successfully reduced the nutrient release rate and extended the nutrient release longevity of NSBCF. This novel biobased controlled-released fertilizer with self-healing function represents a new direction for the development of high efficiency and environmentally friendly fertilizers to improve agriculture and food sustainability .

Stimulus-responsive pesticide or fertilizer systems have been emerged to improve the use efficiency of agrochemicals , reduce over-application and ensuing environmental problems. However, environmental-friendly synthesis of these systems still remain challenging. In this work, an environmental-friendly synthesis strategy has been developed to form a pesticide and fertilizer combination to achieve the integration of plant protection and nutrient supply. This pesticide-fertilizer combination system was fabricated using ammonium zinc phosphate (ZNP) and in-situ synthesized zeolitic imidazolate framework-8 (ZIF-8) as nutrients resources, and dinotefuran (DNF) as a pesticide. DNF was encapsulated in-situ (loading capacity of 12.32 ± 0.46%) during the ZIF-8 crystal synthesis process, rather than loaded by further adsorption, which improved its stability and prevented premature or rapid release. The hydrophobic ZIF-8 provided a pH-responsive slow-release behavior. The cumulative released DNF within seven days at pH 4.0, 7.0 and 10.0 was 66.30%, 40.41%, and 37.44%, respectively. The pesticide-fertilizer combination system showed significant effects on corn seed pre-cultivation, soil cultivation and pest control. This work provides a strategy for the integration of pesticide and fertilizer, which will reduce negative environmental effects caused by their over-applications and have great potential in modern sustainable agriculture.
