Facile pesticide nanocapsules were successfully prepared by directly encapsulating the antisolvent precipitation of pesticides through instantaneous “on site” coordination assembly of tannic acid and Fe3+, avoiding tedious preparation, time consumption, and large amounts of organic solvents. The pesticide nanocapsules showed excellent resistance to ultraviolet photolysis and rainwater washing owing to the nanocapsule walls. The smart pesticide nanocapsules exhibited the controlled release of pesticides under multidimensional stimuli, such as acidic/alkaline pH, glutathione, H2O2, phytic acid, laccase, tannase, and sunlight, which were related to the physiological and natural environments of crops, pests, and pathogens. The tebuconazole nanocapsules not only enhanced the fungicidal activity against Fusarium graminearum and effective control efficacy in wheat powdery mildew through foliar spray and seed coating, but also improved the biosafety of target plant growth and nontarget organisms. The facile, smart, efficient, safe, and green pesticide nanocapsules using the universal strategy have broad application prospects in ecoagriculture.

The widespread use of petroleum-based plastic mulch films in agriculture has led to severe environmental pollution, which has driven increasing interest in the development of biodegradable plastics derived from biomass resources. Herein, eco-friendly composites/films were fabricated using soy protein isolate (SPI) and sodium lignosulfonate (LS) as the primary biomass components through a simple casting method. The SPI/LS composites exhibited impressive mechanical properties, including high tensile strength (15.4 MPa), fracture strain (290 %), toughness (33 MJ‧m −3 ), Young's modulus (100 MPa), and excellent fatigue resistance (maintaining 5 MPa strength after 10 cycles of repeated stretching at 150 % strain). These properties were closely linked to multiple molecular interactions within the composites. Fourier transform infrared spectroscopy and X-ray diffraction analysis revealed that the protein's secondary structure transitioned to a more ordered state, with enhanced hydrogen bonding between SPI and LS. Furthermore, the SPI/LS films demonstrated excellent UV-shielding, moisture retention capabilities, and enhanced crop seed germination rates. Plant seedling tests indicated that after biodegradation in soil, the films released nitrogen-containing ions such as NH 4 + vital for healthy root growth. Therefore, the eco-friendly and biodegradable SPI/LS composites/films hold great potential as mulching films for agricultural crop cultivation, improving crop yields while reducing the need for fertilizers.

The development of novel, safe, and efficient pest and disease control technologies for agricultural crops remains a pivotal area of research. In this study, by combining ZIF-8 and ZIF-90, a water-stable, pH-responsive bilayer MOF nanoparticle (NP) named Z8@Z90 was created, and tebuconazole (TEB) was added to form T@Z8@Z90, used for controlling peanut southern blight. The loading efficiency of TEB within the T@Z8@Z90 reached 26.15%, enabling rapid release in acidic environments triggered by oxalic acid (OA) secreted by Sclerotium rolfsii. In vitro experiments showed that T@Z8@Z90 can regulate the oxalic acid secretion of S. rolfsii and destroy its cell membrane structure. Additional experiments revealed that T@Z8@Z90 reduced sclerotial formation, decreased the total protein content of sclerotia, and influenced their sensitivity to pesticides, thereby mitigating the risk of reinfection by S. rolfsii. Notably, T@Z8@Z90 exhibited efficient translocation within peanut seedlings, being absorbed through the roots and transported to the leaves. At a concentration of 200 mg/L, T@Z8@Z90 exhibited high safety profiles for peanut seedling growth compared to the TEB suspension. Moreover, T@Z8@Z90 is safer for earthworms than TEB SC. Overall, this study offers valuable insights for the management of soil-borne diseases in agriculture and contributes to the advancement of sustainable agricultural practices.
