Biopesticides have emerged as a global trend to minimize the risks associated with synthetic agrochemicals. However, their stability and efficacies remain challenges for widespread application. Herein, co-assembled nanoparticles (AT NPs or AP NPs) based on azadirachtin (AZA) tannic acid (TA) phenylalanine (PA) are constructed in aqueous solution through self-assembly technology. The small particle size, low PDI, high ζ-potential, related other physicochemical characteristics of can improve wettability, adhesiveness, rain erosion resistance, photostability compared commercial AZA formulation. Importantly, co-assemblies bidirectional pH-responsive disassembly acidic alkaline solutions, allow them respond microenvironmental stimuli targets enable controlled release AZA. nanosystems demonstrated remarkable vitro vivo insecticidal activities against Ostrinia furnacalis Aphis gossypii. This study illustrates distinctive perspective developing eco-friendly nanosystems, highlighting water-based treatment method biopesticides improved properties utilization efficiency. delivery limits Here, is plant secondary metabolites efficient drug delivery, demonstrating pest management, activation defensive capacity, while increasing production yield crops.

Abstract The inefficient delivery of herbicides causes unpleasant side effects on the ecological environment. Protoporphyrinogen oxidase (PPO)‐inhibiting rely presence external light to exert activities and thus their performance in field is extremely susceptible Here, taking acifluorfen (ACI) as a model PPO‐inhibiting herbicide enhance efficacy by boosting utilization rate sunlight, amphiphilic cationic CDs (CPC‐CDs) from cetylpyridinium chloride (CPC) precursor, first prepared supplementary source generator, subsequently co‐assembled with ACI through non‐covalent bond interactions obtain stable fluorescent nanoparticles (ACI@CPC‐CDs). ACI@CPC‐CDs fascinating physicochemical properties can penetrate leaves weeds stomata undergo long‐distance transport cell intervals. Under low intensity, CPC‐CDs be applied internal promote formation more singlet oxygen damage leaf membrane, consequently improving herbicidal activity ACI. Moreover, safety evaluation demonstrates no risk non‐target organisms Therefore, this work offers promising strategy for efficient light‐dependent opens new insights into application development sustainable agriculture.

Based on the modified cross-linking of degradable natural polymers chitosan oligosaccharides (COS) and gelatin (GEL) via introduction a functional bridge 3,3'-dithiodipropionic acid, this study constructed an environmentally responsive dinotefuran (DNF) delivery system (DNF@COS-SS-GEL). The disulfide bond (-S-S-) endowed DNF@COS-SS-GEL with redox-responsive properties, allowing for rapid release pesticides when stimulated by glutathione (GSH) in simulated insect. Compared commercial DNF suspension concentrate (DNF-SC), showed superior wet spreading retention performance cabbage leaves reduced contact angle (57°) at 180 s 4-fold increased capacity after rainfall washout. Nanoencapsulation effectively improved UV-photostability only 31.4% decomposition rate 96 h. small scale large specific surface area resulted excellent uptake transportation properties plants as well higher bioactivity against

Journal of Agricultural and Food Chemistry, Год журнала: 2024, Номер 72(42), С. 22985 - 23007

Опубликована: Окт. 9, 2024

Efficient management of crop diseases and yield enhancement are essential for addressing the increasing food demands due to global population growth. Metal-organic frameworks (MOFs), which have rapidly evolved throughout 21st century, notable their vast surface area, porosity, adaptability, establishing them as highly effective vehicles controlled drug delivery. This review methodically categorizes common MOFs employed in disease details effectiveness against various pathogens. Additionally, by critically evaluating existing research, it outlines strategic approaches design drug-delivery explains mechanisms through enhance resistance. Finally, this paper identifies current challenges MOF research suggests directions future research. Through in-depth review, seeks enrich understanding applications offers valuable insights researchers practitioners.
