An ideal green leaf-deposited pesticide formulation should offer advantages such as good water dispersibility, strong foliar affinity, sustained or controlled release of active ingredients, photostability and rain-fastness, minimal nontarget toxicity, use nontoxic organic solvents, degradable adjuvants. In line with this objective, we present preparation a colloidal using optimized lysine-derived carbon dots (LysCDs)-modified CaCO3 (LysCDs/CaCO3) particles the carrier abamectin (Abm) ingredient. The loading capacity in (LysCDs/CaCO3/Abm) is 1.7 to 2.1 times higher than that its counterpart (CaCO3/Abm) prepared without LysCDs, which attributed increased specific surface area pore volume LysCDs/CaCO3 particles. Due acid-induced degradation CaCO3, for LysCDs/CaCO3/Abm accelerated under weakly acidic conditions, accompanied by Ca2+ ions fluorescence changes LysCDs. incorporation LysCDs enhances adhesiveness pesticide, resulting highest degree retention when exposed ultraviolet (UV) light rainfall, compared free-form CaCO3/Abm. This results best performance pest control on Plutella xylostella both indoor outdoor tests. Nontarget biocompatibility evaluations show exhibits lower acute toxicity zebrafish earthworms abamectin. addition, favored residue adjuvant material after release, converted into harmless ions, CO2, Therefore, work designs safer more effective deliver residue, realizing trajectory basically "circular green".

Conventional agrochemicals are underutilized due to their large particle sizes, poor foliar retention rates, and difficult translocation in plants, the development of functional nanodelivery carriers with high adhesion plant body surface efficient uptake plants remains challenging. In this study, a system based on pectin-encapsulated iron-based MOF (TF@Fe-MOF-PT NPs) was constructed enhance utilization thifluzamide (TF) rice by taking advantage pectin affinity for cell walls. The prepared TF@Fe-MOF-PT NPs exhibited an average size 126.55 nm, loading capacity 27.41%, excellent dual-stimulus responses reactive oxygen species pectinase. Foliar washing experiments showed that were efficiently adhered surfaces leaves stems. Confocal laser scanning microscopy fluorescently labeled bidirectionally delivered through vascular bundles plants. vitro bactericidal activity better inhibitory than TF suspension (TF SC), EC50 0.021 mg/L. A greenhouse test more effective SC at 7 14 d, control effects 85.88 78.59%, respectively. It also reduced inhibition seed stem length root promoted seedling growth. These results demonstrated can be used as pesticide delivery intelligent release applied sustainable pests diseases.

The flourishing progress in nanotechnology offers boundless opportunities for agriculture, particularly the realm of nanopesticides research and development. However, concerns have been raised regarding human environmental safety issues stemming from unrestrained use non-therapeutic nanomaterials nanopesticides. It is also important to consider whether current development strategy based on nanocarriers can strike a balance between investment return, if complex material composition genuinely improves efficiency, safety, circularity Herein, we introduced concept with minimizing carriers (NMC) prepared through prodrug design molecular self-assembly emerging as practical tools address limitations, compared it employing (NNC). We further summarized NMC examined potential challenges its preparation, performance, production. Overall, asserted that systems serve innovative driving force catalyzing green efficient revolution nanopesticides, offering way out predicament.

Efficient delivery of nanoparticles (NPs) to plants is important for agricultural application. However, date, we still lack knowledge about how NPs' charge matters its translocation pathway, i.e., symplastic and apoplastic pathways, in plants. In this study, synthesized used negatively charged citrate sourced carbon dots (C-CDs, −37.97 ± 1.89 mV), Cy5 coated C-CDs (Cy5-C-CDs, −41.90 2.55 positively PEI (P-CDs, +43.03 1.71 P-CDs (Cy5-P-CDs, +48.80 1.21 mV) investigate the role surface charges coatings on employed pathways (symplastic pathways) NPs Our results showed that, different from higher fluorescence intensity Cy5-P-CDs extracellular than intracellular space, Cy5-C-CDs was similar between space cucumber cotton roots. It suggests that CDs were translocated via both but mainly pathway. Furthermore, our root applied demonstrated leaf did (8.09 0.99 vs 3.75 0.23) (7.27 1.06 3.23 0.22), indicating have a efficiency do CDs. should be noted not affect cell activities, ROS level, photosynthetic performance cotton, showing good biocompatibility. Overall, study only figured out transportation roots compared with employment pathway CDs, also found could more efficiently imparting negative NPs, at least efficient 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.
