ACS Nano, Journal Year: 2024, Volume and Issue: 18(8), P. 6533 - 6549

Published: Feb. 14, 2024

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.

Effects of Exposure to Different Types of Metal–Organic Framework Nanoparticles on the Gut Microbiota and Liver Metabolism of Adult Zebrafish

ACS Nano, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 31, 2024

Metal–organic framework nanoparticles (MOF NPs) have received much attention for their potential use in nanopesticides. However, little is known about the health and environmental risks associated with these materials. In this study, toxicological responses of zebrafish exposed to five MOF NPs short long periods time were evaluated. The acute toxicity results showed that embryos adult was order Cu-MOF > ZIF-90 ZIF-8 Fe-MOF Zr-MOF. Histopathological analysis revealed ZIF-8, ZIF-90, caused liver swelling vacuolization zebrafish. cellular ultrastructure severely damaged mitochondrial structure intestinal epithelial cells cells. 16S rDNA sequencing data all significantly altered dominant microorganisms intestine. microbial markers inflammation, Proteobacteria (Aeromonas, Plesiomonas, Legionella), increased Fe-MOF, Zr-MOF, treatment groups. Metabolomics indicated levels inflammatory promoting factors (Leukotriene E4, 20-hydroxyeicosatetraenoic acid) arachidonic acid metabolism decreased, suppressing (8,9-epoxyeicosatrienoic increased. Metabolites related oxidative stress, such as glutamine, pyridoxamine, l-glutamic vitamin B6 other signaling pathways, reduced. Overall, suggest different had widely varying zebrafish, further should be paid real environment.

New Isoxazoline Cyclopropyl-Picolinamide Derivatives as Potential Insecticides

Journal of Agricultural and Food Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 7, 2025

Isoxazoline insecticides exhibit broad-spectrum insecticidal activity against insect pests. However, the high toxicity to honeybees limits their application in pest management. To explore reducing of isoxazoline derivatives bees, a series new cyclopropyl-picolinamide were designed and synthesized. Bioassays revealed that FSA37 showed excellent Plutella xylostella, Spodoptera litura, exigua, with LC50 values 0.077, 0.104, 0.198 mg/L, respectively. These results surpass those fluxametamide, which displayed 0.605, 0.853, 1.254 mg/L. Furthermore, exhibited notable Solenopsis invicta. Importantly, bee studies indicated possesses significantly lower acute oral compared fluralaner fluxametamide. Quantum chemical calculations molecular docking suggest fragment may be crucial for both biological safety nontarget organisms. In conclusion, represents promising candidate highly effective environmentally friendly insecticide.
