Abstract BACKGROUND Suitable nano‐pesticide carriers play a crucial role in enhancing the utilization efficiency of pesticides. Among these, mesoporous silica nanoparticles (MSNs) are most promising candidates for large‐scale and safe pesticide applications. RESULTS In present work, functionalized MSNs were demonstrated to be effective mitochondrial‐targeted delivering strobilurin fungicides (mitochondrial respiratory chain inhibitors). bi‐functionalized with carboxymethyl chitosan (CMC), which is pH‐responsive, (4‐carboxybutyl) triphenylphosphonium bromide (TPP), mitochondrial targeting. The loading capacity model pyraclostrobin (Py) on carrier reached 32%. vitro release experiments Py sustained performance carriers. Co‐localization mitochondria confirmed that targeting by nanoparticle carrier. Bioactivity assays showed superior antifungal activity Py@MSNs‐CMC‐TPP compared mono‐functionalized commercial suspension products. Moreover, even when concentrations Py@MSNs‐CMC increased 200% relative Py@MSNs‐CMC‐TPP, inhibition remained lower. This indicates reduced required amount while its efficiency. CONCLUSION With application pesticides, such as methoxyacrylates succinate dehydrogenase inhibitors, have significant potential emerge promising, environmentally friendly fungicide formulation. © 2025 Society Chemical Industry.

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.

Preparation and Properties of Fomesafen@SiO₂-Starch Microspheres for Herbicide-Controlled Release

ACS Agricultural Science & Technology, Journal Year: 2024, Volume and Issue: 4(5), P. 603 - 613

Published: May 7, 2024

Fomesafen serves as a widely employed selective herbicide for addressing broadleaf weeds, but the short duration of efficacy limits utilization efficiency. There exists an exigent requirement to extend its through controlled release mechanisms. Fomesafen@SiO2-starch microspheres with α-amylase responsiveness were synthesized direct binding drug-loaded silica and modified starch. This fabrication method capitalizes on enzymatic degradation potential outer starch layer by amylase. In contrast earlier analogous structures that exhibited inferior drug loading efficacy, prepared fomesafen@SiO2-starch demonstrated significantly enhanced capacity up 35.7%. Furthermore, in comparison fomesafen technical, notable mitigate photolysis layer. Additionally, favorable wettability adhesive properties. At recommended dosage, herbicidal against Brassica napus L. Portulaca oleracea over 14 days was observed be comparable concurrently exhibiting degree sustained release. These findings underscore regulating fomesafen, thereby presenting promising avenue development sustainable delivery systems agriculture.
