Published: Jan. 24, 2025

Abstract Bacterial plant diseases, worsened by biofilm‐mediated resistance, are increasingly threatening global food security. Numerous attempts have been made to develop agrochemicals that inhibit biofilms, however, their ineffective foliar deposition and difficulty in removing mature biofilms remain major challenges. Herein, multifunctional three‐component supramolecular nano‐biscuits (NI6R@CB[7]@ β ‐CD) successfully engineered via ordered self‐assembly between two macrocycles [cucurbit[7]uril (CB[7]), ‐cyclodextrin ( ‐CD)] R )‐2‐naphthol‐based bis‐imidazolium bromide salt (NI6R). This macrocycles‐involved bactericidal material combines many advantages. 1) Alleviate the off‐target movement of droplets on hydrophobic blade surfaces. 2) Enhance biofilm‐disrupting ability. At a low‐dose 4.44 µg mL −1 , inhibition rate biofilm formation reached 78.3%. 35.5 potency remove 77.6%. 3) Efficiently hinder bacterial reproduction, swimming, extracellular polysaccharide production, enzyme secretion, virulence plants. These superior characteristics undoubtedly transmitted vivo control effect. 200 this smart exhibits efficiencies 49.6%/65.0%/85.4% against three kinds diseases (rice leaf blight, citrus canker, kiwifruit canker), respectively, surpassing commercial bactericide—thiodiazole‐copper‐20%SC (33.6%/41.5%/43.2%) NI6R (40.3%/51.2%/71.2%). Furthermore, NI6R@CB[7]@ ‐CD is biosafe non‐target organisms. study instructive for constructing sustainable crop protection.

Nanoporous 3D Polyurethane for Toosendanin Adsorption, Encapsulation, and High-Efficient Utilization

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

Published: Feb. 11, 2025

Nanoporous 3D-polyurethane (3D-PU) was prepared based on nano-CaCO3 templated controllably confined polymerization assembly and weak acid etching strategies. Nanopores with diameters ranging from 48 to 72 nm were distributed 3D-PU, facilitating its high BET surface area of 468.0 m2/g. The 3D-PU exhibited enhanced adsorption selectivity multi-H-bond donors acceptors, multirings contained compounds pore filling, hydrogen-bonding, π-π interactions; therefore, the novel had promising ability toosendanin (TSN) a maximum theoretical capacity 361.6 mg/g. Adsorption isotherm, kinetic, thermodynamic investigations revealed that heterogeneous supported by multiple sites, controlled chemical mechanism, endothermic, spontaneous, increased entropy. Based optimized adsorption, loading (LC) toward TSN attained 23.4%. After encapsulation, effective period extended 11 days, photolysis half-life 3.2 times, LC50 for Aphis citricola reduced approximately 6.0 indicating effectively improved performance TSN. porous can serve as carrier more pesticide safe, highly efficient, environmentally friendly utilization.

Published: Feb. 27, 2025

The development of hydrophobic pesticide formulations remains constrained by complicated manufacturing processes, excessive reliance on organic solvents, and indispensable surfactants. practical application dimethomorph (DIM) is hindered its nature, posing risks to nontarget organisms. Inspired the uptake nanomaterials plants, DIM was encapsulated in cyclodextrin (CD) cavity optimize water-solubility sustained-release rate. spatial confinement effect CD could facilitate thermostability DIM. DIM/CD inclusion complex solutions were electrospun fabricate nanofibers with bead-free smooth morphology. As predicted, release reached plateaus accumulative values approximately 75%. antifungal activity possesses much higher than for controlling Rhizoctonia solani Haematonectria hematococco, thereby enhancing bioactivity reducing spraying frequency. inhibition rates DIM/HPβCD DIM/HPγCD are found be 55.8% 53.6% within 144 h, respectively. This work explores feasibility as a delivery platform sustained agriculture production.

Efficiency and safety of nanopesticides, it takes two to tango. An overview of the lack of data on possible effects on human health

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 973, P. 179156 - 179156

Published: March 20, 2025

The use of pesticides has increased dramatically in recent decades, causing concern, particularly regarding human exposure and health effects. New strategies have been developed to limit the such hazardous substances. These include development "nanopesticides", which consist either nanomaterials used directly as active ingredient or carriers encapsulate ingredient. nanoformulated pesticide offer many advantages could be more efficient safer than their conventional counterparts. However, little is known about potential impact on health. aim this review provide an overview current studies investigating adverse effects nanopesticides, nanoencapsulated pesticides, A literature search was conducted PubMed Web Science databases using following keywords: (nano*) AND (pesticid* OR phytosanitar* herbicid* insecticid* fungicid* weedicid*) (toxi* inflam* oxidative stress) (human mammalian). Articles were excluded if: i) they reviews, ii) no toxicity data reported, iii) non-mammalian models, iv) not for delivery, v) articles written English. Of 2102 papers, only 27 included, highlighting lack nanopesticides mammalian models. In conclusion, although appear promising tools hazard extensive are still necessary ensure safety, especially health, before widespread application.

Multi‐Mechanism Encapsulation in a Bio‐Stimulant‐Based Smart Nanocarrier Enhances Fusarium Head Blight Control Through Synergistic Action and Triggered Release

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 30, 2025

Abstract Fusarium Head Blight (FHB) threatens global wheat production, exacerbated by fungicide resistance. Synergistic dual‐fungicide combinations show promise, but achieving precise, environmentally‐triggered release on the target remains challenging, and traditional pesticide delivery systems have biosafety issues. To address these limitations, a bio‐stimulant‐based smart nano‐delivery system for enhanced FHB management is introduced. Utilizing bio‐stimulant‐derived polyglutamic acid natural cyclodextrin derivatives, this co‐encapsulates tebuconazole (TEB) prothioconazole (PTC) through multi‐mechanism driven loading, enabling precisely‐ratioed (M PTC :M TEB = 4:3) pH‐responsive release. By strategically employing hydrogen bonding host‐guest interactions to control electrostatic forces with hydrophobic drive assembly of nanocarrier architecture, nanoscale construct achieves predictable, tailored kinetics, maximizing synergistic antifungal activity against graminearum. The eco‐friendly exhibits biocompatibility reduces phytotoxicity, characterization reveals membrane‐like nanoparticle deposition more efficiently delivers retains fungicide. Therefore, study underscores precision via loaded bio‐stimulant nanocarriers can overcome current limitations. And work highlights importance developing bio‐based stimuli‐responsive performance, paving way sustainable, effective, environmentally responsible control.
