Intelligent controlled-release nanopesticides have been a crucial tactic in advanced precision agriculture during the past few years, which can improve pesticide utilization and reduce environmental pollution. Herein, novel hydroxypropyl methylcellulose-based nanopesticide carrier (PCH) with pH-/enzyme-/near-infrared multiple responses was constructed by initial cross-linking dimethyl diallyl ammonium chloride subsequent copper ion chelation polydopamine coating. Avermectin (Av) further loaded to create intelligent release system (APCH) antisolvent precipitation. The of APCH increases under near-infrared light (NIR) conditions, an accumulative that is 3.26 times higher than without NIR. contact angles on cabbage leaves are 33 29% lower those water technical Av (Av-tech), respectively, verifying has good wettability property. Simultaneously, displays better insecticidal activity formulations because its outstanding ultraviolet (UV) stability Av. degradation rate less 2% 50 h UV light, considerably Av-tech (∼60%). biosafety assessments manifest PCH remarkable biological safety growth nontarget organisms certain range. Overall, bio-friendly multiple-response behaviors, excellent stability, foliar deposition performance, offer new strategy for sustainable agricultural development.

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.

Abstract Repeated epidemics caused by bacterial and fungal diseases pose a threat to global crop yields food security, therefore, updating the structure of existing microbicides improving pesticide bioavailability are challenging tasks, perhaps planning develop versatile supramolecular antimicrobial materials. Here, low‐cost multifunctional complex, named FT6@ β ‐CD, is constructed host‐guest encapsulation thienyl‐engineered ingredient (FT6) into ‐cyclodextrin. This integrated architecture can significantly reduce bounce splash behaviors droplets, improve wetting performance, eventually acquire excellent foliar deposition targeted delivery. Whereafter, ‐CD inhibit transcription type III secretion system (T3SS)‐associated genes, hypersensitive reaction, final pathogenicity from destructive pathogen Xanthomonas oryzae pv. ( Xoo ). Importantly, at lower dosage 200 µg mL −1 , presented in vivo control effects (protection 48.1%, curative 50.1%) against remarkably better than commercial bactericidal formulation thiodiazole‐copper. Additionally, other antifungal materials (FT24/FT25@HP‐ ‐CD/ ‐CD/Me‐ ‐CD) this study effectively treat Botryosphaeria dothidea Botrytis cinerea with higher efficiencies 86.8% 90.1% respectively. provides bright guidance for developing low‐cost, green, eco‐friendly controlling agricultural diseases.

Abstract The development of multi‐action pesticides presents significant advantages, including cost‐effectiveness, reduced application frequency, enhanced resistance management, and minimized environmental impact. Despite its efficacy in targeting chitin synthase both fungi insects, the insecticidal performance polyoxin B remains limited. To overcome this limitation, a novel nano‐formulation, B@ZTS is developed, utilizing agricultural byproducts, tea saponin, zein. This formulation features small particle size, high leaf deposition efficiency, excellent dispersion properties. Leveraging disulfide bond system, designed to respond intracellular reducing environment, enabling controlled release B. Remarkably, nano‐formulation facilitates penetration physiological barriers, achieving equivalent fungicidal at only one‐fifth dosage. work highlights potential eco‐friendly, cost‐effective, multifunctional nano‐pesticides, providing compelling solution for sustainable practices demonstrating broad applicability integrated pest disease management.

Abstract BACKGROUND Biotic and abiotic stresses threaten crop growth yield. Agrochemicals are an important way to mitigate biotic stress, while frequent low utilization potential environmental risk affect their sustainable use. In order improve pesticide utilization, it is common practice add tank‐mix adjuvants by reducing surface tension or forming spherical self‐assembly. However, there a lack of quantitative indicators screen suitable molecules for application. this work, critical factors based on physicochemical properties, kinetic thermodynamic parameters applied analyze regulatory mechanisms in dynamic processes, ultimately establish integrated strategy the management stresses. RESULTS Compared with traditional one‐dimensional linear amphiphilic molecules, two‐dimensional bio‐based especially sodium deoxycholate (NaDC), form self‐assembly could significantly promote deposition agrochemical droplets due maximum energy dissipation. Meanwhile, NaDC increased inhibition rate pyraclostrobin against Rhizoctonia solani from 24.4% about 100.0%, which was beneficial resistance stress. addition, harmful effects salt stress Oryza sativa increasing germination salt‐stressed seeds 30%, pesticides soil microbial communities eco‐friendly protection.
