Pine wood nematode (PWN) disease is a globally devastating forest caused by infestation with PWN, Bursaphelenchus xylophilus, which mainly occurs through the vector insect Japanese pine sawyer (JPS), Monochamus alternatus. PWN notoriously difficult to manage effectively and known as "cancer of trees." In this study, dual enzyme-responsive nanopesticides (AVM@EC@Pectin) were prepared using nanocoating avermectin (AVM) after modification natural polymers. The proposed treatment can respond cell wall-degrading enzymes secreted PWNs insects during tree intelligently release pesticides cut off transmission pathways realize integrated control disease. LC50 value AVM@EC@Pectin was 11.19 mg/L for 26.31 JPS. insecticidal activity higher than that commercial emulsifiable concentrate (AVM-EC), photostability, adhesion, target penetration improved. half-life (t1/2) 133.7 min, approximately twice AVM-EC (68.2 min). Sprayed injected applications showed had superior bidirectional transportation, five-times AVM contents detected in roots relative those when sprayed at top. safety experiment lower toxicity nontarget organisms application environment human cells. This study presents green, safe, effective strategy management

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.

Plant diseases caused by microbial pathogens pose a severe threat to global food security. Although genetic modifications can improve plant resistance; however, environmentally sustainable strategies are needed manage diseases. Nano-enabled immunomodulation involves using engineered nanomaterials (ENMs) modulate the innate immune system of plants and enhance their resilience against pathogens. This emerging approach provides unique opportunities through ability ENMs act as nanocarriers for delivering immunomodulatory agents, nanoprobes monitoring immunity, nanoparticles (NPs) that directly interact with cells trigger responses. Recent studies revealed application nanoscale agrochemicals strengthen immunity biotic stress enhancing systemic resistance pathways, modulating antioxidant defense systems, activating defense-related pathways reshaping plant-associated microbiomes. However, key challenges remain in unraveling complex mechanisms which influence molecular networks, assessing long-term environmental impacts, developing biodegradable formulations, optimizing targeted delivery methods. review comprehensive investigation latest research on nano-enabled strategies, potential action, highlights future perspectives overcome existing disease management.

Pine wilt disease is caused by Bursaphelenchus xylophilus invasion and has a great impact on global pine resources. Injection of emamectin benzoate (EB) into trunks an effective way to control B. xylophilus. However, EB limited aqueous solubility, easily photodissociates, its long-term use causes resistance problems. In this study, the metal-organic framework material ZIF-8 was prepared, loaded onto through physical adsorption, resulting in pH-responsive EB@ZIF-8 nanopesticide with high drug loading rate (36.04%). Simulated release experiments under different pH conditions showed cumulative 64.43% within 10 h at 5.0, which increased as decreased, compared 7.0 9.0. positive insecticidal activity laboratory biological test (LC50 = 52.503 mg/L). addition, 7 days after trunk injection Pinus massoniana, residuals were detected all parts branches, lowest residue level being 73.39 mg/kg. The proportion lower, middle, upper branches P. massoniana gradually increased, reaching 43.92% 28 injection, indicating that distributed evenly tree. Therefore, had good morphology, structure, performance. also exhibited nematocidal ability due smaller particle size rapid transport massoniana. This study provides new approach for development highly preparations, improvement pesticide utilization, control.

As the second most important fungal pathogen, Botrytis cinerea (B. cinerea) poses a serious threat to crop yields and agricultural safety. Pyraclostrobin (PYR), broad-spectrum QoI fungicide, has been widely utilized since its launch in 2003. However, inhibitory effects of both PYR technical formulations on B. are not outstanding. Even at concentration 50 μg/mL, inhibition rates by remain below 85%. In this work, we prepared an acid-responsive Pickering emulsion encapsulating (PYR@BTIB-PE), which completely inhibited low concentrations (25 μg/mL) for first time. The PYR@BTIB-PE achieved fragmentation release within 4 min pH 5, was consistent with around cinerea. can rapidly when infected increased cinerea, thereby enhancing efficacy PYR. addition, released organic solvent from enhanced passing property membrane, facilitating more enter body improvement membrane rapid response worked together achieve complete Furthermore, flexible amphiphilic structures interaction leaf surface, suppressed droplet splashing, promoted spreading, reducing pesticide loss improving utilization rate pesticide. This study presents efficient strategy inhibiting is also expected be extended other antifungal preparations.
