To assess the ecological risk of microplastics (MPs) in agricultural systems, it is critical to simultaneously focus on MP-mediated single-organism response and different trophic-level organism interaction. Herein, we placed earthworms soils contaminated with concentrations (0.02% 0.2% w/w) polyethylene (PE) polypropylene (PP) MPs investigate effect tomato against

ABSTRACT Maize is a critical component of global food security; however, pests like the oriental armyworm ( Mythimna separata Walker) cause significant yield losses to this crop. Conventional control approaches for managing insect rely on pesticide applications, which pose environmental risks and can lead pest resistance. Thus, necessity alternative management strategies emphasised. Silicon (Si) proposed as substitute due its ability mitigate plethora biotic abiotic stresses in plants. To evaluate effectiveness Si controlling armyworm, maize plants were treated with three concentrations (T1: 500 mg/L, T2: 750 T3: 1000 mg/L) then infested larvae. The performance was assessed by evaluating larval feeding oviposition preference, mandibular morphology, survival rates weight gain. Results showed mean rate 63% T3 compared 96% control. larvae fed leaves twice that those Si‐treated leaves. Likewise, incisor length significantly shorter (177 μm) than (447 μm). Moreover, less favourable egg laying, only 20% eggs laid them. These findings indicate supplementation enhances resistance infestation armyworm. This Si‐mediated against underscores potential sustainable chemical pesticides integrated strategies.

Nghiên cứu này tập trung vào việc khai thác tiềm năng ứng dụng của hạt nano silica (SiNP) trong bảo vệ thực vật, với mục tiêu cải thiện hiệu quả kiểm soát sâu, bệnh hại và tăng cường sức đề kháng cây trồng. SiNP được tổng hợp thông qua các phương pháp truyền thống như sol-gel, Stöber, ngưng tụ hơi hóa học quy trình xanh thân môi trường, cho phép điều chỉnh kích thước, cấu trúc tính chất vật liệu. Với vai trò một mang quả, hỗ trợ lưu giữ giải phóng có thuốc dựa trên yếu tố hoạt pH, enzyme, nhiệt độ, giúp kéo dài vệ, giảm thất thoát dư lượng trường. Ngoài ra, thể hiện khả nấm bệnh, vi khuẩn, sâu hệ phòng sinh lý phân tử cây, enzyme chống oxy hòa tín hormone vật. Tuy nhiên, vấn liên quan đến tồn đất tác động thái vẫn cần nghiên thêm để tối ưu nông nghiệp. tích xu hướng , đó góp phần xây dựng bền vững, thiểu cực trường sản xuất nghiệp bối cảnh biến đổi khí hậu an toàn phẩm.

Flavonoids contribute to fruit sensorial and nutritional quality. They are also highly beneficial for human health can effectively prevent several chronic diseases. There is increasing interest in developing alternative food sources rich flavonoids, nano-enabled agriculture provides the prospect solving this action. In study, triiron tetrairon phosphate (Fe7(PO4)6) nanomaterials (NMs) were synthesized amended soils enhance flavonoids accumulation tomato fruits. 50 mg kg-1 of Fe7(PO4)6 NMs was optimal dose based on its outstanding performance promoting accumulation. After entering roots, promoted auxin (IAA) level by 70.75 164.21% over Fe-EDTA control, then up-regulated expression genes related PM H+ ATPase, leading root proton ef-flux at 5.87 pmol cm-2 s-1 rhizosphere acidification. More Mg, Fe, Mn thus taken up into plants. Subsequently, photosynthate synthesized, transported fruits more rapidly increase flavonoid synthesis potential. The metabolomic transcriptomic profile further revealed that regulated sucrose metabolism, shi-kimic acid pathway, phenylalanine synthesis, finally enhanced biosynthesis. This study implies potential improve quality enhancing

Wound healing is a postharvest characteristic of potato tubers through accumulating suberin and lignin, which could reduce decay water loss during storage. This study aimed to explore the impact mechanisms sodium silicate on wound potatoes. After being wounded, "Atlantic" were treated with or 50 mM silicate. The results showed that treatment accelerated formation structures significantly reduced weight disease index tubers. Furthermore, induced genes expression enzyme activity phenylalanine ammonia lyase (PAL), 4-coumarate: coenzyme A ligase (4CL), cinnamyl alcohol dehydrogenase (CAD) involved in phenylpropane metabolism, enhancing synthesis main precursors polyphenolic (SPP) such as coniferyl alcohol, sinapyl alcohol. Meanwhile, gene StPOD StNOX was activated, production O2- H2O2 promoted, be used for injury signal transmission oxidative crosslinking SPP monomers lignin precursors. Besides, antimicrobial compounds, total phenolics, flavonoids also induced. We suggest promote by inducing deposition SPP, compounds

The exploration of environmentally friendly, less toxic, sustained-release insecticide is increasing with the growing demand for food to meet requirements expanding population. As a carrier, unique, friendly intelligent responsive hydrogel system an important factor in improving efficiency utilization and accurate release. In this study, we developed facile approach incorporating natural compound rosin (dehydroabietic acid, DA) zinc ions (Zn2+) into poly(N-isopropylacrylamide) (PNIPAM) network construct controlled-release carrier (DA-PNIPAM-Zn2+). Then, model avermectin (AVM) was encapsulated at drug loading rate 36.32% form AVM@DA-PNIPAM-Zn2+. Surprisingly, smart controlled exhibited environmental responsiveness, strongly enhanced mechanical properties, self-healing ability, hydrophobicity, photostability ensure balance between friendliness precision release experiments showed that carboxyl amide groups polymer chains alter intermolecular forces within meshes ingredient diffusion by changing temperatures (25 40 °C) pH values (5.8, 7.4, 8.5), leading different behaviors. insecticidal activity AVM@DA-PNIPAM-Zn2+ against oriental armyworms good, effective minimum toxicity toward aquatic animals. Therefore, delivery armyworms. We anticipate ecofriendly, sustainable, smart-response may broaden its possible applications agricultural sector.
