In the 21st century, sustainable agriculture is expected to become a major contributor food security and improved nutrition. Amine–epoxide-based materials have great potential for use in due their tunable physicochemical features, which are dependent on concentration composition of monomers. this work, catalyst-free green synthesis, using only water as solvent, was performed obtain nanocarrier (TGel) capable transporting nutrients after seed priming. The synthesis based opening epoxy ring by nucleophile attack, an amine-terminated polyether. Transmission electron microscopy (TEM) dynamic light scattering (DLS) techniques showed spherical morphology particles, ranged size from 80 nm (unloaded TGel) 360 (zinc-loaded TGel), respectively. Theoretical bonding analysis revealed that Zn cation species ZnSO4 source interact with polymer via σ-bonds, whereas EDTA forms hydrogen bonds polymer, thereby enhancing noncovalent interactions. Micro X-ray fluorescence (μ-XRF) energy-dispersive spectroscopy (EDXRF) provided details distributions compartments shoots cucumber plants priming plant growth, Zn-loaded TGels did not affect physiology plants, indicated photosynthetic efficacy, chlorophyll, anthocyanin indices.

Polymeric systems can facilitate the diffusion of micronutrients through seeds, offering an innovative and sustainable way to improve plant health increase food production. In present work, a polymeric nanogel based on polyether-POE-diamine bisepoxide was synthesized in-depth characterized, encompassing its morphological characteristics (by Transmission Electron Microscopy, TEM), size distribution, surface charge particles dynamic light scattering, DLS zeta potential, ζ). The formation network assessed using Fourier-transform infrared spectroscopy (FTIR) proton nuclear magnetic resonance (1H NMR), confirming opening epoxide ring amine glycol groups. effects seed priming with (well-defined spherical particles, sizes around 120 nm, named POE-gel) early growth stage cucumber plants (Cucumis sativus) exhibited discernible ameliorative impact root shoot lengths, average improvements 33% 90%, respectively, compared control group after 12 days. Extensive investigation germination assays micro X-ray fluorescence (μ-XRF) analysis indicated potential applications POE-gel as carrier for (such Fe3+). seeds treated iron-loaded presented substantial positive effect length, exhibiting 3-fold in control-Fe treatment at same concentration. loaded effectively penetrated compartments, providing even distribution iron ions facilitating uptake nutrients (K, Mn, Zn) by seeds. Toxicological zebrafish (Danio rerio), leaves revealed notable safety unloaded agricultural purposes. Employing water only solvent synthesis, well eliminating use catalyst, makes this class suitable applications. findings work contribute development agriculture, presenting approach enhancing nutrient application nanogels technology.

Utilization of biodegradable carrier-based nano herbicide formulations for sustainable weed management in agriculture

Frontiers in Agronomy, Journal Year: 2024, Volume and Issue: 6

Published: Nov. 27, 2024

Recently, the injudicious use of herbicides in agriculture is causing numerous hazards that affect environment and living organisms. To achieve SDG 2030 agenda goal 12- “Ensure sustainable consumption production patterns,” there an urgent need to shift towards using toxic-free agricultural inputs. Various techniques are widely adopted control weed growth development, but farmers mostly rely on herbicide application. Nanotechnology-enabled formulations more efficient than traditional sources. The nanoherbicides enable lesser application frequency minimum quantity requirement, thereby preventing accumulation soil water bodies. Mainly nano-mediated biodegradable carrier-based possess properties prolonged release, targeted inhibition, reduced mobility soil, better adhesion plant surface, retards rapid degradation active ingredients (AIs), which increase efficiency against weeds. Biodegradable carrier materials cost-effective readily available from living/non-living organisms mineral sources, can be alternate source for metal/metal-oxide materials. Materials like chitosan, derivatives, clay particles, synthetic polymers notable reported encapsulating or loading molecules. Applying innovative methodology controlling weeds while considering environmental safety. This review focused mainly recent advances mitigate crisis management. ultimate objective this manuscript serve as a reference material exploring nano-based formulations, their mobility, fate, future perspectives.
