Nanotechnology is a young branch of the discipline generated by nanomaterials. Its development has greatly contributed to technological progress and product innovation in field agriculture. The antimicrobial properties nanoparticles (NPs) can be used develop nanopesticides for plant protection. Plant diseases caused bacterial fungal infestations are main types crop diseases. Once infected, they will seriously threaten growth, reduce yield quality, affect food safety, posing health risk humans. We reviewed application metal-based inhibiting pathogenic bacteria fungi, discuss antibacterial mechanisms from two aspects: direct interaction between pathogens, indirect effects inducing resilience disease. © 2022 Society Chemical Industry.

Published: July 21, 2023

Agricultural nanotechnology has become a powerful tool to help crops and improve agricultural production in the context of growing world population. However, its application can have some problems with development harvests, especially during germination. This review evaluates nanoparticles essential (Cu, Fe, Ni Zn) non-essential (Ag Ti) elements on plant In general, effect depends several factors (dose, treatment time, method, type nanoparticle plant). addition, pH ionic strength are relevant when applying soil. case element nanoparticles, Fe show better results improving nutrient uptake, germination, possibility magnetic properties could favor their use removal pollutants. Cu Zn they be beneficial at low concentrations, while excess presents toxicity negatively affects About elements, both Ti Ag helpful for uptake. potential effects depend highly crop type, particle size concentration. Overall, agriculture is still early stages development, more research needed understand environmental public health impacts.

Introduction . Zinc is one of the essential micronutrients for living organisms; so, right performance several enzymes depends on this element. This micronutrient a regulator phytohormones and chlorophyll synthesis, also, it an element carbohydrates’ metabolisms in plants. Considering relatively high solubility ZnO‐NPs also ability plants to uptake accumulate these nanoparticles their biomass, can be used as effective nanofertilizer plants’ growth. Methods In present study, zinc oxide synthesized using chemical method effect (as nanofertilizer) seeds’ germination, seedlings’ rootlet, plumule, seedling’s vigour index two oilseed crops from Brassicaceae family, including Brassica napus L. Camelina sativa , were investigated. After treating seeds with different concentrations (from 0.1 1000 ppm) 6 days, germination percentage (GP) each treatment was measured. Results The results indicated increase GP both treated 10 ppm ZnO‐NPs. For B. napus, maximum occurred 5 which showed 30% compared control condition. observed concentration 15% test, germinated seedlings planted Hoagland hydroponic solution again week. species, great rootlet growth, while effects treatments plumule negligible. length 32% parameter contrast, toxic rootlets. 41% decrease 50 seedlings. Similar 1 ZnO‐NPs, rootlets’ observed, 68% study potential low (lower than ppm). addition, suggest toxicity species higher ppm.

Eco-toxicological estimation of cadmium induced damages by morpho-physiological and cellular response could be an insightful strategy to alleviate negative impact Cd in agricultural crops. The current study revealed novel patterns Cd-bioaccumulation mechanism opted alfalfa acquire tolerance under various soil applied zinc oxide nanoparticles (nZnO) doses (0, 30, 60, 90 mg kg-1), combined with 2% biochar (BC). Herein, the potential these amendments was justified decreased increased Zn-bioaccumulation into roots 38 % 48 shoots 51 72 respectively, co-exposure nZnO BC. As, transmission electron microscopy (TEM) scanning energy dispersive spectroscopy (SEM-EDS) ultrastructural observations confirmed that Cd-exposure stomatal closure, caused damage leaves ultrastructure as compared control group. On contrary, above-mentioned traits were reversed a higher dose, further aggravated adding BC along nZnO. Furthermore, levels efficiently alleviated Cd-mediated reductions biomass, antioxidant enzymatic response, gaseous exchange than control. Overall, application kg-1 (2 %) impactful averting stress ensuring better plant performance. Thereby, applying emerge promising green remediation techniques enhance crop Cd-polluted soil.

It is widely accepted that deficiency of macro (nitrogen) and micronutrients (zinc, copper etc.) affects the plant growth development which cause a significant threat to crop production food security. The Indian Farmers Fertilizer Cooperative (IFFCO) developed nano-urea (nano-N), nano-zinc (nano-Zn), nano-copper (nano-Cu) liquid fertilizer formulations enhance yields, simultaneously addressing nutrient deficiency, without causing toxicity. Therefore, this study was formulated evaluate effectiveness nano-N (nano-urea), nano-Zn, nano-Cu at varying N levels [0, 50, 75, 100% recommended rates nitrogen (RRN)] on maize-wheat pearl millet-mustard systems during 2019–20 2020–21. results exhibited application + nano-Zn with RRN significantly higher grain yields in maize (66.2–68.8%), wheat (62.6–61.9%), millet (57.1–65.4%), mustard (47.2–69.0%), respectively, over absolute control plots combinations three nano-fertilizers like applied plots. This mainly attributed Zn uptake by crops. However, 75% also produced comparable yields. Thus, applying via foliar applications, conjunction conventional urea, has potential reduce required amount up 25%, while maintaining equivalent yield levels. Similarly, registered profitability, soil mineral N, dehydrogenase activity (DHA), microbial biomass carbon (SMBC), both years. further research field trials nano fertilizers alone or combination are essential fully unlock its benefits ascertain long-term effects may offer pathway more efficient eco-friendly nourishment.
