Pesticide nanoencapsulation and its foliar application are promising approaches for improving the efficiency of current pesticide practices, whose losses can reach 99%. Here, we investigated uptake translocation azoxystrobin, a systemic pesticide, encapsulated within porous hollow silica nanoparticles (PHSNs) mean diameter 253 ± 73 nm, following on tomato plants. The PHSNs had 67% loading azoxystrobin enabled controlled release over several days. Thus, nanoencapsulated was taken up distributed more slowly than nonencapsulated pesticide. A total 8.7 1.3 μg quantified in different plant parts, 4 days after 20 single leaf each plant. In parallel, (as Si particulate SiO2) were characterized. translocated 15.5 1.6 μg, rate patterns from their load. Notably, throughout plant, although they much larger known size-exclusion limits (reportedly below 50 nm) tissues, which points to knowledge gaps mechanisms vary significantly nanosilica-encapsulated formulations.

Lead (Pb) is a highly toxic contaminant that ubiquitously present in the ecosystem and poses severe environmental issues, including hazards to soil-plant systems. This review focuses on uptake, accumulation, translocation of Pb metallic ions their toxicological effects plant morpho-physiological biochemical attributes. We highlight uptake metal controlled by cation exchange capacity, pH, size soil particles, root nature, other physio-chemical limitations. toxicity obstructs seed germination, root/shoot length, growth, final crop-yield. disrupts nutrient through roots, alters plasma membrane permeability, disturbs chloroplast ultrastructure triggers changes respiration as well transpiration activities, creates reactive oxygen species (ROS), activates some enzymatic non-enzymatic antioxidants. also impairs photosynthesis, water balance mineral nutrients, hormonal status, structure permeability. provides consolidated information concentrating current studies associated with Pb-induced oxidative stress conditions various plants, highlighting roles different antioxidants plants mitigating Pb-stress. Additionally, we discussed detoxification tolerance responses regulating gene expressions, protein, glutathione metabolisms resist phytotoxicity. Overall, approaches tackle have been addressed; phytoremediation techniques biochar amendments are economical eco-friendly remedies for improving Pb-contaminated soils.

Abstract Incorporating green chemistry concepts into nanotechnology is an important focus area in nanoscience. The demand for metal oxide nanoparticle production has grown recent years. beneficial effects of using nanoparticles agriculture have already been established. Here, we highlight some potential antifungal properties Zizyphus spina leaf extract-derived copper (CuO-Zs-NPs), produced with a spherical shape and defined 13–30 nm particle size.
