“…On the other hand, our results showed that zeta potential was of 51.1 mV for synthesized Cu/Zn-NPs from P. juliflora suggested less layer stability formed on the surface of this NPs and functional groups of P. juliflora. Similar results was reported by Ruiz-Romero et al [12] who found positive values of zeta potential for Ag-NPS from Yucca shidigera indicating less stability and thus tendency to agglomerate and form large particles. Our results showed that the SEM measured size (74.33 to 59.46 nm) was considerably shorter than DLS size (334 nm).…”

“…The zeta potential and average hydrodynamic size of Cu/Zn-NPs was determined by Dynamic Light Scattering (DLS) in the range of 0.1-1000 µm at 25°C, using a nanotrac wave instrument (Microtrac) according to Ruiz-Romero et al [12]. For EDS analysis, the Cu/Zn-NPs were drop coated on to carbon film and analyzed using instrument Bruker Quantax 400.…”

Phenacoccus solenopsis has been recognized as an aggressively invasive species on cotton plants in different countries. This study was conducted to investigate the effect of green synthesized Cu/Zn-nanoparticles using aqueous leaf extract of Prosopis juliflora (mezquite) against P. solenopsis. The scanning electron microscope (SEM) showed bimetallic nanoparticles of Cu/Zn-NPs with spherical shape with varying size of 74.33 nm to 59.46 nm. More than 30% mortality of P. solenopsis was observed with Cu/Zn-nanoparticles (100 ppm) at 96 hours after treatment. Negligible mortality of P. solenopsis was recorded with Cu/Zn solution (100 ppm) and aqueous P. juliflora extracts. The results of the viability test for Cu/Zn-nanoparticles of P. juliflora showed a significant reduction of the cell viability by 50% in insect exposed to Cu/Zn-nanoparticles-P.juliflora. Therefore studies about nanotoxicity of Cu/Zn-NPs of P.juliflora are needed to reveal the mechanism of toxicity this phytonanoparticles in P.solenopsis.

“…Moreover, AgNP concentrations from 2.5 mg L −1 drastically reduce the germination of spores. Recently, Ruiz-Romero et al (2018) used AgNPs to inhibit the radial growth of two phytopathogenic fungi ( Fusarium solani and Macrophomina phaseolina ). However, this work only mentions that the AgNPs supplemented were obtained as an extract from Yucca ( Yucca shilerifera ), without reporting the AgNP concentration.…”

30Contamination by fungi and bacteria during the in-vitro propagation of plants leads to considerable losses of biological 31 material and precludes phytosanitary certification. The anti-microbial effect of silver nanoparticles (AgNPs) may be 32 an alternative for the eradication of in-vitro contaminants. This study evaluated the microbicidal activity of AgNPs on 33 a recurrent fungus during the micropropagation of stevia (Stevia rebaudiana Bertoni). First, the fungus was isolated 34 and identified at a molecular level by the sequencing and analysis of the ITS4/ITS5 rDNA region. The results of the 35 phylogenetic analysis of various fungi species showed that the strain under study (16-166-H) belongs to the genus 36 Sordaria and is 86.74% similar to S. tomento-alba (strain CBS 260.78). Subsequently, the inhibition of the growth of 37 S. tomento-alba was tested under different concentrations of AgNPs (0, 25, 50, 100, and 200 mg L -1 ), observing that 38 50 and 100 mg L -1 achieve ca. 50% growth inhibition (IC 50 ), while 200 mg L -1 produces a drastic inhibition. On the 39 other hand, the shape and size of AgNPs was examined using transmission electron microscopy (TEM), and the 40 transport and accumulation of AgNPs in S. tomento-alba cells were monitored through multiphoton microscopy. The 41 morphological and fluorescence analyses showed that AgNPs display different sizes, with larger nanoparticles retained 42 in fungal cell walls while smaller AgNPs penetrate into fungal cells. Probably, apoplastic and symplastic mechanisms 43 involved in the accumulation and transport of AgNPs affect the metabolic processes of the fungus, thus inhibiting its 44 growth. These results suggest that AgNPs possess antifungal activity and can be used in the eradication of contaminants 45 during the in-vitro culture of plant species.46 47

Today, green nanotechnology has great importance due to the presence of different modes of restrictive action against various pathogens such as fungi and bacterial species. The use of nanomaterials has recently increased in agriculture and plant-tissue culture thanks to their unique different properties such as; magnetic, electrical, mechanical, optical, and chemical properties. Optimum use of iron increases protein content in the wheat grain. They also enhance plant growth by improving disease resistance and increase stability of the plants by anti-bending and deeper rooting of crops. It has been reported by many researchers that Nano-fertilizers significantly influenced the seed germination which demonstrated the effect of Nano fertilizers on seed and seed vigor. Chemical methods have been used for the synthesis of nanoparticles. Developing Nano-biotechnology is generating interests in research towards eco-friendly, cost effective and biological synthesis of nanoparticles. Nanoparticles systems have been combined into plant fungal disease controlpractices. Using nanoparticles as biosensors in plant disease diagnostics is also illustrated.
