“…(2020) reported that NPs with positive charge showed the highest delivery efficiency into stomata and apoplastic space. Moreover, the uptake and translocation of NPs is also influenced by plant factors since several key parameters differ with plant species and development stages including (1) the contact area between plant and NPs based on plant morphological traits; (2) the amount of immature roots and leaves which are the major entrance of NPs into plants; (3) the equivalent pore sizes of physiological barriers such as cell wall, plasma membrane, cuticle, stomata, and vascular vessels) ( Tripathi et al., 2017 ; Lv et al., 2019 ; Dhakate et al., 2022 ). Overall, current literature is largely based on the determination and/or observation of NPs in plants, while the mechanisms of NPs uptake and translocation, especially at cellular and molecular levels, remain unclear and deserve further investigation.…”

“…In addition, Si/AgNPs (complex NPs of Si and Ag) also showed remarkable fungicidal and bactericidal effects against various plant pathogens such as Botrytis cinerea, Rhizoctonia solani, Pseudomonas syringae and Xanthomonas campestris (Park et al, 2006;Baka and El-Zahed, 2022). Furthermore, Khan et al (2022) reported that both SiNPs and titanium nanoparticles (TiNPs) inhibited the growth of Phomopsis vexans and Ralstonia solanacearum, while SiNPs induced a more prominent recuction of pathogen growth than TiNPs. As for insect pests, in a surface contact and feeding experiment, Ayoub et al (2017) found that SiNPs induced remarkable pesticidal effects in leafworm (Spodoptera littoralis), which was also influenced by their size and surface characteristics.…”

Silicon (Si) is a widely recognized beneficial element in plants. With the emergence of nanotechnology in agriculture, silicon nanoparticles (SiNPs) demonstrate promising applicability in sustainable agriculture. Particularly, the application of SiNPs has proven to be a high-efficiency and cost-effective strategy for protecting plant against various biotic and abiotic stresses such as insect pests, pathogen diseases, metal stress, drought stress, and salt stress. To date, rapid progress has been made in unveiling the multiple functions and related mechanisms of SiNPs in promoting the sustainability of agricultural production in the recent decade, while a comprehensive summary is still lacking. Here, the review provides an up-to-date overview of the synthesis, uptake and translocation, and application of SiNPs in alleviating stresses aiming for the reasonable usage of SiNPs in nano-enabled agriculture. The major points are listed as following: (1) SiNPs can be synthesized by using physical, chemical, and biological (green synthesis) approaches, while green synthesis using agricultural wastes as raw materials is more suitable for large-scale production and recycling agriculture. (2) The uptake and translocation of SiNPs in plants differs significantly from that of Si, which is determined by plant factors and the properties of SiNPs. (3) Under stressful conditions, SiNPs can regulate plant stress acclimation at morphological, physiological, and molecular levels as growth stimulator; as well as deliver pesticides and plant growth regulating chemicals as nanocarrier, thereby enhancing plant growth and yield. (4) Several key issues deserve further investigation including effective approaches of SiNPs synthesis and modification, molecular basis of SiNPs-induced plant stress resistance, and systematic effects of SiNPs on agricultural ecosystem.

“…Silicon fertilizer was listed as the fourth largest element fertilizer after nitrogen, phosphorus and potassium by the international soil community [ 8 ]. Silicon is the second most abundant element on the earth's surface [ 9 ], and some studies have shown that silicon can significantly improve the stress resistance of plants, protect crops from pathogen infection, improve the ability to resist fungal diseases, and enhance the toughness of plants, which is very beneficial to the healthy growth of crops[ 10 – 12 ]. Silicon element is non-corrosive and sustainable, and silicon fertilizer is considered to be environmentally friendly and sustainable agricultural fertilizer [ 13 ], which has been paid more and more attention in agricultural practice.…”

The application of nano fertilizers is one of the hotspots in current agricultural production. In this study, nano silicon materials were mixed with compound fertilizers to make nano silicon fertilizer. The effects of different amounts of nano silicon application on the breaking-resistance strength, lodging-resistance index, lignin accumulation, lignin synthesis related enzymes, and the relative expression of lignin synthesis related genes in the second stem node of wheat were mainly studied. Four treatments were set up: CK (750 kg·ha−1 compound fertilizer), T1 (750 kg·ha−1 compound fertilizer + 0.9 kg·ha−1 nano silicon), T2 (750 kg·ha−1 compound fertilizer + 1.8 kg·ha−1 nano silicon), T3 (750 kg·ha−1 compound fertilizer + 2.7 kg·ha−1 nano silicon). The results of the two-year experiment showed that the breaking-resistance strength, lodging-resistance index, lignin accumulation in the second stem node of wheat treated with nano silicon fertilizer were higher than CK. In the first year of the experiment, the lignin accumulation of T2 was 130.73%, 5.14% and 7.25% higher than that of CK, T1 and T3 respectively at the maturity stage. In the second year of the experiment, the lignin accumulation of T2 was 20.33%, 11.19% and 9.89% higher than that of CK, T1 and T3 respectively at the maturity stage. And the activities of PAL, 4CL, CAD, and related gene expression levels were also higher than CK. And among them, T2 performed the best, indicating that the application of nano silicon fertilizer is beneficial for improving the lodging resistance of wheat stems and is of great significance for improving the quality of wheat.

“…Furthermore, the use of nano-selenium was reported in different studies, e.g., against tomato leaf blight caused by Alternaria alternata [ 26 ] and against tomato late-blight disease [ 39 ]. Although nano-silicon has the potential for mitigating biotic stress in plants [ 40 , 41 ], more investigations are required. This includes nano-silicon’s effect against different diseases, such as stem canker; stem and leaf blight; leaf and root wilt; leaf spot; and soft rot [ 42 ].…”

Nanofungicides with Selenium and Silicon Can Boost the Growth and Yield of Common Bean (Phaseolus vulgaris L.) and Control Alternaria Leaf Spot Disease

et al. 2023

There is an urgent need to reduce the intensive use of chemical fungicides due to their potential damage to human health and the environment. The current study investigated whether nano-selenium (nano-Se) and nano-silica (nano-SiO2) could be used against the leaf spot disease caused by Alternaria alternata in a common bean (Phaseolus vulgaris L.). The engineered Se and SiO2 nanoparticles were compared to a traditional fungicide and a negative control with no treatment, and experiments were repeated during two successive seasons in fields and in vitro. The in vitro study showed that 100 ppm nano-Se had an efficacy rate of 85.1% on A. alternata mycelial growth, followed by the combined applications (Se + SiO2 at half doses) with an efficacy rate of 77.8%. The field study showed that nano-Se and the combined application of nano-Se and nano-SiO2 significantly decreased the disease severity of A. alternata. There were no significant differences among nano-Se, the combined application, and the fungicide treatment (positive control). As compared to the negative control (no treatment), leaf weight increased by 38.3%, the number of leaves per plant by 25.7%, chlorophyll A by 24%, chlorophyll B by 17.5%, and total dry seed yield by 30%. In addition, nano-Se significantly increased the enzymatic capacity (i.e., CAT, POX, PPO) and antioxidant activity in the leaves. Our current study is the first to report that the selected nano-minerals are real alternatives to chemical fungicides for controlling A. alternata in common beans. This work suggests the potential of nanoparticles as alternatives to fungicides. Further studies are needed to better understand the mechanisms and how different nano-materials could be used against phytopathogens.
