“…[ 49 ] It was demonstrated that the foliar‐spraying of soybean‐plants with different concentrations of MgONPs increased the contents of soluble proteins and sugars. [ 40 ] Also, both soluble carbohydrate and protein contents of horse gram ( Macrotyloma uniflorum ) were significantly accumulated when the mentioned plants exposed to MgONPs as compared to the control (untreated) plants. [ 41 ] Magnesium plays a significant role in enhancing plants’ growth and differentiation as it being a central ion in the structure of chlorophyll as well as contributes to carbon dioxide fixation for photosynthesis, chlorophyll synthesis, sugar, and protein formation, and so on.…”

Recently, agricultural management innovation has incorporated engineered nanoparticles. The current investigation was carried out to produce magnesium oxide nanoparticles (MgONPs) for the first time applying S. cerevisiae extract. FTIR, XRD), HRTEM, and zeta potential analysis were used to characterize the MgONPs. The FTIR data show that the bioactive substances reduce and cap the synthesized MgONPs. The crystalline metallic MgONPs had four significant peaks in the XRD pattern. The size and form of MgONPs were validated by TEM, which exhibited spherical structures with an average size of 27 nm. The effect of various dosages of MgONPs administered to the cowpea (Vigna unguiculata L.)plant on all in‐vitro parameters was shown to be significant in the study. The concentration 200 ppm was the most significant treatment which increased shoot length, shoot dry‐weight and root dry‐weight by 27.35%, 45.09% and 31.91% when compared with the untreated cowpea plants. MgONPs significantly increased photosynthetic pigments, with 150 ppm treatment significantly increasing soluble proteins and carbohydrates. MgONPs effectively treated cowpea C. maculatus, with dose and time‐dependent insecticidal activity. MgONPs death rates varied by 82.66% and 100% on fifth day. Biochemical and histopathological studies of rats were investigated. Rats treated with MgONPs showed higher GOT, GPT, Urea levels, but lower creatinine, indicating significant differences. MgONPs‐treated rats' liver showed mild to moderate histopathologic changes, including portal blood vessel congestion, lymphocytic cholangitis, and degenerative changes. MgONPs has the potential to improve cowpea development outcomes and suppress grain insects (C. maculatus).This article is protected by copyright. All rights reserved

“…The current results revealed that the higher concentrations (200 mg/L) of MgONPs negatively affected peroxidase activity. These results are supported with previously reported by Ramadan et al (2020), who found that soybean plants sprayed with a higher concentration of 40 mg L -1 MgONPs, exhibited a low value of peroxidase activity. Conversely, Cai et al (2018a), found that exposure of tobacco plants to 250 μg/mL of MgONPs enhanced the activity of peroxidase.…”

Powdery mildew disease of peppers (Capsicum annuum L.) caused by Oidiopsis sicula is the most damaging disease in the field and greenhouse. Chemical control has been widely used for the control of powdery mildew. To minimize the deleterious impacts of fungicides, the present study aimed to evaluate the antifungal effect of different concentrations (100, 150 and 200 mg/L) of MgONPs and ZnONPs against powdery mildew in comparison with the conventional fungicide penconazole (0.25 ml/L) under greenhouse conditions. The synthesis and characterization of MgO and ZnONPs were carried out. Dynamic light scattering (DLS) analysis revealed the presence of MgONPs and ZnONPs at the nanoscale level with a size average of 52.97 nm ± 1.43 S.D and 79.45 nm ± 1.74 S.D, respectively. Two foliar sprays were applied at two-week intervals on pepper plants cv. Dolma, naturally infected with powdery mildew in the three greenhouses of El -Dokki (GH-1), Toukh (GH-2) and El-Haram (GH-3). Both MgONPs and ZnONPs markedly reduced disease severity (DS) and area under the disease progress curve (AUDPC) at a concentration of 200 mg/L. Statistical analysis showed a significant (p<0.05) difference between treatments in the three greenhouses as well as between means of combined treatments. Scanning electron micrographs confirmed that MgONPs and ZnONPs caused inhibition and alterations in the treated fungal structures. Pepper plants treated with penconazole displayed the highest peroxidase activity and recorded 1.229 ΔA422/10 sec/g FW. While, the highest polypheneloxidase activitiy was obtained by MgONPs with value reached 0.283 ΔA495/10 sec/g FW . Out of all treatments, MgONPs were the superior in increasing total chlorophyll at the three applied concentrations, with values of 74.81, 82.94, and 91.19 mg/g FW, respectively. Cytotoxic investigations exhibited the clastogenic nature of MgONPs, ZnONPs, and penconazole. The obtained results are encouraging and emphasize the recognition of MgONPs and ZnONPs as a viable alternatives to conventional strategies.

“…In this concern, highest phenol content was recorded with treatment of MgONPs at 200 mg/L, which showed decrease trend with decreasing concentration. However, Ramadan et al (2020) documented that the highest phenol content was obtained by lower concentration 20 ppm of MgONPs. Abdel-Wahab et al (2019) demonstrated that lower concentrations 50, 100 and 150 mg/L of CuONPs increased phenolic compounds in callus cells of Solanum nigrum, while the higher concentration of 200 mg/L significantly decreased it.…”

Black scurf disease caused by Rhizoctonia solani is common on potato crop worldwide. The current study aimed to evaluate the antifungal activity of CuONPs and MgONPs on R. solani in laboratory, greenhouse and field trials. Field trials were conducted under naturally infected fields located in two Governorates, Behera and Menoufia. Potato tubers cv. Spunta were soaked in different concentrations (75, 150 and 200 mg/L) of the tested NPs for 2 hours pre-planting. Disease severity (DS) and disease incidence (DI) of black scurf symptoms on the harvested potato tubers were estimated. Ultrastructural changes in R. solani hyphae in response to the tested NPs were also detected using Transmission Electron Microscope (TEM). Physiological and biochemical activities were also determined in potato leaves after 20, 40 and 60 days of planting. In vitro results showed that MgONPs at 200 mg/L exhibited the greatest inhibitory effect on the mycelial growth of R. solani, with inhibition reached 73.47 %. Ultrastructural micrographs of TEM images of R. solani hyphae confirmed the damage induced by NPs. Greenhouse results exhibited that the great reduction in DI and DS% was achieved by MgONPs at concentration 200 mg/L, with efficacy reached 85.07 and 93.47 %, respectively. The same trend of greenhouse results was observed, of which MgONPs at concentration 200 mg/L, had significant (p<0.05) effect in reducing both DI and DS% in both Menoufia and Behera field trials. Also, MgONPs had a significant (p<0.05) effect in increasing the yield of potato tubers in both field trials. NPs had great impact in increasing enzyme activities, phenols and chlorophyll content when compared to untreated control plants. Energy Dispersive X-ray Spectrometry (EDX) analysis confirmed the presence of CuONPs in the tissues of treated harvested potato tubers compared with the control. The accumulation of CuONPs in edible plant tissues is a critical issue that could impact human health, and this should be taken in consideration when establishing control program for black scurf disease.
