“…In studies with Candida glabrata it has been found that SeNPs attach and agglomerate on the surface of cells, cause loss of membrane’s smoothness, appearance of bulges and impairment of membrane’s integrity [ 124 ]. Vasylchenko and Derevianko [ 125 ] reported the strong antifungal activity of Selenium and iodine nanoparticles against Fusarium spp. Strong antifungal activity of green synthesized SeNPs was reported by Hashem et al, [ 126 ] Moreover, Lashin et al [ 127 ] confirmed SeNPs that biosynthesized from Ziziphus spina-christi exhibited antifungal activity against unicellular and multicellular fungi.…”

Plant extract-based green synthesis of nanoparticles is an emerging class of nanotechnology that has revolutionized the entire field of biological sciences. Green synthesized nanoparticles are used as super-growth promoters and antifungal agents. In this study, selenium nanoparticles (SeNPs) were synthesized using Melia azedarach leaves extract as the main reducing and stabilizing agent and characterized by UV–visible spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), energy-dispersive X-ray (EDX), and fourier transform infrared spectrometer (FTIR). The green synthesized SeNPs were exogenously applied on Mangifera indica infected with mango malformation disease. The SeNPs at a concentration of 30 μg/mL were found to be the best concentration which enhanced the physiological (chlorophyll and membrane stability index), and biochemical (proline and soluble sugar) parameters. The antioxidant defense system was also explored, and it was reported that green synthesized SeNPs significantly reduced the biotic stress by enhancing enzymatic and non-enzymatic activities. In vitro antifungal activity of SeNPs reported that 300 μg/mL concentration inhibited the Fusarium mangiferae the most. This study is considered the first biocompatible approach to evaluate the potential of green synthesized SeNPs to improve the health of mango malformation-infected plants and effective management strategy to inhibit the growth of F. mangifera.

Aim. Study the effect of Rise P® biological product, pesticide Celest Top, fungicide Quadrison on the growth, development, productivity and infestation of seed potato tubers with rhizoctonia. Methods. Field, measuring, weight, statistical. Results. Scientific studies have established the effectiveness of Rise P® biological product (Bacillus amyloliquefaciens (strain IT45)), pesticide Celest Top, fungicide Quadris for seed potatoes growing. The yield of seed potato of Skarbnytsia variety of superelite class in the variant with the treatment of planting material with Rise P® (450 g/t) increased by 3.3 t/ha or 8.9%. The combination of treatment of tubers with Rise P® and pesticide Celeste Top (0.7 l/t) contributed to an increase in potato yield relative to the control variant by 3.7 t/ha (9.9%), relative to the variant with the application of the pesticide of chemical origin – Celest Top, an increase in yield by 1.8 t/ha or 4.8% was observed. Application of Celest Top + Quadris (3.0 l/ha) provided an increase in yield to the control variant by 2.5 t/ha (6.7%). The treatment with tank mixtures of Celest Top + Rise P® + Quadris resulted in a yield increase of 4.0 t/ha (10.8%) compared to the control variant. Conclusions. The application of Rise P® biological product contributed to the growth of the overall yield and productivity of the basic seed potatoes of Skarbnytsia variety and reduction of tuber damage by rhizoctonia. Treatment of potato planting material with Rise P® biological product at the application rate of 450 g/t provided 4.3% of weakly affected tubers and 1.3% of tubers with a surface covering more than 10%, with infestation on the control variant without treatment of tubers with weak damage 14.0% and with a strong damage – 6.7%, which meets the norms of national legislation – “Methodological requirements in the field of seed production to preserve the varietal and sowing qualities of seed potatoes”, the order of the Ministry of Agrarian Policy and Food of Ukraine of July 12, 2019 No. 384. The permissible degree of tuber infection by Rhizoctonia (for tuber surface infestation over 10%) is 5.0%.
