“…Recent studies have shown that in the fi ght against viral infections, a promising direction in the fi eld of potato technology is the use of nanotechnology, as well as the combined use of nanoparticles in combination with microbial preparations [4]. Th us, the multi-component microelement preparation «Avatar-2 protection» and the combination of the preparation «Azogran» with the composition of Se+1 nanoparticles signifi cantly reduced the frequency of detection of viral diseases [5].…”

“…Th e results of our research are consistent with the data obtained by other authors, who proved the eff ectiveness of the use of the microbial preparation Azogran for combating bacterial, fungal, and viral diseases of potatoes, increasing the marketability of tubers and yield. Th e authors believe that the composition of Se+1 nanoparticles and the preparation Azogran positively aff ected the microbiota of the potato rhizosphere and the physiological state of the plants [4,5]. When Azogran is introduced into the root system of vegetable and technical crops, the nitrogen and phosphorus nutrition of plants improves, their growth and development are signifi cantly stimulated, and productivity increases by 18-37% [22].…”

The problem of increasing the yield of cultivated plants attracts the attention of specialists and prompts scientists to study viral plant diseases as one of the causes of significant crop losses. A virus is an endogenous parasite that, having entered plant cells, uses the functions of cell organoids and biosystems for its reproduction, which leads to plant disease and a decrease in their productivity. One of the promising approaches to reducing viral damage to plants is the use of microbial antiviral preparations. The complex bacterial preparation Azogran, developed at the Institute of Microbiology and Virology of the National Academy of Sciences of Ukraine, is based on the interaction of phosphate-mobilizing bacteria Bacillus subtilis IMV B-7023, nitrogen-fixing bacteria Azotobacter vinelandii IMV B-7076, and clay mineral — bentonite. Phosphate-mobilizing bacteria and nitrogen-fixing bacteria significantly improve the growth and development of plants, essentially increasing the yield of agricultural crops. However, the effect of Azogran on the development and yield of potato plants infected with the X-virus has not been sufficiently studied. Taking this into account, the aim of the work was to study the effect of the complex bacterial preparation Azogran on the growth, some physiological and biochemical properties, and productivity of potato plants, uninfected and infected by the potato virus X. Methods. Microbiological (obtaining the bacterial preparation Azogran, used in granular form (0.25 g)), virological (isolation of potato virus X, inoculation of plants with potato virus X), serological (testing for the presence or absence of the virus), biochemical (determination of chlorophylls a, b and carotenoids), spectrophotometric, and statistical analysis. Results. In the conducted experiments, the Azogran was used in granular form in the amount of one and two granules. The effectiveness of the use of the preparation, which stimulates the intensive growth of plants of two varieties of potatoes (early variety Spokusa and medium variety Diva), which leads to an increase in their yield, is shown. The positive effect of Azogran was observed on the development of both infected and non-infected plants. It was found that when two granules of the preparation were applied, the yield of potatoes of the Diva variety increased by 27.02%, and the yield of potatoes of the Spokusa variety under the same conditions increased by 29.46%. A similar effect of Azogran was observed on plants infected with the potato virus X, only to a lesser extent: in the Diva variety, the yield was 16.3% higher compared to the control (control — plants not infected by the virus), and in the Spokusa variety it was higher by 22.59%. When studying the content of chlorophylls a and b and carotenoids in virus-infected potato plants, it was established that the content of chlorophylls at different stages of virus infection was different, but the content of chlorophylls and carotenoids was higher in plants bacterized with Azogran. Conclusions. The complex bacterial preparation Azogran has a positive effect on the development of uninfected and infected plants, reducing the harmfulness of viral infections and contributing to the increase in potato productivity. Azogran can be successfully used in crop production to increase the quality and quantity of crop yields.

If it is necessary to reduce the anthropogenic impact on agroecosystems in conditions of constant increase in the cost of resources – improving the technology of growing corn through the use of nanotechnologies is one of the prerequisites for increasing the yield of crops and their profitability. In this regard, the purpose of the study was to investigate the biological activity of Zn nanocarboxylates and MoS2 nanoparticles at different concentrations for the germination, growth, and development of corn seedlings. An experiment was conducted on corn sprouts to determine the effect of Zn and MoS2 nanoparticles. The germination rate and germination energy of seeds under the action of nanoparticles were determined in accordance with the requirements of the state standard DSTU 4138-2002. The study results were analysed by generally accepted statistical methods. It was established that MoS2 nanoparticles when diluted at 1:10,000 (at a concentration of 700 mcg/l) show biological activity and cause an increase in the length of leaf blades and the length of the roots of corn seedlings by 35.0% and 100.0%, respectively. At other concentrations (1:100; 1:1,000) of Zn and MoS2 nanoparticles, no significant effect on the size of leaf blades and roots was observed. According to the results of the Mana-Whitney test, in all variants, with the exception of the action of MoS2 nanoparticles in a 1:10,000 dilution, the significance level of changes was not sufficient. Only in the variant with MoS2 at 1:10,000 dilution, an increase in root length was statistically significant. There was no statistically significant effect in all the studied variants on the germination energy and laboratory germination of maize seeds. The practical value of the study is to assess the effect of drugs (Zn nanocarboxylates and MoS2 nanoparticles) for foliar top dressing, a wide range of which is offered to agricultural producers, selection of effective concentrations for the growth, development, and yield of corn per grain
