“…In the same year (2011), a Dividend Extreme efficiency study with a slightly higher rate (0.8 l/t) on filter paper rolls was conducted. The biological effectiveness of this fungicide was 100% (Polunina et al, 2017). The phytotoxic effects of fungicides were shown in many scientific studies.…”

The microbiota of winter wheat seeds from the North-East of Ukraine was studied by a biological method. Its considerable variability is established over three years (2017–2019). The effect of the treatment agents on most microorganisms of wheat seed microbiota in Ukraine, rather than on its genera and species, is shown. It has been proven that fungicides deleted some species and did not affect the development of others. Chemicals replaced some species or genera of fungi with others or even other microorganisms. Biological seed treatment (Phytosporin-M) has caused less microbiota change than chemical treatment (Maxim 0.25 FS, Rostock, Kinto Duo). Fungicides have replaced the dominance of Alternaria spp. (2017 – 57.8%, 2018 – 63.5%) for the dominance of yeast (Rostock – 54%) and Aureobasidium pullulans (Maxim 0.25 FS – 84.2%) in 2017, bacteria (Maxim 0.25 FS – 72.3%, Rostock – 53.8%) – in 2018. A. pullulans dominated in the microbiota of winter wheat seeds in 2019. The highest amount of A. pullulans was noted for the treatment of seeds by Phytosporin-M (85.9%). The biological seed treatment reduced the amount of Nigrospora spp. and Alternaria spp. Several times (3 and 5, respectively), chemical agents did not give Nigrospora spp. germination reduced the amount of A. pullulans, Alternaria spp. in 2019. Maxim 0.25 FS, Rostock 50%, and Kinto Duo delayed seed germination and seedling development on agar medium and soil, whereas Phytosporin-M – on the contrary, promoted the growth of seedlings and significantly exceeded control.

The article considers the need to analyze the most important factors of the external and internal environment. The article is devoted to the external and internal environment of the company when choosing a supplier. The main factors influencing the activity of enterprises are singled out. It is determined that the study of the external and internal environment of the company is a tool to identify possible threats to the organization. The study of the external and internal environment allows the company to predict possible situations in a timely manner, develop an action plan in case of negative moments, formulate a strategy that will allow the company to achieve its goals and prevent possible losses. The main definitions are considered and methods are proposed that can be used in the system of strategic analysis. The article focuses on the issues of enterprise research through SWOT and PEST analyzes, which are used to make a strategic decision, and also helps to determine the advantages and disadvantages, which will assess the need for these methods and highlight the points that require improvement of the company when choosing a supplier. It is concluded that there is a need for increased attention to the analysis of the external and internal environment, as well as the importance of internal analysis of all the main components of research mechanisms.

The increase in the yield capacity of cereal spike crops under the current change of the climatic conditions in Ukraine will have a positive tendency in the nearest future. However, sustainable grain production under sharp weather fluctuations is possible only with the agro-technological systems' improvement. The pre-sowing seed treatment with chemical synthesis pesticides remains the primary method in the agricultural industry today. However, pesticides inevitably have a negative influence on the ecosystem of any level. A more environmentally friendly seed treatment method under the intensive technology is the combination of microwave seed irradiation and seed incrustation with the plant growth regulators that increase the cereal crops' yield capacity up to 15–20 %. It is possible to reduce the negative influence of chemical measures on the quality of the cereal crops seeds by using for the seed treatment a mixture of a treatment agent with the preparations having the stimulating properties. The most promising among all physical methods of the pre-sowing seed treatment is the microwave technology, which suppresses the entire complex of the seed infection and can become an alternative to the chemical method of plant protection. The universal character and practical importance of MW technologies combined with the growth-regulating substances consist not only in the increase in the yield capacity of the field crops but also in reducing the technogenic load on the environment. The peculiarity of EMF of EHF application in agricultural production is the necessity to consider the crops' specific electro-physical, technological, and biological properties. High heterogeneity greatly influences the electromagnetic action energy and the final result.
