Opis:: The article is devoted to highlighting the results of field studies conducted during 2019–2021 on the influence of multifunctional growth-regulating drugs with a fungicidal effect Architecttm and Helafit Combi on the productivity and optimization of water consumption of high-oleic sunflower hybrids in non-irrigated conditions of the steppe zone of Ukraine. The study was carried out under non-irrigated conditions in the experimental field of the “Mykolaiv DSDS IZZ NAAS” state institution of Ukraine (GPS: 46.980168, 32.148075) on southern low-humus chernozems. The program of scientific research provided for the foundation of a two – factor field experiment, in which sunflower hybrids were studied, namely Hector and Oplot (originator-V. Y. Yuryev Institute of crop production); DSL403 and P64GE133 (manufacturer Corteva, Brevant) and 8X477KL (manufacturer Dow Seeds). In the experiment, multifunctional growth – regulating preparations of chemical origin, i.e. Architecttm, and biological origin, i.e. Helafit Combi, were used. They were introduced in the form of foliar treatments of sunflower hybrids in the Phase 6–8 of real leaves with a rate of 1 l/ha. The weather conditions in 2019–2021 can be classified as medium – arid, typical for this growing zone, but the most favorable year was 2021. As for the temperature indicators, the average monthly air temperature for the study years was higher than the corresponding long-term average data. The results of three-year field studies showed that foliar treatments of sunflower hybrids of high-oleic type with Architect and Helafit Combi multifunctional preparations had a positive effect on improving growing conditions and increasing plant resistance to stress from high temperatures and lack of moisture. The study preparations contribute to a more economical use of soil moisture for the formation of a crop unit, as evidenced by a decrease in the water consumption coefficient for all the studied hybrids. The lowest water consumption coefficient of 1283 m3/t was found in the P64GE133 hybrid under the conditions of treatment of sunflower plants with a Helafit Combi combined preparation of biological origin. Foliar treatment of plants with combined growth-regulating preparations led to optimization of water consumption of agrocenosis in general.

Opis:: The article is devoted to establishing the influence of multifunctional environmentally friendly growth-regulating preparations on the phytosanitary state of agrocenoses of various types of wheat varieties and their productivity under non-irrigated conditions of the steppe zone of Ukraine. Field studies were conducted over 2016–2020 in two agroclimatic points of the steppe zone: such as in the experimental field of the Kherson State Agrarian and Economic University (GPS: 46.743447, 32.481064 Kherson, Ukraine – point 1) and the land use of the farm "Svetlana" (GPS: 47.635522, 32.099772 Vossiyatskoye Village, Mykolaiv region, Ukraine-point 2) under non-irrigated conditions. The implementation of the scientific research program was carried out by laying three – factor experiments in these agroecological points, where Factor A was the varieties of winter wheat – Khersonska 99, Kirena, Askaniyska, Mudrist, Clarissa, Khutoryanka; variants of Factor B: growth-regulating preparations – VuksalMicroplant, Helafit Combi, Phytomare, without cultivation (control); variants of factor C: terms of sowing winter wheat – 10.09, 20.09, 30.09 and 10.10. Studies established that the use of multifunctional growth-regulating preparations helped to reduce the level of plant damage by pathogenic microflora at all sowing periods and varieties of winter wheat. Phytomare and Helafit Combi were the most effective in this respect, under various growing conditions. In most cases, they reduced the degree of damage to winter wheat plants by pathogenic microflora by 40–50% or more. All applied growth regulators increased the mass of grain from the ear and the mass of 1000 grains at different sowing times. It was found that for five years of field research, the greatest increase in yield under different research conditions and different varieties was shown by the Helafit Combi preparation. When it was applied in the experimental field of the Kherson State Agrarian and Economic University, the yield was additionally formed from 0.22 up to 0.5 t/ha, in the field of FG "Svetlana", respectively, it was formed 0.14 up to 0.36 t/ha.

Opis:: Kounis syndrome (KS) is an acute coronary syndrome developing as a consequence of an anaphylactic or allergic reaction. Multiple mediators (especially histamine) released by mast cells, platelets, and some immune cells may lead to coronary vasospasm or thrombosis and cause an acute coronary syndrome. A clinical case of the KS in a hospitalized patient being treated for the COVID-19-associated pneumonia is presented. A 62-year-old woman was treated for COVID-19-associated pneumonia. In 15 min after the beginning of the Moxifloxacin infusion, the patient complained of severe headache, crushing chest pain, abdominal pain, severe general weakness, shortness of breath. Hypotension and decrease in SpO2 developed. Immediately performed ECG showed the ST-segment elevation in leads I and aVL. There were reciprocal changes in leads III, aVF, V3-V6. Troponin I was slightly elevated. Coronary angiography showed no hemodynamically significant coronary artery lesions. The KS type 1 was diagnosed. Repeated ECG in 2 hours showed isoelectric ST segments in all leads. It may be difficult to diagnose KS. Clinical signs of an allergic or anaphylactic reaction should raise the suspicion of KS. Moxifloxacin as well as other fluoroquinolones may be associated with the development of KS. We suggest a possible association of COVID-19 with KS. However, this issue requires further observation.
