In the conditions of dynamic climate changes, when growing periods are increasingly characterized by uneven distribution of precipitation efficiency, efficiency of root fertilizers, which are used in traditional systems of fertilizer crops, falls sharply. Thus, the use of sophisticated, physiologically balanced forms of micronutrients for foliar feeding is an alternative to correct the imbalance of mineral nutrition of plants. At the domestic market, there is a wide range of new agrochemical products, which differ by their composition and effect on plants. This article shows results of the study on the influence of micronutrients, produced at the LLC «Factory of Agrichemicals» (the Avangard R Fruit and Berries (A), the Avangard Kremnij Bio, marka A (AK), and compatible fungicides Strazh, Dzhek Pot (f)) on productivity of the plants of Fragaria ananassa Duch. In the scheme of the experience, the researchers used 2 varieties of strawberries: Elsanta and Florence. The variant without fertilizer and fungicide was accepted as a control. The highest pathogenic deterrent effect was observed in both varieties on the variants with application of tank mixtures (A + f, AK + f): Botrytis lesions at the level of 2–4 %, as compared to 8–16 % in the control. A significant excess of the yield has been noted at all tested versions of both varieties. The highest yield of both varieties is noted in the variant A + f, in particular, of the Florence variety, where the excess was up to 40.9 %, and for Elsanta variety the excess was 35.4 %. Therefore, all options of the micronutrients and fungicides use increase the productivity of Fragaria ananassa Duch Due to significant climatic fluctuations and stressful growing conditions in 2019, the research should be continued to obtain the data on various weather conditions in order to confirm the effectiveness of those products use.
