Abstract: Early spotting caused by a complex of fungi of the genus Alternaria is becoming a serious problem for potato growers in many regions of Russia. The defeat of the aboveground part of potato plants by alternariasis and its further premature death lead to significant crop losses. Abiotic and biotic factors that weaken potato plants contribute to the more active development of alternariasis. The article presents new experimental data showing that the treatment of vegetative potato plants with bioorganic fertilizer “ExcelGrow” at a dose of 1 l/ha helps to reduce the harmfulness of the disease and increase potato yields. At the same time, it was found that the triple use of “ExcelGrow” at a dose of 1 l/ha in a tank mixture with the fungicides “Miravis” 0.35 l/ha, “Revus Top” 0.6 l/ha, “Signum” 0.3 kg/ha, aimed at reducing the harmfulness of alternariasis, increases the effectiveness of fungicidal protection of potato plantings from diseases, which in the end result ensures a reliable increase in yield and marketability of tubers.
