Ensuring comprehensive plant protection for a long period largely depends on the correct selection of a protectant, but it is equally important to use a suitable biostimulant. A stimulant with a balanced composition of phytohormones, amino acids and nutrients helps to reduce plant intoxication, ensures the friendly germination of tubers and the formation of a powerful root system. A well-developed root system provides an improved nutrition regime for the plant, which allows the formation of a larger number of stems, which, in turn, leads to an increase in the number of stolons, which means that it directly affects the quantity and quality of the crop, and, accordingly, the economic efficiency of growing potatoes.
