The development of low-cost and environmentally friendly methods of post-harvest processing of potatoes aimed at improving the preservation of products is an urgent problem that requires appropriate scientific and technical solutions. The purpose of the research is to study the effect of drugs Vitamar, and Ecogel on weight loss and disease incidence of tubers during long-term storage. Studies on the effect of post-harvest treatment with these preparations on the preservation of potatoes were carried out during 2021–2022 at the Field Experimental Station of the RGAU – MTAA named after K.A. Timiryazev. The object of research is two early varieties of Dutch breeding (Red Scarlett and Riviera). The scheme of the experiment provided for the following options: 1) Without treatment (dry control); 2) Water treatment (wet control); 3) Treatment with Vitamar preparation; 4) Treatment with Ecogel preparation. Potatoes were laid for experimental storage in 2–3 decades of October for 1–1.5 weeks after harvesting. The experimental variants were processed in the dosages recommended by the manufacturer of the preparations: Vitamar – 0.1% solution of the drug and Ecogel – by spraying 12.5% solution from a spray gun until the tubers were completely wetted and dried. The consumption of the working solution for both drugs was 2 liters per 100 kg of products. The prototypes were placed in propylene nets with a capacity of 5 kg, which were then placed in plastic containers. The repetition of the experience is fourfold. The samples were stored in an experimental potato storage at a temperature of 2–4 °C and a relative humidity of 90–95%. The effect of treatments with protective preparations Ecogel and Vitamar, on the preservation of potatoes was revealed. The nature of their action depends on the varietal characteristics of the culture. According to the Red Scarlett variety, which was characterized by potentially lower preservation, Ecogel treatment allowed to increase the yield of marketable products after storage by 9.27%, compared with dry, and by 6.53% – with wet control, and Vitamar – by 8.25 and 5.51%, respectively. For the Riviera variety, a decrease in losses from late blight and wet bacterial rot was observed, the defeat of which was not noted on the treated variants.
