The purpose of the work is to develop the technology of storing food potatoes using the drug NaturCover (manufacturer – Decco Italia SRL, Italy). This drug is widely used in organizing the storage of fruit and vegetable (primarily fruit and berry) products abroad and in our country, as a result of which its testing on potatoes is of both scientific and practical interest. Research on the testing of the drug NaturCover was carried out during 2020–2022 at the Field Experimental Station of the, RGAU – MTAA after K.A. Timiryazev. The main components of the NaturCover preparation are sorbic acid (E-200) and Carnauba wax, which make it possible to achieve a preservative and film-forming effect. Four early-ripening potato varieties of domestic and Dutch selection were taken as objects of research – Red Scarlett, Snegir», Riviera and Meteor. When laying out experiments in 2020 and 2021, the following schemes were used: 1. Dry control (without treatment); 2. Wet control (H2O); 3. 4% aqueous solution of NaturCover. Potatoes were laid for experimental storage in II–III decades of October for 1–1,5 weeks after harvesting. The experimental variants were processed in the dosage recommended by the manufacturer by spraying the solution from a spray gun until the tubers were completely wetted and then dried. The consumption of the working solution of the drug was 2 liters per 100 kg of products. The evaluation of the effectiveness of the drugs was carried out according to generally accepted methods for the following parameters: the amount of mass loss in the dynamics of storage; the yield of marketable products during and after the storage period; the amount and structure of losses after 8.5 months of storage. The results obtained confirm the trend towards a positive effect of NaturCover treatments on potato preservation. The drug is most effective on varieties with high shelf life, such as Red Scarlett and Meteor, which turned out to be quite resistant to the development of bacterial rot, which this drug does not suppress. The highest preservation was noted in the Meteor variety (75,15–76,36%).
