This article gives information about the effect on the shelf life and the technology of prolonging the shelf life of potato tubers grown on saline soils of Khorezm region (Inoyat-Jumaniyaz farm) on the technology of storage of biopreparation Zamin-M (based on strains of Bacillus subtilis, Bacillus megaterium and Pseudomonas stutzeri) listed. The dependence of the storage period on the temperature regime of the treatment of potato tuber with biopreparation has been shown. Research on the storage of potato tubers was carried out in the limited liability company "Khorezm Bakht Taminot" in Urgench, Khorezm region. The treatment period of potato, tubers treated with biopreparation that was carried out at a temperature of 19 0C for 10-15 days. The cooling period was reduced to 1 0C every 2 days at a temperature of 14-18 0C, and after 32 days it was transferred to the winter period. The winter temperature regime was 3 0C and the humidity was 85-95%. 

During the treatment period of potato storage technology using biopreparations, a technological scheme of a new spraying device for drug treatment was developed and a recommendation was made based on its operating parameters.
