The paper presents studies of the effect of ozone-air treatment on the preservation, yield, fungal disease damage and chemical composition of shallots of the Lira variety. The effect of concentrations of 10, 50 and 100 ppm O3 and exposure times of 10, 60 and 180 min was studied. The positive effect of ozone on reducing losses from diseases during storage and during the growing season was established, an increase in the productivity and marketability of shallots was achieved, as well as an improvement in a number of chemical indicators of the product.
