The antiviral action of interferon on the virus-infected biotechnological methods of potato and garlic was investigated. The dynamics of accumulation of latent viral infection in potato plants with successive reproduction for the imposition of cascade (every 7-10 days) cultivation was determined and the influence on its yield and seed productivity was determined. According to the results of serological analysis, treatment with 0.025% interferon solution ensures the absence of viruses X, S and B in plants, and also increases the number of tubers of the seed fraction. Reduction of visual symptoms of defeat of different categories of seed material of potato varieties Tiras is 46-56%. Mainly by reducing the occurrence of such mild viral diseases as common and folded mosaic, aucuba-mosaic, and to a lesser extent by severe viral diseases, namely, wrinkled mosaic, twisting and mosaic twisting and mosaic . This provides a yield increase of 3.3-11.0 t/ha depending on the seed category. The corresponding increase in the output of tubers of the seed fraction by successive cascade treatment with interferon in the process of reproduction allows to obtain additional seed material of potato, which can be planted up to 198 hectares of field. An increase in the elite's profitability of growing the elite by 71% through the use of interferon is associated with lower production costs and resource savings. The high antiviral effect of interferon at a concentration of 0.01 to 0.10% for cascade cultivation of winter garlic crops provides for a 22% increase in its yield. In this case, there is also a decrease in the visual symptoms of viral mosaics and other diseases, including complex ones. Thus, the use of cascade interferon treatments during vegetative propagation of vegetative plants allows to restrain the reinfection of seed material and to reduce the rate of its degeneration with consistent propagation.
