Abstract: The article presents the results of research to study the effect of drugs based on mineral oil on the accumulation of viral infection in the process of reproduction. Research methods. Field, measuring, weighing, statistical. Research results. On average, during the years of studies in 2018–2020, the highest seed yield was obtained by potato desiccation 10 days after potato flowering – 82.4–85.3%, but the level of total and seed yield was low. The yield of potato seed material increased with the removal of potatoes in 20 days – with a total yield depending on the variety of 28.8-30.0 t/ha, the yield of seed tubers in the range of 20.6–22.9 t/ha for the seed content in the crop structure – 71.0–76.3% was obtained. Conclusions. The yield of potatoes depended on the period of desiccation of potatoes, and significantly decreased with early removal of potatoes. Removal of potatoes 10 days after flowering ensured a yield of seed tubers in the range of 18.2–19.0 t/ha, the seed fraction yield was 82.4–85.3%, 20 days after flowering – 20.6–22.9 t/ha, the seed fraction yield was 71.0–76.3% of the total yield. The potato plants, where the removal of potatoes during 2018, 2019 was carried out in 10 days after flowering, which was for potato varieties Myroslava – 4.0% (the control variant 9.0%), Predslava – 3.0% (the control variant 10.0%), Alians – 4.0% (the control variant 9.0%)) were the least M-virus infected. The level of M-virus infection when removing potatoes on the 10th day after flowering with the application of mineral oil Sunspray at a rate of 6.0 l/ha decreased for potato varieties Myroslava –by 2.0%, Predslava – by 1.5%, Alians – by 1.0 %. It was established that no potato plants infected with Y, L viruses were detected.
