“…Moreover, the presence of a large number of species of aphids -PVY carriers causes the primary reinfection of healthy potato material with this virus. The most important out of 25 species of aphids that carry potato viruses are Aphis fabae, Aphis nasturtii, Aphis frangulae Aphis gossypii, Myzus persicae, Аulacorthum solani, Macrosiphum euphorbiae) [4][5][6].…”

The aim of the research was to determine the crop productivity, yield of tubers of seed fraction and infection of basic potato seeds with viral infection depending on the period of potato desiccation, application of mineral oil Sunspray, the number and species of winged aphids in the Polissia region of Ukraine. The study was conducted in the prebasic seed production nursery garden of the Institute for Potato Research, NAAS under the conditions of spatial isolation from the main sources and vectors of viral infections of potatoes, located in Nemishaieve, Borodiаnka distr., Kyiv region in the southern part of the Polissia region of Ukraine. The subject of the research is pre-basic and basic seed material of potatoes of mid ripening varieties Myroslava, Predslava, Alians. On average for 2018-2020 years of studies, the highest seed yield was obtained by potato desiccation 10 days after flowering of potatoes - 82.4-85.3 %. However, the level of total and seed yields was low. The efficiency of seed potato production increased with the haulm removal after 20 days - with the total yield depending on the variety 20.6-30.0 t/ha, the yield of seed tubers was in the range of 20.6-22.9 t/ha with the seed content in the crop structure - 71.0-76.3 %. Late haulm removal – on 30th and 40th days after potatoes flowering caused an increase in the yield of tubers of non-standard fraction, with desiccation on 30th day, the seed content in the crop decreased by 61.1-66.0 %, and with desiccation on 40th – by 54-59.8 %. Thus, during the early haulm removal, part of the crop was lost, which during haulm removal in the late stages consisted of large tubers. It has been found out, that potato plants, where the haulm removal during 2018, 2019 was carried out within 10 days after flowering, which was 4.0 % (9.0 % for the check) for the Myroslav potato variety, 3.0 % (10.0 % for the check) for the Predslava potato variety and 4.0 % (9.0 % for the check) for the Alians potato variety were the least infected with PVM. The level of PVM infection when removing the haulm on the 10th day after flowering with the application of Sunspray mineral oil at a rate of 6.0 l/ha decreased on average for the three varieties by 1.5–2.5 %. The best option to preserve the quality characteristics of seed potatoes was to desiccate the potato haulm on 20th day after flowering of potato varieties Myroslava, Predslava and Alians and the application of mineral oil Sunspray - 6.0 l / ha. The yield was 28.8-30.0 t/ha, seed fraction 20.6-22.9, seed yield - 71.0-76.3 %, viral PVM infection was 2.0 3.0 %

“…Велика шкідливість ВСЛК, YBK, МВК, які викликають важкі і середні форми вірусного ураження рослин картоплі, пояснюється тим, що вони мають властивість швидко поширюватись переносниками, наприклад, зеленою персиковою попелицею (Myzus persicae). Ці види вірусів завжди передаються вегетативно розмножуваному потомству через бульби і спричинюють важкі та середні форми вірусних уражень на рослинах [5][6].…”

Goal. To establish the effect of a multicomponent preparation of biologic origin on seed potato productivity and viral diseases infestation in condition of southwestern Forest Steppe of Ukraine. Methods. Field method — the trial plots were set in selection-seed production rotation of Bukovinian state agricultural research station of Carpathian region Institute of agriculture NAAS. Laboratory-field method — determining crop capacity and tubers structure in a yield. Visual method — plants infestation assessment. Comparative-calculated method — to determine the potato stands productivity and viral diseases infestation degree. Results. Avatar-2 Zahyst is a system-contact preparation of virulicidal, fungicidal, and antibacterial action. It is recommended for use on grain, technical, vegetable-, and fruit crops. The preparation is used for pre-sowing seed treatment, as well as for vegetating plants treatment. When determining the seed potato productivity depending on the biopreparation Avatar-2 Zahyst implementation, no significant difference in tubers yield was established; on the variety Slauta it stayed within 34.5—36.3 t/ hа, and on the variety Kimmeria 36.7—37.4 t/ hа. No any significant difference was established also in quantity and tubers mass per one bush, as well as in one tuber average mass, and tubers fractional composition in a harvest. When determining plants infestation with viral diseases, it was established, that the biopreparation Avatar 2 Zahyst application has influenced the decrease of seed potato stands infestation. The variety Slauta damage on the variant with seed poisoning and three-times spraying during vegetation made 2.5%, which is by 2—3% lower than on the control variant. The infestation of plants where only seed poisoning was implemented made 3—4%, when of those where three-times preparation application was carried out during vegetation — 2.0—4.0%, which is by 0.5—2.5 and 1.5—2.5% lower than the control variant, respectively. The same tendency was observed during the variety Kimmeria investigation. Conclusions. The use of the biological product Avatar-2 Zahyst does not give a significant difference in the yield of tubers. The introduction of the biological product Avatar 2 Zahyst influenced the reduction of the incidence of viral diseases in potato seed plantations.
