- W3209187499 abstract "Objective. Monitoring observations over the phytovirological condition of potato planting in different regions of Ukraine, taking into account potato degeneration zones. Methods. Laboratory (virological, immunological, electronic microscopy), field, statistical. Results. The map and diagrams show the results of monitoring studies conducted in 2016–2020, during which 435 varieties of potatoes of Ukrainian and foreign selection were tested. In the zone of the lowest degeneration or the zone with a relatively low degree of infectious load, 100 % spread of pathogenic complexes involving potato virus Y in the Region of Zakarpattia, potato viruses M and Y in the Region of Chernivtsi, ranging from 89 % to 100 %. In the zone of strong degeneration of the culture or the zone with a high degree of infectious load, spread of pathogens of potato viral diseases is from 94 % to 100 %, and the vast majority of viruses belongs to pathogens of severe viral diseases. In the zones of mild and moderate degeneration, which belong to the zones with relatively low degree and with moderate degree of infectious load according to another diagram, potato virus M in monoinfection from 17 % to 50 %, in the pathogenic complex with potato virus S from 8 % to 36 %, with potato virus Y from 6 % to 32 % was detected. In the Region of Kyiv, the spread of potato virus Y+S complex reaches 65 %. In all areas, there is an extremely high level of infection of the culture with potato virus M, which is the cause of severe viral diseases of potatoes. Conclusion. The results of phytovirological monitoring show that the boundaries between potato degeneration zones are smoothed down. Climatic changes, active resettlement of virus vectors, intensification of trade relations with the constant import of foreign potato seed material result in the significant spread of pathogens of potato viral diseases." @default.
