INCIDENCE AND SPREAD OF CEREALS VIRUSES IN 2020–2021 IN UKRAINE

Cereals play a significant role in the Ukrainian economy and agriculture. Viral diseases can cause serious reduction yields. Aim. The aim of work was to identify determine spread grain viruses main cereal-growing regions Ukraine period 2020–2021 using different methods virus detection. Methods. Enzyme-linked immunosorbent assay used commercial test systems by for wheat streak mosaic (WSMV), barley stripe (BSMV), brome (BMV), dwarf (WDV), High Plainswheat (HPWMoV), yellow virus-PAV (BYDV-PAV), virus-MAV (BYDV-MAV), andcereal virus-RPV (CYDV-RPV). Transmission electron microscopy direct Reverse transcription polymerase chain reaction performed molecular methods. Results. Summarizing results obtained methods, we say about circulation WSMV, HPWMoV, BSMV, BYDV-PAV, BYDV-MAV agrocoenoses 2020–2021. Significant prevalence dominant WSMV have been shown, with degree damage symptomatic plants reaching 52 %. HPWMoV Kyiv Poltava has established, although previously detected only eastern part our country. more likely induce monoinfection (70 %). Conclusions. During testing agrocenoses most common were (52 % 19 %, respectively), also found BYDV-PAV winter oats.
