Potato (Solanum tuberosum L.) is one of the main food crops worldwide, including in Kazakhstan. Viral diseases are a major constraint to sustainable potato production, as they cause large losses in crop quantity and quality. To determine the current status of potato production in Kazakhstan, we studied tuber and leaf samples in large seed and commercial farms of the Republic. Samples of tuber and leaf samples randomly sampled were tested for five main viruses: potato virus Y (PVY), potato virus X (PVX), potato virus M (PVM), potato virus S (PVS), and potato leafroll virus (PLRV). A multiplex reverse transcription polymerase chain reaction (mpRT-PCR) was used to monitor viral infection. During the monitoring of tuber samples, it was found that the most common virus in almost all regions was the PVS virus at 64.5%. Moreover, most of the viruses originated in commercial farms. As a result of the analysis of leaves selected in the fields, it was found that the most common viruses in the regions were PVM at 46% and PVS at 35.3%. The work performed to monitor viral diseases in various regions of Kazakhstan will enable direct actions to maintain and improve the phytosanitary status of potatoes in Kazakhstan in the future.
