Effect of bacterial agents and Bitoksibacilline (BTB) treatments of potato plants on the prevalence of potato virus Y (PVY), potato virus M (PVM), and potato virus S (PVS) in potato plots on the 31st day (2019) and 29th day (2020) after treatment: percentage of samples that tested positively for each virus (I) and samples that tested positive for two viruses simultaneously (II). Data represented as mean values ± standard error; values followed by the same alphabet within a column are not significantly different from each other according to Tukey’s honestly significant difference (HSD) multiple-range test at P < 0.05.
