Mortality of ethyl acetate phase active substance (EAP) on Pst urediniospores. a Status of urediniospores after incubation at 9°C in the dark for different times in each treatment under the optical microscope. AS, alive status; ES, emergence status; DS, death status. Bars = 50 μm. b Urediniospore mortality rate in the various treatment groups at each time point. Comparisons were made between different time points for the same treatment, and the values in the chart are mean ± SD. By Duncan’s new multiple range tests, different lowercase letters indicate differences with significance level 0.05
