Sensitivity to the fungicides thiophanate-methyl and ziram was characterized for newly identified clades in the sooty blotch and flyspeck (SBFS) disease complex. There was greater variability among clades for sensitivity to thiophanate-methyl than for ziram. Significant differences in sensitivity among, but not within, clades are evidence that these clades differ physiologically. Differences in fungicide sensitivity among SBFS clades could have practical implications for management of SBFS.
