John, I think the fungicide in the Bayer 3 in 1 you mentioned is tebuconazole? I haven't looked at how the amount of active ingredient compares but there have been some studies on this and other fungicides for daylily rust that may be of interest. Tebuconazole seems to have worked well in this first one (the thesis also discusses the comparative costs of fungicide products towards the end):

You mentioned it as a drench, so this study might also be of interest:

As for UltraDawn dishwashing liquid, it was studied in this research:
