At 1% per US gallon, that would be 2.56 tablespoons per gallon, or 1.28 fluid ounces per US gallon for the UltraDawn treatment. That's assuming I have calculated correctly (my conversions app says there are 256 tablespoons to a US gallon). The stronger you go with a soap/detergent solution the more chance of burning the leaves, especially if you apply it in the heat of the day.
Dana, if you can see rust pustules and there are other daylilies nearby then chances are it has already got to them.
