Someone mentioned snails and blooms.... they don't generally damage the blooms here, but they do shred the leaves something awful (and maybe those shredded leaves are more susceptible to things like leaf streak?).
I did a little researching last night, and supposedly you are not allowed to ship plants (from any state in the US) unless you have a nursery license. EBay has an interesting page on this:

(I'm sure that I've bought any number of plants from people
without such licenses... I guess according to eBay I'm as guilty as the grower...)
I then went on to look up the nursery license application for my state. They expect you to sort yourself into a category (landscaper, retail, "producer", and so on), but nothing quite fits the category of a small home nursery. The closest category would be for a producer, who sells at least $1000 a year in plants. That doesn't quite fit my idea of a small scale home nursery. They also asking about "growing grounds". Hmm... my growing grounds are my back yard... I don't think these applications really have the small home owner/gardener in mind... and I really don't think I'd enjoy having inspectors randomly dropping by and into my yard.
In any event, I would only sell if I had registered/introduced daylilies of my own to sell... and since the seedlings aren't exactly cooperating, that time is going to be a ways off.
Re the Serenade.... we're supposed to get rain tomorrow, so I'm not sure if it is worth applying it today. I'll have to read the instructions (how many hours before rain).
