Thanks for the links Becky and Michele!
I get a lot of rain so the overhead watering is nothing I can do about. I usually water my Hostas in the morning because of the slugs, it reduces my numbers by 80% and I do not have to use chemicals for that problem but occasionally use an ammonia spray which dissolves the slugs and their eggs.
Hopefully I will find a happy medium with the daylily rust, but the good thing about watering in the morning is that the ground surface and foliage will be dry by night time. That would probably be the worst time for fungus to develope. I might try the milk spray also because it is a cheap anti-fungal. I need it for the Asters and Monarda which get the White Power Fungus. Also I recommended it to a friend at work for her Hibiscus and she was ecstatic.
I was reading the digest this morning about 'Daylily Rust' and they mention different chemicals and updated their knowledge of these chemicals. I noticed one product, ' azoxystrobin (Heritage)' has promising results as a drench not a spray and only for 4 months and this stuff is expensive!
If I was in the Daylily Business I would do and purchase what ever was necessary to protect my investment but as a Back Yard gardner, I have to draw the line some where. I have to stick with the more organic stuff and home remedies because they are cheaper not because I am a organic person. I like to be! LOL.
Also in the Daylily Digest they mentioned the Dawn Dish Soap and I was thinking if the Dawn is more effective as a insecticidal soap then I will just use that and forget the Naptha. I will be watching for the exact dilution rate.
