Hi, I have only a few daylilies, but got some new ones from Michele (tink) last summer. They are doing fine but last fall some were certainly showing some signs of rust. I generally just kept the infected leaves trimmed off, and did not treat them. But I fear it's time to start a preventive program. I know I will be constantly battling this, what with our humid climate here, and every fungal spore known to man floating around.

Please may I have your best methods? What to use, how to apply, and how often?

Thanks
Elaine

I've gone through the same thing and can't afford a gallon of the expensive treatment so here is what I've found also living in Florida:

I try not to water so late in the day that plants can't dry off.
The organic 3 in 1 sprays can work. I hold plants so under leaves can be sprayed too.

Right now I'm trying that "Green Magic" process and that is promising in controlling rust. You can get a gallon off Ebay for $20.
(Simple Green is not the same, it has to be "Green Magic") Use 4 oz per gallon for 1st spray and 2 oz per gallon each week after.
Rusty plants are cut back prior to 1st spray for effectiveness. I also use Green Magic in a spray bottle to hand spray under leaves of rusty ones.

Also (although I'm not a fan of the Bayer Company) the Bayer systemic fungus spray does work and I think that is about $16.95 per quart.

I have all my rusty plants in a "rusty row" single file for easier treatment. I try to buy only plants with a good rust rating although I have some well-known that were traded to me that have a rusty line, so I may not be using those in my crosses.

Nitrogen flames rust so using high N fertilizer may not be a good idea. Fertilizer with a high last number are better at retarding rust. I also use soil mineralization to make plants stronger. "Ocean Solutions" is good to use, but I don't like the high shipping charge; may break down in the near future and order some more since I've not found anything that really replaces it.

I've been told to soak new plants in Green Magic solution for 2 minutes upon receipt. Haven't tried that yet.
Rust here came INSIDE plants from a well known NC seller (Not Blue Ridge).
Plants I got from Tink were clean, but rust spores abound everywhere.
Wynn Daylilies uses some kind of $500 a gallon spray and plants I got from there have stayed clean. It also depends on how rust resistant plants are. I have plants here that have totally resisted rust thus far.

Thanks SO much Pat! Thank You! Lots of good advice there. I do always water in the mornings, but nothing you can do about rain in the afternoon . . . the new starts are not in their permanent home yet, so I will space them for good air circulation, and treat them when I move them as well.

You're so right, some have it and some have none at all. Very surprising that they can breed in a resistance like that.

I'm not a fan of Bayer products either, but I do buy the 3-in-1 for my orchids, which are very susceptible to scale. A bottle has lasted me 3 years, so I sure don't use much. Probably I should use it on the daylilies before it expires.

I have never heard of the "Green Magic" treatment, any scientific studies to back up the claims the guy makes for it. Sounds like a snake oil salesman with a cure all solution. Any major daylily growers that actually recommends the product he claims they use? Why are they using 500 dollar a gal. products rotated with other expensive chemicals if the "Green Magic" stuff actually works?
I will be interested in knowing how it works in your garden. The frustrating thing is that two years ago I had a bad rust breakout on my daylilies so I sprayed and sprayed. If I had used sugar water at the start of 2014 I would have sworn sugar water killed rust, because I had no rust at all till very late in the fall on just a couple of plants. But nearly everyone in the area experienced the same thing! The weather has been so warm so far this year, I fear a really bad year for rust!

So a really cold winter last year reduced your rust problems, you think Larry? That's awesome, but as you say not dependable and well, Sighing! down here we're never going to get enough cold weather to knock down the fungus, I think.

I'm striking out on the search for "Green Magic" anyway. So far I'm getting an organic beauty soap from the Philippines, a hydroponic plant food ($1600 for 2 gal. !! ) and other than that nothing you'd use on plants.

@Xenacrockett May I ask what the name of the organic 3 in 1 stuff is that you mention above?

There's an article on daylily rust controls from the Daylily Journal available as a pdf here: http://www.daylilies.org/RustReportFromPatHenleyFall08DJ.pdf

For those thinking of using a detergent, a study on treatments for daylily rust included dish soap, the kind you get in your local supermarket, in their tests. You can read that study here (edited to add - skip to the pages numbered 51-52 and on if you don't want to read it all):

Great articles, Sue. Thanks! I use a soapy water spray solution on my veggies and citrus trees all the time. I'll try it on the daylilies, too.

Guess that's really what the Green Magic treatment is. It says it's a 'degreaser' so must be a detergent.

Just want to clarify that the folks using the $500 fungicide are NOT using Green Magic so far as I know.

All I can tell you is my own experience with it. I thought I'd try it and if it didn't work on daylilies I could use it to clean around the house so money wouldn't be wasted.

It is still to soon to tell if it will totally get rid of rust here although I've heard of a major producer having good luck with it. You'd have to talk to the product maker for names if available.

What it does here is dry the rust up. When I rub Kleenex on a leaf and get yellow rust spores, I spray with Green Magic and then check in a few days and the rust no longer rubs off. The plant tissue where the rust was does die and turn brown.. I just pull those leaves off. This stuff also seems to sort out leaf streak before it shows since after a spraying those streaked leaves will show when they didn't prior.

Some growers on Facebook daylily sites have used it and report good luck and have pictures to show. I'm still evaluating it. Thus far it seems to work as well as any other product that I could afford.

Elaine, "Safer" makes a 3 in 1 spray and I think a company called something like "Organicide" does too.

Remember too that rust thrives at certain temperature and humidity combinations.

When temps here get into the upper 80's rust dies back in the late Spring/early Summer.
Rust is not so bad in the Fall either since the humidity tends to be lower then.

So if you have rust bad in the Spring, it may die back in Summer heat.
I'm continuing spraying now to keep from a huge Spring outbreak that might mess up pod production.

We can only hope there might be a reprieve from the summer heat, right? The rest of the year it's probably ideal conditions for rust to spread.

At least I've been doing one thing right, getting rid of the affected leaves so hopefully a few million less spores flying around.

I wish they had done a more extended study using Dawn detergent, it seems to work in the short term but still, it could seriously damage the plants in the long term according to the report. I wonder the same thing about the Green Magic? I think maybe the same could be said of some of the expensive chemicals also though, don't know how long they have been tried on daylilies so I assume they base how safe they are on how they reacted on other plants they have been used on for longer periods of time.
The first year I noticed any rust I was very zealous with removing the leaves, (the only treatment I knew) it seems to me to actually stunt the growth of the plants, but then again it could have actually been the rust itself that did the stunting, or just a bad daylily year I suppose.
I did use Dawn detergent early in the year two years ago and it seemed to be working(reducing the amount of visible rust) , but I did not have much faith in it and switched to different fungicides, not sure they worked any better.

Rust seems to wear plants out.
Makes them look ugly too.
