Is there anything easy to obtain to treat leaf streak? It seems like all the cv's have it and this is the worst I have seen it.

I have been pulling off the infected leaves, placing them in a plastic bag, then to
the garbage just because it is so unsightly. Some years I leave them alone. It
disappears when the temps warm things up, or it has in years before.

Any fungicide that is used for rust is said to be good for leaf streak as well, so I've read. If you are looking for something you can get at Lowe's or some place like that try Immunox by Spectracide.

Hi Shirlee - I've never had any disappear on it's own but it wasn't to bad last year. Michelle, I do have some Bonide Fungonil w/ Chlorothalonil 29.6% . I didn't use it as I wasn't sure what active ingredient in a product I need to use! Do you think it would be okay?

Mine are worse this year also, so may have to go the chemical route too.
I'll look for Immunox next time I'm out just in case it worsens. Good info. Thanks
Michele.

Chlorothalonil is listed as one of the fungicides to use. I use Daconil which has the same ingredient.

It may be leaf damage due to cold/warm/cold, not leaf streak. If it gets better when the weather warms up, it may not be leaf streak. Could you post a picture?
Be careful with fungicides - the cure might be worse than the disease. My wife, who has written about rust and fungicides in the Daylily Journal, discourages unnecessary uses of fungicides. Some of them are pretty hazardous.

Hmmm, looks like the photos for leaf streak on the AHS website. Will take a photo
tomorrow and post it. We certainly have had that type of weather lately. Perhaps Dormantsrule and I can compare photos.

Shirlee - Here's the AHS photo and my experience is will start in the middle and work it's may up to the tips.

Even though foliage is up 12-14" , can I trim back to 6" before spraying. I have around 200 in this bed and this is pretty nasty looking.

Yes, that is what mine looks like. Also have spring sickness on some, and AHS also
shows leaf streak with some spotted areas. I checked these with a tissue to make
sure there were no pustules, and there isn't any.

Also that is exactly what mine looked like in years before, which did go away
with warmer temps. So, I don't know for sure what it really was, but I was glad
it was gone. Hope it does the same this year as well.

Yes you can trim the foliage back. In a few weeks you'll never know they were cut.

The AHS picture looks good but I bet the initial injury came from cold. A lot of my daylilies have that on the initial leaves but the new foliage which was not exposed to cold looks good. I just take the bad leaves off the plant to make it look good.

Photo of what I am calling leaf streak in my garden

Thumb of 2012-04-20/mistyfog/201999

This is only on the oldest leaves. The newer leaves are not affected by this.
I think this looks very much like the AHS photo of leaf streak.

I started to see some of that Shirlee, just this morning. Not what I would call leaf streak though. And we have been bone dry. Where I saw it I had been overhead watering the last week.

I think of leaf streak as coming in Aug/Sept. Blotchy smaller patches first.

This surely doesn't look good though. I quickly turned mine over just to check for you know what. Whistling
Nope. Not that. Never had that, but I still always check. Angel

This occurred after we had three nights of below freezing weather, and then quite a
bit of rain.

Before this they all looked lush, green, and healthy. But, as I said before, I see
this every year, and in years before, they looked healthy again after the warmer
temps began. I hope they repeat that cycle.

Yeah, I check mine too on the undersides. I see nothing of concern.

Could be leaf streak or cold damage. I see a lot of this which I blame on the freeze thaw cycle.

Dick, it certainly seems to fit in with the recent weather conditions.

I had Northwind Dancer's foilage do some wierd things. Our early warm weather sent it into a growing frenzy. Foilage looked spectacular. Then the cold came again and I was out looking at the daylilies, and Northwind Dancer's foilage on one side of the clump, looked like it had all been mashed down to the point that it almost looked like something ate the foilage right to the ground. I don't know if it was an animal or it was the cold weather. We do get a few animals, mainly skunks, possums and squirrels with a very rare ocassional rabbit. Anyway, it is starting to look like it is recovering from whatever caused the problem.
