Leaf streak

| I don't have a rust problem up here in the north but I do seem to have quite a bit of Leaf streak. Does anyone else do anything for this. I have read to cut off the infected leaves as the infestation happens. Should they foliage be cleaned up in the fall? I assume the fungus survives the winter as it happens every year. |

| If you aren't a totally organic gardener, use a fungicide early in the season (Cleary is one of the best for this). I have NEVER heard anyone advocate cutting off leaves as a treatment for leaf streak. Maybe if you're on garden tour, you might want to cut off the badly affected blooms, but it doesn't treat or help curtail leaf streak. I hate to spray, but will hit the garden with an early treatment to help w/ leaf streak. |

| The fungus that causes leaf streak is pretty much everywhere. You are not going to get it out of your garden by cutting/disposing of the leaves. It needs a leaf injury site to infect the leaf. In our case we always get it because of a) late freezes and b) hail storms. Places with lots of wind are highly susceptible to it too. I pretty much just ignore it. If the leaves are too damaged and really turn brown then I will cut them off just to groom the garden. Newer foliage won't get it unless it too gets injured. You can spray for it and I may try that one year just to see if it really makes a difference w/o being a big cost or nuisance. |

I wrote this on your other message but will post here too.
If your a member of DAYLILIES FOR NORTHERN CLIMATES - Yahoo forum - there are several discussions regarding daylilies which seem to be prone for having leaf streak. Also Sue Bergeron is on the forum and gives such wonderful advice on plant diseases. Several northern hybridizers are also on the forum. Not a highly active forum but very useful for us colder zone folks. Julia |

Hi everyone,
We did get many late freezes last spring so maybe that was why the leaf streak bothered me so much this past summer. I am in the country so we do get alot of wind too. Maybe the cutting off of foliage I had read about was really just some grooming. Unlike just about everyone we had a very dry summer so many leaves just dried up as well, even though I watered a few times. It was just a bad summer all around for my daylilies. They weren't very happy and they looked terrible. Here's to next year. I might look for a fungicide in the spring. I assume you would wait until most of the foliage has emerged. Any new fans wouldn't have the treatment but it might cut down on some of the problem.
Thanks for all your help

| I live in Southern Ontario and my daylilies had very bad leaf streak this summer. I attributed it to all the rain we had. I did remove most of the daylily foliage in the fall and put it in the garbage. Usually I just compost everything myself. We're not supposed to use chemicals in the garden anymore, so I used some sulphur on the worst plants. Don't know if it did any good, though. |

Ontnative,
You will have to let us know next year whether or not you think cleaning up the foliage helped. I usually do that in the spring. I like to leave something there to hold the snow better. I usually leave the scapes too but pulled them out and counted them this fall while they were standing up nice and tall. I'd like to know if anyone thinks the fungus that causes leaf streak dies out over the winter here. If not, maybe cleaning up the foliage is a very good idea. |
