Does anyone have any idea what this is? Its only on the yelloween's. It took hold without me noticing because I've been so involved with packing and all for the move. I'm scared its going to spread to my other lillies in that bed. I don't have any bugs, just these horrible spots and yellowing. There are irisis in that bed, planted last fall and the tops of the leaves look like they've been spray painted a rusty yellow. Never saw that before.

doesn't this just make you sick
Yehudith, it reminds me of what happens when you mow after an application of pelletized lawn fertilizer, like weed and feed or something like that and it hits the lily leaves. I have seen it before and it looked similar to what you show. Either that, or the spreader hitting your leaves with the application. Just a thought.
Nope! I don't use any lawn fertilizers in the back. That's why I have tons of clover. You know, now that I think it, I sprayed for blackspot on roses in that same bed the other week. I wonder. These lilies are right near the others . I'm thinking of cutting off one of the stalks and taking it to the botanical garden and see if they can diagnose it for me. Also I have a friend who works at monsanto here. I wonder if she could take some in to see for me?
No neighbors on the border that do that? Maybe your friend might have some idea. Even removing a leaf or two might help, rather than the whole stalk. Do let me know what you find out, okay?
Yehudith, please post a pic of your iris damage on the Iris forum and see what they think.
Botrytis is what came to mind when I first looked at your pics. If you take a stalk to the botanical garden it may be a good idea to contact them first and make sure the stalk is well bagged up so it doesn't spread to plants there (if it is indeed a fungal disease).
Botrytis is really common and some lilies are quite resistant while others very susceptible.
Hail damage also causes marks like this but since you say it is just on the Yelloweens that cause is unlikely. Hail damage can open the way for botrytis though.
I wouldn't think your rose spray would do it, rather it seems it would prevent it since it is a fungicide.
Oh yeah! I was thinking of putting it in one of those foodsaver vacuum sealed bags. that way there wouldn't be any slip ups. I wouldn't want this yick on my worst enemy's plants.
Oh, heck. I don't know what it is but is nasty. Looks like ringworm
for plants :-((
I don't know what you spray your roses with but any of the common rose fungicides should not cause any problems. I have many lily bulbs interspaced with my roses for years now and spray the lilies when I spray the roses because I can not help ot and there has never been the slightest problem.
Thanks for the help. I also po sted on the Lillium group page. They said it was botrytis. I found a real cool pic on the Lily Nook and that nailed it http://www.lilynook.mb.ca/images/Design/Botrytis.JPG. Here's what they said on the Lillium page
> Hi Yehudith:

> In your photos it looks like botrytis has infected your lilies. Pick and burn all infected leaves as gently as possible in an attempt at stopping the spread of the spoors. Then treat what remains with a water [one gallon], baking soda [two or three heaping table spoons], dish soap [one table spoon] mix well then spray on mix making sure all foliage has a coating, leaf under side and top. After every rain or surface watering done by sprinkler you will have to re spray. This fall after the lilies have senesced remove and burn all leaves and stems then removed about 1/2 inch of top soil from your lily bed and redress with fresh soil. [I place any soil I remove from an infected bed in my potato patch it doesn`t seem to effect them but can effect many [most] various plant types] Do not just add top soil burying the botrytis spoors as they will just lay there waiting to be exposed and infect next years crop.

So I think I'll just dig the whole bunch up and be done with it. As I've said before, I really don't like them, I just kept them for sentimental reasons. Can't do much of anything with them right now, its pour and thundering and lightnig outside. I just ran out and cut all my open peonies and brought them in the house. I can't believe they wait til it starts storming to open.

Just a follow up.
I finally got a chance to get outside and work in the garden. I started stripping off all the affected leaves right into a plastic bag when I realized a lot of the sprouts didn't have any unaffected leaves. I just snapped them off at ground level and was done with it. All the other's are stripped down to two maybe 3 leaves. I also noticed a couple spots on my Pink Perfection (which I really like) and stripped off those leaves. I had bought at the organic store a fungicide that they highly reccomended who's main active ingredient is baking soda. I have this huge sprayer and I filled it to the brim. Everything in that bed got done. I mean soaked, dripping, drenched. Every lily and peony and rose in my yard got done. I poured all the left over over and around those Yellowweens. I know I went crazy, but my Lillium Regalle are in that bed and I'm not going to lose them! They are just covered with buds and if I have to wrap them in plastic wrap I will. Anyway, I'm going to keep this treatment up until everything has bloomed then I'll dig them up, wash off the soil, dip the plants and pot them up for the move. If I set bloom back by a year, so be it. I'm more interested in saving the plants. The Yelloweens I don't think will be coming with us.
Again, thanks everyone for your help.

Thanks so much for your help. I followed the directions above except I used a proprietery mix that I got from the local organic store. The main ingredient was baking soda. I've sprayed several times and the plants have never looked better. G-d willig I'll get a couple blooms this year Everything gets a good spray every week. Thnks again
