Open Discussion of Lily Mosaic Virus/Tulip Breaking Virus

Saint Bonifacius, MN(Zone 4a)

You're right Gardenerme, those do not look like tiger lilies. The foliage and foliage arrangement is wrong. Although tigers are alternate, as in your pic, the leaf shape and orientation is different. To me, they look like they have strong oriental blood in them, or perhaps another species.

On another matter, is it true that you can use either baking soda or baking powder with the same results?

Add a splodge of dawn/ivory whatever as a sticking agent. A few drops will do. then mix the lot up with water and get spraying.a

Santa Barbara, CA(Zone 10a)

Yeeks! I'm right on it! Should I just spray once, or should I do it more? We did have a week or so of very uncharacteristic hot muggy weather, and now it is the much more typical hot dry weather. Will the dry heat stop the botrytis? Should I spray all my lilies or only those with the brown spots? Can this spread to other plants? Thanks!

Winnipeg, MB(Zone 2b)

I suggest you do some research on the Net. If no time to do this, then have a look at

I had some asiatics bloom OK but now the leaves are striped with rust colored streaks. They are in one pot and I noticed in another pot that the largest bud on one of the stalks has a 2 inch long streak of a rust/brown on the outside of the bud. Are these indications of the virus? I don't water with anything but MG, superthrive, fish emulsion and a spritz of Messenger once a month. If they are infected, would the best course of action be just tossing the whole potful?
I'm going to be alot more selective about where I purchase from in the future. I work at a WMart and get talked into buying alot of the bulbs at a superdiscounted price but usually they are stressed and past their prime. I deserve better:LOL: I'm also tired of the misidentification of the colors as well.
Thank you for any advice:)

Dawn is the one dishwashing soap I don't use as a spreader/sticker. IMO, its grease cutting action is too strong and I am afraid it will also do a number on the plant cuticles (surfaces) that a wax based. I prefer amilder soap like Ivory or Palmolive. And I assume this is also the reason why they say not to use detergents.

Hmmm, This link says that the virus is transmitted by mechanical inoculation only. Here is a quote "Transmission

Transmitted by a vector; an insect; Myzus persicae, Aphis gossypii, A. fabae, Macrosiphum euphorbiae, Dysaphis tulipae, Aulocorthum circumflexum; Aphididae. Transmitted in a non-persistent manner. Virus does not require a helper virus for vector transmission; transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen."

That is congruent with everything I know and read. Of course, just like blood diseases in humans, touching does not transmit. However wounded, the juices could mix and spread the virus.

Fox River Valley Are, WI(Zone 5a)

If indeed the virus is not transmitted by pollen or seeds, a person could isolate a
much desired plant and still use its pollen and pollinate it for producing seeds. Potting it up and keeping it in the house for example.
Though I suspect only a small number of people breed lilies for a hobby and the more pressing concern is losing an entire garden of mature lilies.

Hi, I'm concerned I might have some virus-infected lilies; two of my Chiantis are showing weird spots on the blossoms, although the foliage looks fine.
Any chance this isn't virus?
Thanks,
Larisa

One more shot. This is on the same stem with a blossom that looks perfect.

Hard to say; the second picture is a little too blurry. The first one looks like sun scald maybe. I don't suppose you had a burning heat wave recently? With virus symptoms the demarcation of light and dark is usually sharp, with virus in one group of cells and not others. For example, scroll up to Moby's "find of the year".

West Seattle, WA(Zone 8b)

We don't really get burning heat waves here, but it has been quite warm. It got into the low 90's! In June! In Seattle! I would say sun scald is a possibility, especially since a couple roses in the same bed had burnt leaves last week. The blotches on the second blossom really are that blurry. If that rules out virus, then woo-HOO! Thanks so much!

Willamette Valley, OR(Zone 8a)

I wouldn't rule out virus yet, to be on the safe side you might want to isolate these plants. We had 100+ degrees down here and it hit many of my lilies hard as well as cooked a few other plants.

West Seattle, WA(Zone 8b)

Would you move them right away? I wasn't sure, since they're blooming. Well, actually
I almost just got rid of them without posting the photo; I planted over a hundred lilies in that general area, so I've got a lot to lose...

Willamette Valley, OR(Zone 8a)

If you planted over a hundred lilies in that area then I think I would get rid of them just in case. If you really like Chianti it is readily available usually at very reasonable prices. For your information, the symptoms of TBV are most prominent in reds, pinks and oranges and less so in lighter colors like whites and creams. I diagnosed it in a lily that hadn't even opened yet because the color of the bud looked funny. When I peeled it open it was quite obvious so I got out the shovel and out it went. With that many lilies you will want to be observant and keep an eye on them...

Winnipeg, MB(Zone 2b)

Dont think there is much question about it. Looks virused to me.

Lincoln, NE(Zone 5b)

Not sure if I've seen this addressed anywhere ~ are there any lilies that are more or less susceptible? While the improved tigridum (e.g., pink tigers) are not known to be asymptomatic carriers, I wonder if they or others may have inherited any of their ancestors immunities. ?

Saint Bonifacius, MN(Zone 4a)

A good portion of the lily species that McRae outlines in his book, Lilies, have virus susceptibility ratings. I don't know that there is such a thing a an immune lily, just those that tolerate the infection well. Some species are so susceptible that some growers grow them as "canaries" in the lily bed as an early alert of a virus's presence. If you can trace the parentage back to the species, you might get a good idea as to the susceptbility/tolerance of a cultivar.
Rick

West Seattle, WA(Zone 8b)

I'm taking them out tonight, then. It's no big loss, compared to what I could lose. I haven't seen aphids on any of them, so hopefully the others will be ok. Thanks for your help!



Editing to add that the 100 + lilies were all planted new this Spring, and are spread across this new garden:
http://www.lolo.com/July_2006/ ...Well the first few photos anyway. Just ignore the cat photos...you can't escape cat photos on the Web, can you?

Anyway, it's a work in progress--well what garden isn't--it's not really ready to show off or anything, but I thought I'd take the plunge.

Larisa, your kitties are way too cute! I love the pics. I see you are not into mowing lawns;-) Your garden is quite unusual! Post some more pictures as it comes into bloom. When I remove diseased plants I put them into the municiple trash, sending them far far away.

L. formosanum is one of those "canary" lilies used as an indicator of virus.

West Seattle, WA(Zone 8b)

Pardalinum, LOL! No mowing for me. In the rest of the yard, we pulled up all our grass, and tried to grow clover with the thought of turning it under to improve our soil, but so far the clover isn't too happy either. We have almost pure sand. Anyway, eventually, once we've got all the other beds and garden areas defined, we're going to plant the rest with a lawn substitute (to be determined).

This is my first flower garden. I grew up helping out on our small farm--it was my dad's main hobby, I guess, but also we grew most of our own food. But we never grew flowers!! Needless to say, I can't get enough of them now. Well, I mix the veggies right in, as you can see.

I'm hoping it will be really beautiful next year, when the roses and perennials are more filled in.

Edited to correct weirdness. Hrrm, and maybe I should clarify. This is the first flower garden I designed and started from scratch, not the first flowers I've ever gotten to grow. Still, I've been really excited about it!

That garden is waaaay cool!

West Seattle, WA(Zone 8b)

Thanks, Moby!
OK, the chiantis are out. It's a little sad though; they were making so many little bulblets. Those would probably be infected, too, right? I hope I got them all!

*sigh* I had the same few lilies in pots for like, 10 years, and everything was fine; then I go to start a "real" garden, and discover there are viruses. I thought bulbs were supposed to be easier than veggies...

Edited because I can't type to save my life.

Yes, bulblets would have the virus also.

Lisbon, IA(Zone 5a)

Larisa, that is a really cool garden! I kept humming "follow the yellow brick road" as I went through the pictures. Neat kitties too. But back to the garden, that had to be tons of work to lay all the stone and then put in the bricks to hold in the raised beds! You have my admiration! Very neat!

Diann

West Seattle, WA(Zone 8b)

Oh, I had like, five guys helping me do the hardscape. All I did was tap in some of the bricks, pile up the soil in the raised beds, and provide beer and snacks. :) The planting's the only part I did all by myself.

Lincoln, NE(Zone 5b)

Ah, yes... beer and snacks go a long way toward getting the job done. :)

West Seattle, WA(Zone 8b)

BTW I want to add that the guys gave me a lovely surprise...I had worked hard on the shape of the space, researched design options, graphed out the meandering path on paper, etc, but had focused entirely on the "big picture". The guys added a nice little detail in the center which I hadn't thought of, and didn't discover until they had done it. You can kinda see it in this shot; it's dead center of the spiral and the points are on the four compass directions. I'll be planting between the stones this fall; it'll show up better next year after that's filled in. I'm not an artist, and can't wax all poetic about design as a dialog or whatever, but still I felt really moved.


Ooh you can also see what crappy soil I've been working with. More compost!

Larissa, I'm just blown away by your design! You done good, kiddo! Can't wait to see how it progresses. I hope I don't lose track of the thread and your pics.

Love your kitties, too. I can't have them where we live, and I miss mine. I'd forgotten how much fun they can be.

Judith

Cute kitties, back to the virus discussion. If L formosanum is one of those canaries, I would think it would be difficult to see the spotching. Aren't those white? What other species are highly susceptible to virus and would they grow in zone 4?

West Seattle, WA(Zone 8b)

The inside of the trumpet is certainly very pale, but the outsides are reddish; maybe it would show well there?
http://davesgarden.com/pf/showimage/47725/

Edited to add:

BTW I have read that the Longiflorums in general are the most susceptible to virus, and hence so are the L-A hybrids. Some of the hybrids are brightly colored. Will they grow in your zone?

Columbia Heights, MN(Zone 4a)

I can't grow L formosanum, it's too cold here, but I have lotz of LAs. In fact, I've been concentrating on those for the past 2 years. I just love them.

Saint Bonifacius, MN(Zone 4a)

Actually Beaker, I know a few people that grow L. formosanum and L. formasanum var. pricei here in Minneapolis/ St. Paul(z4). You shouldn't have any problem either. I have formosanum now, but they haven't gotten to blooming size. However they haven't stopped growing yet this year, and I may still get some blooms.

Found it - my list of virus susceptible lily species, from McRae's book:
Lilium:
canadense*
formasanum*
japonicum
mackliniae*
Hmmm. Seems like there should be more, but I must not have made a note for them when I read the book cover to cover.
Starred ones I grow in my garden.

Rick

Willamette Valley, OR(Zone 8a)

L. longigflorum and many LA hybrids, which inherit the susceptibility from longiflorum... just off the top of my head.

Winchester, KY(Zone 6a)

I've been obsessive to the point of paranoia as the lilies have bloomed this year! 3 'Visa Versa' had kind of twisted leaves this spring and I tossed them. I don't even think that's a symptom, but like I said, paranoid, lol. Anyhow, now I'm afraid I actually have found it :(
Of course, it would be one I paid $9 for, and only have 1. So, do ya'll think this 'American West' is virused? There's just 1 bloom (again this year,grrrr) and I think I noticed the subtle bleeding of one color into the other last year too. Last year I thought it was only gross color irregularities to look for, now I'm concerned.

Neal, I offered an opinion on your AW on your Lily SHow thread. I don't think it looks virused.

Rick, how are you overwintering L formosanum? I tried planting one last fall close to my foundation and had it very well muched. It didn't show this year. I know Inanda keeps hers in a pot. What are you doing?

Winnipeg, MB(Zone 2b)

Yep, I'd love to know as well. Just like there's a chap up here in YWG who has managed to overwinter a japanaese maple in his garden for about 3 years so far. Grr.... I would love to know hissecret.
inanda who agrees, the last couple of pix are not virused.

Columbia Heights, MN(Zone 4a)

Solar heat panels?
