Does anyone know what this is?

[jemerman]

This is happening to all of my stupice plants. The leaves grow with a downward curl, with odd white growths on the veins on the bottom of the leaves. Eventually the veins shrivel up and then the whole leaf dies and falls off. I just brought the plants outside today, they have been indoors under lights since germination.

Anyone have any idea what this is? Is it something that may go away after taking them outside, or should I just toss the plants?

Thank you.

Here are a few pics.

Did they have the same symptoms when they were inside or is it related to your putting them outside and if so how long did you harden them off before putting them outside and have you been having cold rainy weather as we have here in upstate NY?

How long have they been outside in their permanent locations?

Hi Carolyn,

They have had these symptoms since they were very small. Maybe even since germination, I'm not sure. This is my first time germinating seeds and my first time with stupice so I wasn't really sure what to expect so it may have been something I didn't really take note of until the leaves started dying. So yea, this is totally unrelated to going outside.

They grow with the curl to a certain point then basically get all crispy from the veins outward and fall off.

Today is the first day outside, just hardening them off now. They are still in small containers.

I don't know what that is, but it looks yucky.
I found this link
http://vegetablemdonline.ppath.corne...omWiltKey.html

maybe you can research it on there. And of course Carolyn probably has an idea which is why I am thinking she asked you some follow up Q's.

Could that be Cucumber Mosaic Virus at an early stage? (I was about to suggest TVM and then I saw Carolyn's post at that other place about TVM not being much of a problem anymore)

[jemerman]

Thanks for the link Jennifer, nothing seems to fit what I'm seeing here...

I looked at cucumber mosaic virus a few times while trying to figure out what this is, but it doesn't seem to fit either. Maybe it takes a form like this on young plants though? I don't know.

It looks like edema, a condition caused when the plant is taking up more water than it can transpire.

Steve, looking at pictures online of edema in tomatoes makes me think this is what it is. I never would have guessed it could be something like that. I always figured disease or some weird genetic thing, since it was all on one variety.

Thank you for your diagnosis. I'm guessing that if this is the cause that once I get them outside into their pots everything will correct itself.

I'm curious... are you growing any other potato leaf varieties?

[jemerman]

No, and this is my first experience with potato leaf plants. Do you think this happened because it is PL?

I have a small container garden on my deck, so only a few plants for me this year.

[Heritage]

I've had it on both PL and RL when outdoors. Maybe PL is more susceptible indoors, I don't know.

Just watch the watering in the containers when you move them outside. Don't let the pots sit in water and make sure your potting soil has good drainage.

Anyway, good luck, I hope that is what it is and it grows out of it.

The cups your tomato plants are in have holes at or near the bottom, right?

[jemerman]

Yea, they have fine drainage and I always let them dry out pretty good before re-watering. I once fertilized with a very dilute homemade seaweed fertilizer, that wouldn't do anything would it?

[carolyn137]

It looks like I'm late to the party but I agree with Steve completely that it certainly looks like leaf edema.

Look at the first left picture put up in this thread and compare with the top middle picture from the Google IMAGES below:

And there are other pictures if not at the above site, others that I looked at online.

I should have recognized it ASAP b'c there was a similar problem at another message site recently.

When looking at Google IMAGES just put your mouse pointer over a picture and the drop down will ID what it is and where the picture came from.

Carolyn,

I definitely think that this is the problem. Do you think that the plants will recover once I get them outside in pots?
