Default Does anyone recognize this disease?

This showed up one morning, about a month ago. The plant was in a pot so I rushed it to a secluded corner in the yard, far away from the tomato garden, to keep an eye on it and see if I could figure out what was wrong. Every time I checked it the streaking on the stem and spotting of the leaves involved more stems and leaves so I lost my nerve and put the whole thing in a garbage bag, tied it up and threw in the trash. I watched all of my plants closely over the last month and have never seen anything else like it. Could this be tswv? Anything else? I appreciate any help I get on this.

Bacterial Speck maybe?

Marla, I bought some plants from CA. a month ago. Mine started to show darks spots on the leave and now they 2 of them have lessions on the stems just like in your plant. I'm think of pulling six plants(all from Ca ) this morning so it doesn't spread to my other 18 plants. I hope someone can identify this.

The pictures in this publication are what made me wonder about tswv. Especially the picture of the stem. My disease started in the new growth. I can't remember about the leaves rolling in. "Bronzing" is the word I often see associated with tswv but so far I don't have a picture in my mind of what that exactly means. The color on my leaf could be bronze? Not sure about purplish bronze. I have a feeling it is one of those things that if I saw it and knew it was tswv I would be able to recognize it in the future.

Ray, I can't remember why I didn't think it was bacterial speck. I'll go look it up again.
Augiedog, sorry to hear about your plants. Hopefully whatever you have doesn't spread.

Marla, TSWV, Bacterial Speck and Bacterial Spot can have a similar appearance on the leaves and stem. I was originally thinking that it might be Bacterial Speck, but it might not since I don't see a distinct yellow halo around the spots that is associated with Speck. So it might be Bacterial Spot if it's not (hopefully) TSWV.
Septoria, which is something I've had plenty of personal experience with can look similar on the leaves at the early stages but I've never seen stem lesions associated with it.
Here's a link that might be helpful if you haven't seen it already.

Thanks Ray. That is a good article. I appreciate that they mention the only way to actually differentiate Bacterial Spot from Speck from TSWV is by laboratory testing. One reason I had thought Bacterial Speck was less likely is because we have already had a lot of hot dry weather and I don't have any overhead sprinklers. I use all drip and no standing water. I think our higher temperatures would favor Bacterial Spot and that is certainly a possibility along with tswv. I think one thing in my favor is that I have never seen those symptoms before and have not seem them since (plant was bagged a month ago). I'm keeping a close watch for any new areas. Again thanks for the link. I have it bookmarked.
