That has not been my typical experience with it. However when plants have a heavy fruit load they do tend to be more susceptible to early blight.

YS has been no more susceptible to disease than any other plant in my garden the past two years. Maybe you should post some pics.

I think I have TMV. I sprayed with something that made the leaves somewhat translucent and many of them are both light and dark green. Not sure what to do now - whether to pull the plant or wait till the fruit mature and then pull the plant. I think my Eva may have it too. Thank god I planted hybrids with resistance.

Liz, the chances of your plants having TMV are close to zero. TMV used to be a problem for home growers but since tobacco grown in the US has been TMV tolerant for the last 20 years there no longer is that problem.

Yes, there have been a few small outbreaks, but the major way that TMV is transmitted these days is in large commercial greenhouses where it's transmitted manually.

Hybrids have TMV resistance bred in b'c it's easy to do, and for commercial growing via the manual transission I just mentioned.

If the symptoms on your plant look like TMV as you can diagnosis from one of the better disease sites, you might consider CMV , Cucumber Mosaic Virus, which is much more common.

BTW, what did you spray that chaged the leaves so much and was it the spray that altered them such that you think they then had TMV symptoms?

I would still consider TMV. Assuming that it is only going to come from tobacco is an incorrect assumption. The virus ToMV has a wide range of hosts and TMV even wider. It can be transmitted by any kind of leaf chewing or sucking insect.

I would too K except in her other thread she described what it was she sprayed and said that the leaves were a different color after that, which does not TMV make.

She attributed her possible TMV coming from folks on the balcony above her who were smoking, which does not TMV make either, unless they were smoking Turkish tobacco and the butts landed near her plant.

It's all in that other thread Liz did.

Sounds like you sprayed chlorothalonil maybe and the white coating on the foliage is making it appear "translucent"? If so, next time you should confirm what is affecting your plants and read the labels before applying pesticides that may have no effect on what you think may be the problem. If it is a virus, daconil will do nothing to help it.

I've also had an aphid problem this year which I believe to have caused CMV in one of my plants. I quickly pulled and burned it so the virus would not be spread as easily. Insects, however, do not transmit fungal infections like blights if that is what you do have. Maybe if you can post a few pics.

I sprayed with oil, water and dish soap. It made the leaves translucent so that I could see the discoloration that was already there. I'll try to get some pics later- how do I do that here btw?

I don't know anything about tobacco mosaic virus, so I can't comment on that. Never seen it to best of my knowledge.

Can't comment on how Daconil might cause a pattern of discoloring that looks like a disease. Don't use the stuff on tomatoes.

But with regard to Yellow Submarine, I grew six vines of that variety last summer, spread out over three different gardens. One vine was in a container, one in a raised bed, two in poor, unmulched native soil and two in a heavily mulched and amended native soil garden.

I don't remember noticing any disease on any of the six plants. Maybe a couple of spots that may have been Septoria, but nothing really alarming or developed. And I did lose several plants (yanked them or outright succumbed) to Septoria and Early Blight.

So, no I don't think Yellow Submarine is unusually susceptible to the diseases I get in my gardens. In fact, I crossed Yellow Submarine with one variety that was noticeably diseased last year and the F1 plants from that cross growing this year in the same garden are noticeably less infected than some nearby plants. Septoria and Early Blight again are my usual problems.

Is it related to or an improvement on Yellow Pear? Yellow Pear isn't very tolerant of EB, I think it is especially susceptible.

Now that the leaves are off and the sun came out I took a look at the stem and there are dark spots all over it. I don't think it's late blight because the fruit are not affected at all - I have the same spots on my Eva and starting on my Enchantment. Perhaps it's some kind of bacteria, mildew or fungus. Ugh. I'm not pulling them because they are all setting lots of fruits which are fine. As I said I started Serenade this week. Perhaps I should get Daconil - does it make a difference what I spray? How do I post pics here>?

Korney - yes it's supposed to be an improved version of yellow pear. I swear I wish I didn't have this plant. I want my peacevine.

Korney, Bill Malin introduced Yellow Submarine to the States from Ireland. More info at Tatiana's site. I've grown it and it is a good one. Doesn't get as overgrown or as mealy as the traditional yellow pear. Pretty much an ordinary PL plant for most. shrug.

Yes, it makes a big difference what you spray.

If the foliage diseases are fungal, such as Early Blight ( A.solani) or Septoria Leaf Spot, then Daconil would be a good choice. But if the foliage diseases are Bacterial Speck or Bacterial Spot then Daconil will not work.

If the disease problem is a systemic disease such as Verticillium, for instance, that's a soil dwelling disease that infects thru the roots, then no spray is appropriate.

I think you said in another thread that you had the link to TAMU as a help in diagnosing problems, so you might want to check that out again and try to make a match with what you're seeing.

Yellow sub is not an improvement on yellow pear. Its not related as far as anyone knows.

Bill sent me seeds for it in 2007, that year I grew about 30 of his seed varieties he sent me but not Yellow Submarine, fearing it would be too similar to Yellow Pear.

Ironicly, that same year I grew Wonderlight/Plum Lemon from someone in OH and there must have been a seed mix-up or crossed seed & got these:

Yellow Pear was one of the first heirlooms I ever grew (outside of my family's saved varieties) and haven't grown it since!
