That takes the cake (Disease pics on post #10)

Grody! And unfortunate.

Does that mean you have to grow the tomatoes in a different location, like you do with potatoes to prevent blight?

I have blight on everyone of our tomato plants! They all loaded with wonderful green tomatoes and now, I'm not really sure what to do. I've been taking the leaves and stems off when I see them, but before long, I will just have sticks with tomatoes.

On closer inspection, I believe almost all of mine have it too, to some degree or another. The four hybrids are holding up the best. I am going to rip out the ones that are affected the worst...the fruit is spotted/rotting, or otherwise the plant is not bearing much.

I am at the peak of my harvest right now, so I really don't want to spray anymore, since I'm getting a few tomatoes each day. I am going to cut the bottom leaves off of the ones that are least affected and burn them. As I understand it, the damaged parts will go on to release more spores, so you are still probably doing the right thing to keep them trimmed, Stubbornhill. But after a while, if the plant loses too many leaves, it won't have enough energy to fruit.

Also, I am cutting back the tops (sterilize the pruners first w/ bleach or alcohol) so that the plants won't put anymore energy into making new fruit. We're still getting lots of rain and I don't think mine will be able to make it far enough to ripen that fruit anyway. It is a pretty big disappointment and so frustrating. But I think at this point, it comes down to trying to make our odds better for next year.

After I get a decent harvest and rip the rest of them out, I'm going to solarize the soil too, while we are still having 80-90 degree days here (which I can count on into the first week or so of September).

ETA: Neko Chan, that is a good idea every year, to rotate them too a different spot. Also I won't plant potatoes in that spot either, since they share a lot of the same diseases.

It's impossible to completely get rid of the blight but spraying with certain fungicides can effectively slow the spread of the disease. I would consider spraying with Daconil every 7-10 days. Daconil is not organic, but I'm pretty sure there is no wait time before you can harvest.

Last year and the year before I had it... I sprayed every week with neem oil and after every rain in the evening. I lost a bunch of the tomatoes totally, but I was able to keep the blight under control on the plants with tomatoes on them, and the tomatoes developed just fine and ripened for me. So you can keep it under control on mildly infected plants.

That's what I wondered, if there was any wait time on it.

According to the online label, there is no waiting period when used on tomatoes:

Thank you for the info. I will try it! At this point, I don't really have anything to loose do I? The one and only tomato that has rippened so far had end rot.
