ttx, I moved your post to the Blight thread. Read through and you may find treatment options.

ttx599 7/17/2013, 6:48 pm

I guess that means it is blight?

I am not sure what you mean..... Have you tried to determine if its blight or septoria? Do you see any brown lesions on the stalk or stems of the plant? Did you check the blight tracker? I cannot make your photo larger to get a better look.

ttx599, Looks more like bacterial speck or spot. Look for photos of those to compare.

ttx599 7/17/2013, 8:15 pm

I don't know for sure it is blight... trying to determine.... all the bottom stems / leaves look like these. There are tomatoes that are still green and the main stem doesn't show any problems. I have been trying to research what it is but I can't find a clear analysis.

ttx599, your tomato leaves look like mine did. With help from the forum, I determined that it was bacterial Septoria Leaf Spot. Here is the link to my thread.

I used diluted hydrogen peroxide on mine. 1 1/2 tsp per cup water and sprayed on. They are hanging on, so we will see how they do. Good Luck.

Since blight spores can blow around for miles it's a wonder any of us can grow tomatoes here in the sloppy-muggy state of Ohio along with so many other muggy places. Think I'll be extra appreciative for every fruit I get.

My tomato plants have late blight. Evil or Very Mad

I found some on the aubergine as well. Evil or Very Mad

I will be spraying what is left of the foliage with copper.

Thanks for the info and link camp!

Last year was the first time we ever had late blight Sad

it spread fast and killed our lush full of tomato later harvesting tomatoes.....we were so devastated Sad

we would of had a ton of tomatoes last year......we looked at our back neighbors, side neighbors and down the street neighbors and they all had the blight as well.....

we are thinking about trying the new *super-resistant 'Iron Lady'* from the article ...we were not planning on buying any more tomato seeds for this years, because we really like the ones we planted last year.....the plants were great....its the blight that was the problem.....so again thanks for posting this....it will be worth buying more seeds to see if we can have more tomatoes this year Very Happy

hope this one taste good LOL

happy gardening

Camp - I followed this link and then it led me to another link that I thought was excellent. Here is the link
http://awaytogarden.com/wp-content/uploads/2010/02/lbfaq-4.pdf

My tomatoes die from one disease or another every year. Bacterial leaf spot, bacterial leaf speck, early blight, late blight. The above link mentions using a copper spray as a preventative fungicide for late blight. Does anyone use a fungicide as a preventative measure and if so what do you use???

**camprn** 2/2/2014, 8:19 pm

I have used the Bonide copper spray and it helped with blight prevention. I bought the powder and used a garden sprayer.

yolos 2/2/2014, 10:06 pm

The following article has some very good charts at the bottom of the article that list the different varieties of tomatoes and the disease resistance. Also tables for blossom end rot and cracking varieties.

Also, just above the charts are a list of heat tolerant varieties.

This is an old article so some of the links are broken. Here are updated links:

UMass late blight fact sheet

Cornell late blight fact sheet

Did it rain a lot in your area? It appears to be associated with cool and soggy weather. Like 2006, 2009 and 2011.

Sounds like an "above-average-monthly-rain-total-disease".

What a neat map to watch.

yolos 8/7/2014, 10:01 am

ACK - there is a red dot right over the top of my house. I zoomed in on one of the red dots (meaning infection possible) and it is within a mile of my house. Oh no. Of course the early blight is already taking a toll on my tomatoes so getting late blight will just finish them off. I give up!

**camprn** 8/7/2014, 11:46 am

I saw a few early blight lesions a few days ago on two of my plants.
