This is a recurring problem every year. I'm not sure, but neighbors
claim it is some sort of blight. When the humidity of summer finally
sets in, my tomato plants start turning yellow from the bottom up. No
matter how well I keep them watered and mulched. I've sprayed
fungicides, insecticides, and tried most everything. Neihbors and I are
at our wits end. Leaves are beginning to curl up like when aphids are
on them and the leaves on the very bottom of the plant have turned
yellow. If nothing is done, in a few weeks my tomatos will have stopped
being tomato plants and would have become compost.
Any help would be appreciated. I hate spending all this time on vines
that were beautiful all spring and then fall to pieces in the summer
Northern AL here and have the exact same disease problem with tomatoes.
We've tried every brand the local stores sell and every product out there to
prevent disease. This year we did not bother to buy all those products. We
do rotate the vegetable garden and crops. That doesn't help. Our pepper
plants also suffer some kind of disease where the leaves stay a healthy
green but become narrow and crinkled. It's not TMV. They live but make no
edible peppers. It can be discouraging.
I live in SW Louisiana, temps today at 11:15 am are 93F with humidity at
96%. We mulch our tomatoes (and everything else) with layers of
newspaper and then put dried grass clipping or ground leaves on top of
that. No yellowing at the bottom and no die off. Used to have the same
problem you had until we started mulching about fifteen years ago.
If this is a problem that occor after the palnt begins blooming and
setting tomatoes and the vine also shows signs of wilting, You most
likely have Fusarium Wilt. The only thing you can do about is use
resistant/ tolerant varieties. They will have a list of disease
resistence after thier names (like VFN) .
I might be wrong, but I don't think this is the problem I'm having. The
symptoms sound pretty familiar but the photo's look nothing like my
plants. They are wilting from top to bottom, leaves are curled (as if
covered in aphids), and leaves are dying from bottom up, but I've cut
into the limbs of the bottom leaves and found no discoloration in the
vascular tissue. Perhaps this is correct diagnosis and I'm just not
able to see what is being shown in the photo. I'll have to wait until
next season to find out I guess, when I purchan VFN resistant tomato
Thanks for the help.
My news server is losing messages left & right, so you may have mentioned
these things already, but here goes anyway:
1) Are you feeding the tomatoes? Using what, and how often?
2) Have you checked the soil's pH? If it was off, did you correct it? How?
3) Are any garden chemicals being used in the garden, or anywhere else on
the property? If yes, by whom? Just you, or another person?
4) Is the plant in the ground, or in a pot?
5) How is it watered? How much? How often? What's the water source?
Municipal? Well water? Is there a water softener involved?
I had a problem this year with some plants that I was very late
transplanting. Since they were very tall I decided to bury them extra
deep. For whatever reason they are doing very poorly with many turning

I have had the problem also but now I buy my plants from a local
Greenhouse not a big box store. I plant First Lady II, Champion,
Delicious and Celebrity which are all resistant. I mulch with landscape
material and use 5 ft cages. When the plants start setting fruit I
remove the bottom limbs, about 4 or 5. I spray about every 10 days with
a commercial fungicide and aspirin water. I spray of a evening after the
sun is off of the plants, 3/4 of a aspirin to 1 gal. of water and mix
right with the fungicide. Never water the plant just the root system.
