I checked those wilted tomatoes and there's no cut worm damage. It
can't be chemical attack because I don't use chemicals and our house
is in the middle of 11 acres with nothing near us that could do that.
The tomatoes are in cages and growing in stone terraces that are not
accessible to critters. One of the wilted tomatoes is a Big boy and
the other one is Whopper. The heirlooms like Brandywine which are
right next to them, so far are fine.
I think there may be some kind of pathogen in the soil since I'm not
having, nor have had any problems in any other areas, other than the
terraces; and a lot of the extra soil in those terraces was brought in
two years ago when the terraces were built. My plan is, in the fall
when the current crops are harvested and the plant are pulled out,
to wet down those areas and put down clear plastic and leave it down
for several weeks and hope the heat will kill whatever it is in the
soil that was causing these wilting diseases.

June
