Thanks for the comprehensive disease indentification page.
Unfortunately, it
appears to be late blight. It's strange that I didn't
notice this until just a
couple of days ago. The disease has progressed
rapidly. It is especially bad on
the Gold Nugget which had been doing
so well all summer. It's nearly completely
destroyed the Quali T-23.
Almost every branch has those characteric water soaked
lesions. Much of
the foilage is infected. A half dozen other plants have mild to
moderate
symptoms. Another half a dozen have not yet shown any signs of late
blight. And now it's even gotten to the wonderful Purple Calabash. Just
when
they finally got well-established. The causes were probably the
cool, humid
weather, the fact they were planted close together, lack of
nutrients stressing
the plants, and most importantly, the mistake of
planting tomatoes in the same
location for 2 consecutive seasons.

Anyways, can cuttings be taken from non-infected branches? Can late
blight
spread to peppers? Is there a (practical) way to sterilize the
soil so tomatoes
can be grown next year?

For home gardeners, there sometimes isn't much choice but to plant in
the same place for consecutive seasons. I have a large lot by the
standards of the area I'm in, but the areas I can put in a vegetable
garden are limited. Raised beds offer some relief, as I can dig out
the soil and replace it every couple or few years, but I'd have to do
without a garden to avoid consecutive plantings.

The advice some of these garden sites give is really unhelpful, but
that's a peeve for another time.

Late blight is not much of a problem around here, so I have no
experience with it. A quick google on the subject gives some
conflicting information, too.

Good Luck!
