I have talked with some people up in the Vancouver B.C., area and they have
claimed to not have grown a ripe tomato in the last 10 years because of a
late blight that comes in and rots all the tomatoes before they can ripen.
This particular person is a Mycologist and he has been frustrated about that
situation for a long time.  Because that has been going on for so long, I
suspect they have not been able to find any solution for that blight
situation.  It's a highly populated area.  Is anyone on this list familiar
with this particular blight?

The area also has a lot of agriculture going on.  We visited an aquaintance
in the that area last year and he had a bannana tree and a fig tree growing
in his yard.  He said they rarely get frost there and when they do it is
generally in late December.  The blight comes in on the tomatoes mid to late
