Dear Byron,

Speaking of phytophthora root rot, we treated some Raspberry plants with
mycorrhiza at a vineyard up by the Canadian boarder about 30 days ago.  The
treated and untreated canes were suffering from phytophthora root rot.  The
new shoots that had come up in the untreated Raspberries were also suffering
from phytophthora root rot.  We noticed that the new shoots that had come up
in the treated Raspberries had no sign of phytophtora even though the
primary canes did.  They had to remove a large number of Raspberry plants
last year because they were dying from phytophtora.  This is the second time
we have had success in getting rid of phytophtora in Raspberries.  It
doesn't do anything for the existing diseased canes, but it seems to protect
the new ones.  I had the disease in my Raspberries last year and the new
canes didn't exhibit the problem last year.  This year the new canes are
again healthy and so are the primary canes.

Have you read any accounts of phytophtora getting into tomato plants?
