Have you checked with your Ag Ext. Service to
determine if this fungus is seed borne?  I think Byron Bromley had a
problem with seed borne disease.  What company did that come from, Byron?

Rose Marie's note to the list mentioned that she has seen sour rot on
Caspian Pink tomato plants that she's growing out this season. As you know,
numerous fungi cause fruit rots on tomatoes. Any number of species are
causal agents: Pythium, Phytophtora, Rhizoctonia, Alternaria, etc.

Since only one company is distributing seed of Caspian Pink in this country
this season, I think it would be prudent not to speculate, jump to
conclusions, imply, etc. that Marie's problems are due to seed borne fungi.
Infected soil is most often the cause of fungal problems in tomatoes.
