My tomatoes are going rotten from the bottom up. I can not find and grubs in
them. Can anyone suggest a possible cause.

Sounds like blossom end rot. You need to add lime, or some other source of
calcium. Might be a bit late to save your toms this year, but you'll know to
add lime next time you plant. If you plant anything in the cabbage family for
winter, they like a bit of lime too.
