A rot may occur anywhere on any plant, but this is the first I've ever
heard of a "bottom end rot." Since the blossom end is the bottom end of a
tomato, that term usually suffices to describe any bottom rot. I'm not in
favor of complicating disease names by location if it hasn't been so
described in the past. Next thing you know, we'll have "mid-section rot" or
"top end rot" and no doubt Ortho will come up with two different sprays to
prevent same. Margaret L
