 That's what I thought too, but I can't seem to find any references 
 discussing allelopathy and plain old potatoes...  There are a ton of
 studies out testing the allelopathic qualities of sweet potatoes, 
 though...>>

I hope I was clear enough when I sent the last post-that I was just making a 
guess.
I do not know that much about Tomatoes and Potatoes, I am not much of a 
Gardner and they are a little bit on the exotic side for me, being that I 
have not grown a Tomato or Potato in 20 years. ( My parents always had a few 
pathetic plants every year when I was a youngster)

I will defer to Marges experience, when she says she has not seen any 
difference in density and types of weeds around her plants.

If I might be permitted to wander into unknown territory again and make a few 
more hypothetical observations.

Since both plants (Tomatoes and Potatoes) are perennials it might be that the 
toxic compounds need to build up in the soil before effecting other plants.
( assuming there are such compounds)

Toxicity to a chemical is depended on a number of factors with two of those 
including duration of exposure and concentration of toxins.
