I have never tried it myself... but I would be surprised if a snail-killing dose of copper would be soaked up by the plants and carried along into the shrimp tank. Rinse the plants well, even soaking them in rinse water for a day or two with a couple of water changes and you'd probably be OK. I think a more interesting question is, will the snail-killing stuff work on snail eggs? They may be coated or otherwise protected in a way that hatched snails are not--ich is like that, only vulnerable to copper in the free-swimming stage. Good luck!
