>> Subject: A Scientific Expedition? <<


 I have used wild collected plants without problems by simply rinsing them
thoroughly, making _sure_ to remove all large aquatic larva (dragonfly lava in
particular) and then quarantining them for 30 days or so.

 If your plants really are a Valisneria sp., or as is more likely, a Sagitaria
sp. a copper based medication is definitely a bad idea.  Both genus' are very
sensitive to copper.
