I have a pond with a cypress tree in it.
Rodeo contains glyphosate which is a non-selective herbicide. Non-selective herbicides will kill just about any vegetation that they are sprayed on. If the tree is established, then the Rodeo should have no effect on the tree roots. You should try to limit the exposure to the tree and only directly treat the vegetation you are trying to get rid of. Please contact your local cooperative extension office for alternate solutions as the tree is in the pond.
