Safe herbacide for banks

What's a good herbacide to kill vegetation on the banks? Something that will kill brush but not hurt the fish if it gets into the water.
Mostly trying to get rid of small sycamores, willows, chinese tallow.
Thanks

Rodeo

For younger brush "Hardball" might work for you. I personally like Hardball and Roundup Custom or Rodeo mixed because that will get the broadleaf and grassy weeds at the same time if you want to get most all the vegataion around the banks.

Sorry, I'm not sure if the Hardball even comes in quart size containers. If it doesn't you cannot get it without a license.

we use Roundup
