Using CuSO4 to control root invasion in septic systems:

I have a friend in IL who operates a private arboretum.  The septic leach field from their home runs out through a heavily forested area – and has for well over 20 years.  Twice yearly, they flush the appropriate amount of CuSO4 down the toilet, and have had no noticeable problems with root invasion into their leach lines or septic tank.

we always used salte petre.  Drill a hole in the stump and put salte petre in it and put a cork in the hole.  It will kill the tree and rot the roots, but it may take several years.

Hi,

 

My parents have a fig tree whose roots spread everywhere and into their sewage outflow system. So my dad cut the fig down. But, as you can guess, it's still alive. It's sending up shoots and still interfering with the sewage system. Is there any kind of herbicide that can be applied which will safely kill the root system without poisoning the environment?  I've never had to kill anything quite like this before so I haven't been paying attention to see what the lesser evil in herbicides is.
