I have poison ivy that is huge, some is 2 and 3" diameter vines growing up some trees. I used to be extremely allergic to it, but have now been around it enough that if I ever get it, I just get 1 or 2 blisters. Tecnu works good to remove it from you, I just use the tools on a few "clean" logs and don't worry about it. I even tap in the spaces between vines on a tree.
A friend (who's knowledge I truly respect) once told me to put some boron on the poison ivy, it will die, poison ivy can't survive where you have Boron. I think Borax has enough Boron to work, give it a try. However, if you are organic you might not be able to use anything.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
