Is isopropyl alcohol safe as weed killer

I have been using alcohol to kill green mold on deadwood.
at times the mist finds it’s way to weeds in the area and kills them quite nicely. would this be safe weed mitigation as a general practice?
BTW Jonas, the book was well done!
thanks, Mike

Thanks Mike - am happy you enjoyed the book!

Alcohol is good for killing the weeds, but I don’t know how much, if any, is OK for the bonsai. I’d limit the use to the deadwood or bark unless someone can point us to evidence that suggests it’s safe for trees.
