Substitution for Round-Up

Question

If I was to make a homemade recipe for weed control (using vinegar mostly 90%, 2% rubbing alcohol, 2% soap, and 4% bleach) and was to spray under mature spruce or pine trees for grasses, would this have any affect on my trees? Hate to spray for grass and kill my trees. Most trees now are in the 20′ range. I used to use Round-up for all my grass control, but now it is banned in Ontario, Canada.
