Basal Spray for Autumn Olive

Just ordered some triclopyr 4 to give the basal spraying a try. Next weekend I’d like to be out putting the hurt on some invasives.
I mix 30-40 ounces of this with 2 gallons of diesel. It kills the heck out of locust. Can't imagine sweetgum surviving it. Anything over about 4" diameter I girdle and spray thoroughly. Under 4" and bottom 18" of trunk get coated. Stuff dies promptly.
