Crossbow Herbicide Weed & Brush Killer 1 Gallon
Product Review (submitted on November 7, 2012):
I've used this almost exclusively on prickly ash. Roundup brush killer did not work, but Crossbow mixed at a ratio of a pint per 2 gallons of diesel fuel kills about 95% of the prickly ash. A higher success ratio would probably be gained if I sprayed when the plants were actively growing. I spray in the dead of winter (with snow on the ground) to prevent any wind drift from damaging desirable vegetation.
