Will Ranger Pro kill bull thistles?
if so, will the thistles grow back?
Ranger Pro Herbicide - 2.5 Gallons will kill thistle. Bayer Advanced Brush Killer Plus Concentrate will provide season long control of thistle. This product is both a pre and post emergent that contains a 6 moth long residual that keeps the weeds at bay.
