I bought a bottle on spec, hoping it'd be something to wipe out the wild blackberries. (Something that takes at least 2~3 Roundup applications) It works! It really does a number on the blackberries, as well as other pesky weeds, and doesn't leave big brown spots in the pasture because most grasses tolerate it. It's now my 'go to' unless I need to clear out a grassy area.
Every 2 years, I manually cleared shoots from sapplings & bushes. Close to our wooded house,it was overgrown,looked terrible, nothing would zap it. Then, I discovered this great product, which works, is terrific! I highly recommend it, have used it for 2 years now.
