I use Cornerstone, it works very well. Same active ingredient as roundup but cheaper although you need to buy it in larger quantities. It's $60-70/gal for concentrate but it lasts a long time. I would suspect a typical home owner may likely never need more than a gallon. I buy it at the local co-op.
I have a commercial ornamental & turf pest control license and use it at a few places where we cut grass. It typically works within a week and usually lasts 2-3 months depending on the weather. A license isn't required for purchase, just the commercial application that I do.
My old'timer of a neighbor use to walk around his yard with a 5- gallon propane tank and a roofing torch and just burn the crap out of all the weeds! Worked really well every once in a while he'd haul a** to the hose because he caught stuff on fire....lol
Miss that guy, he was a b-17 bomber pilot in WWII, as a kid I could always be found at his house begging him to tell me stories, never realized till I got older how hard it must have been for him to talk about it R.I.P. Walter I sure do miss you.
