Still the Gold Standard in Weed Killer

Still the Gold Standard in Weed Killer
I've been using Roundup for 20 years for my parents as well as my house. It's been the most consistent reliable chemical for weed killing - I would strongly recommend getting a general pump sprayer as the ones Roundup sells just doesn't have enough pressure especially for bigger weeds. I bought a cheap pump sprayer from Home depot and use it with this refill - It lasts me about a year before I need to get another refill. I have a 7500 Sq lot in SoCal so we do get a lot of weeds and with the rain lately, it's been more heavier than normal. Roundup remains my go to for weedkiller and I would encourage you to use the same if you haven't already!
