Concentrate Glyphosate Concentrate Grass & Weed Killer Herbicide, 32-Ounce

Effective, but I have found thicker-blade grass to be quite resistant to this, needing 2-3 daily applications and about a week before seeing things die off. It can kill off larger plants with larger stalks and leaves, but these can take 3-4 applications and a couple weeks. Thin grasses respond within 36+ hours to a single application. But overall, yes, it does get the job done. Everything eventually withers away... you just need to be aware that not everything withers away at the same time or with the same speed.

Good product. Takes a few days to kick in good but it'll kill for a month, maybe a tad longer then I respray. Saves from weedeating a bunch. Much better than Spectracide and a lot cheaper than RoundUp. Very economical per gallon. I use it and a Harbor Freight sprayer and it clears really good.

Takes a few days to work but foes a great job.I dont have grass just dg and soil and rocks but the weeds still grow strong esp after the winter rain in So. Cal. This spray is easy to mix with water in my electric sprayer and always kills the weeds after a thorough application.

EDIT: "This does work and very well. Just don't be in a hurry as it takes several days for the plants to die. Not only that, but once the poison ivy is dead, it does not come back." For some odd reason, I now have poison ivy invading my yard. Given my past history with PI exposure, and I assure you, it is awful, I had to destroy this as quickly as possible. I mean seriously, pictures of it scare me. This item, which had the same chemicals as more expensive brands, sounded like a good solution. I mixed the ratio according to the instructions, did some test patches and waited. Next day, nothing changed. I double down on the ratio and try again. My attached photos show the poison ivy is still thriving four days later. I needed something that would work. This did not.

Compare-N-Save Concentrate Glyphosate (41%) wipes out weeds and grass fast, with results in a few days, but it kills everything it touches, so I had to be super careful around my lawn. Mixing 2.5 oz per gallon worked well for tough weeds.
