Best weed control
Sprayed thistles on Monday, and they were all brown and dying on Tuesday; best weed control I've used.

I didn't follow the instructions but my way worked a bit
I didn't use enough water so I can't give this an honest review. I used it on some weeds that YES it burned those suckers to a brown death. BUT, the weeds in a crack in my driveway it didn't even make them brown. The weed that I used next to the driveway and I go a little on the grass around the weed and so now I have a brown spot but I'm okay with that.

Great product!
Best product I have ever used for killing weeds and the grass that grows into the river rocks around my gardenias. I spray it on in the morning and by the evening, the weeds and grass are dead.

Can’t get better without a pesticide license
I’ve used several different types of concentrated herbicides over the years and without a license, this is about the strongest and fastest acting one I’ve come across I purchased a 6 pack in June 2024 and now that it’s Spring 2026, I have one bottle left so it’s time to recharge. I use it in a one gallon sprayer and mix 6 ounces of product to one gallon water. Kills just about everything except nut grass at that ratio. To kill nut grass, I bump it up to 8 oz per gallon. I really like how you can see results within a couple hours on a hot day and in about 2-3 days, the target weed is dead dead. I used to use the rodeo brand but ever since they changed the formula, it sucks. You might see results in about a week and it might kill the plant in 2 weeks. For cost and effectiveness, spectracide is the way to go.
