Effective, but takes time.
It’s very effective and kills every plant that gets a drop on it. It’s just strange how long it takes for some weeds to react. Some weeds died within 1-3 days, brown and crispy. Other weeds stayed green green green for over 2 weeks, then suddenly they were laying over turning brown and crispy. It’s super effective, you’ll only see dirt when it’s down, but it does take time.

Kill your weeds fast
If you are using any other weed killer, you are wasting your money. Mix, spray, watch the weeds die. You get to decide the strength of the solution, which makes this the best value for your money. I have killed more weeds with smaller amounts of this than any other amount of any other brand.

Knocks the weeds down impressively.
I’ve used liquid weed killers for decades with mixed results. I purchased this product in early 2026 and have used it two or three times around different parts of my yard. I honestly can say this product worked equal or better than any other products I’ve used in the past. I plan to continue buying and using this product.

Great to restart a lawn.
This did great to kill an entire section in lawn. This was the goal due to weeds and other infestation. Was able to plant seed about a month later last fall and had great results. This product is good for short term solution but is not meant to be a long term solution on area sprayed. It was already to mix and was exactly what I needed for my project. At the time it was on sale so it definitely was a great value. As with any chemical, be sure to wear proper safety attire. This is relatively harmless to humans following that guidance and directions.

It's ok
It does a okay job. It definitely takes a long time to work but it does kill the weeds eventually might need to do a couple of runs to make sure they're all dead.

Very efficient.
Really efficient. Kills anything and everything. I try not to use a lot of weed killer but it is necessary in certain areas. Just use it wisely as well as a mask and disposable gloves. They're not necessary but it's smart.
