Sprayed this product on my lawn as instructed. I didn’t water for 2 days after. 5 days later the crabgrass started looking wilted & slightly less healthy. The photos I included are less than 2 week after application. The crabgrass appears to be dying slowing but each day it gets browner & more wilted. Zero damage to my fescue lawn. So I am happy with this product. I don’t care if it takes a month to kill the crabgrass as long as it dies. And that appears to be what is happening. Be patient.

Don’t waste you money. Doesn’t work at all.
Reviewed in the United States on July 30, 2021

Update: After about two weeks it killed a bunch of my grass where i sprayed. The only thing it didn’t kill was the crab grass. I didn’t use anything else in that time so i know it was this spray, and the only places my grass died is where i sprayed this horrible product. This is the worst product I’ve ever purchased, not only did it not kill ANY weeds, but it destroyed my grass almost everywhere it was used.

This literally did nothing. Followed the directions exactly, it’s been over a week and none of the crabgrass or any other weed has even turned a little bit brown. Complete waste of money and time.

Well, it WAS dead ...

This stuff killed all of the crabgrass but I'm not sure it did anything about the roots.
So I used the product walking slowly and covered ~ 250sqft before the bottle was nearly empty. I think I should have moved a bit faster. A few days later I didn't see any changes, but a week later it was obvious, the crabgrass was dying. Fast forward a few weeks and the rest of my grass is thriving and beginning to fill in. Unfortunately the crabgrass came back. I'm not are if the roots survived or it was just seeds but its back. I'll spray again and add a pre-emergent. I know its not a glowing review, but this has been the most useful product I've tried.

Not effective with stiltgrass
Reviewed in the United States on August 14, 2020
Verified Purchase
I bought this to treat Japanese stiltgrass which has invaded about 1/3 of my lawn. The product comes out of the bottle too quickly and not cover as many square feet as expected. The last inch or two stays in the bottle and won’t mix in the hose and is wasted. A tiny percentage of the stilt grass got yellow/brown edges on the leaf within the first few days. It looked
Otherwise healthy and unharmed. Finally on days 7-8, i could see that a majority had begin to yellow and brown. I am hopeful it is working. The lawn is not harmed and neither is the clover.

Doesn't Work & Hurt My Lungs and Eyes
Reviewed in the United States on September 6, 2024

I saw this in a hardware store and bought their last bottle. I came home and ordered 2 bottles from Amazon. I applied the first bottle (store) to my lawn - directions said it can take 10 days to work. It never worked. And while I stay upwind anytime I'm spraying, later that night my eyes and lungs were on fire. If you buy this, use goggles and a chemical respirator. This stuff was harsh on me. I'm returning the 2 bottles I bought from Amazon. I never opened the package (have to open now to put return paperwork inside box).

I've had crabgrass in about 5 spots on my lawn for years and nothing I tried before would remove it. After one application of BioAdvanced the crabgrass disappeared in about 3 weeks. I must admit i was surprised how well this product works.
