Ratings & Reviews for BioAdvanced Extreme Crabgrass Killer 32 -fl oz Hose end sprayer Concentrate Weed and Grass Killer

Zero effect crabgrass grows bigger and nicer

I had maybe 20 crabgrass and few other weeds and I used this like label said and nothing happened. Waste of money try another brand this one is terrible.

Worked well, also kills Bermuda Grass

Worked as advertised for me. There is a clear line between my neighbor's crabgrass filled yard and my fescue. Important: Read the instructions! It considers Bermuda grass a weed also. I had a patch of wild bermuda mixed with the crabgrass and it wiped it all out.

didnt do anything

I followed the instructions. Its been a week now and it didnt kill any of the crabgrass and it continues to spread.

Worked Perfectly for Japanese Stiltgrass

Mixed in backpack sprayer according to BioAdvanced site concentrate directions - 3.2oz per gallon for 500 sqft. Added 1.5 tsp of 80/20 surfactant. Sprayed the worst patches about a week ago, and it’s all dried out and dying already. Grass and other stuff completely unharmed. Bit expensive, but Fenoxaprop is only selective thing I could find that would touch Japanese Stiltgrass without killing everything else and this is about the only thing that has Fenoxaprop. Not sure how well it would have wo...

Best Crabgrass Killer I have Used

Worked really well on multiple large patches of crabgrass. One large area was completely killed off while other area saw a major reduction. Applied twice over the same area about a week between applications. Seems to have really worked pretty well. It does take about 10 to 14 days to get results. I plan on doing another application. It's only April so I plan on over seeding the area which is another reason not to use a preemptive application. Only complaint is I did not get the 5,000 sq ft cove...

the best

That’s the best liquid to use on your yard safe and kills all the weeds and crabgrass

Great for me, not crabgrass

Really worked well, after a few day crabgrass turned yellow then died.

did the job

turned out to be a good weed killer, pulled what crabgrass i could sprayed the rest. after about a week the sprayed area was free of the crabgrass.

Waste of money!

If you're like me trying to kill a yard full of Goosegrass (it claims to do so) Forget it! This had virtually NO EFFECT on it!

Killed Stiltgrass - just give it time

Purchased to kill stiltgrass in my lawn. Was nervous as after ~10 days I didn't see much change then almost overnight stiltgrass was dying rapidly and disappeared. Can see an almost perfect line where I did/did not spray. Highly recommend. Also cost ~15% of what my lawn service wanted to charge me.

Kills crabgrass, really

It has been 12 days since I applied this product on the first yard and 10 days since applying on the second. As of now I can see NO change in my abundance of crabgrass.

Terrible hose end dispenser design

I'm reviewing just after application, 7/28/20, and I have no idea what the results will be. The hose end sprayer with lock tabs was a terrible design. Hard to turn and impossible to know the application rate. After a maybe 400 sq ft I realized the bottle was empty! Must have way over applied. I usually credit myself with being able to make things work correctly but definitely could not with this product. I notice they now make what seems to be a far simpler nozzle control but I still wonde...

Does Not Work!

I applied this product exactly as described and 4 weeks later my crabgrass is green and thriving. A few outer blades turned purple but my lawn is still full of crabgrass.Does anyone make a product that works I'm tired of wasting my money.
