What Customers Are Saying
The Bayer Extreme Crabgrass Killer appears to be an effective product for controlling crabgrass and other weeds in lawns. It effectively kills crabgrass and weeds like Japanese stiltgrass, with most customers seeing results within 1-2 weeks of application. The product is easy to apply with a ready-to-spray hose attachment. While some customers saw immediate results, others noted it takes time for the crabgrass to fully die off, and reapplication may be needed for mature or heavy infestations. The product does not harm the surrounding grass and is safe to use around the home. Overall, the product seems to be a reliable and effective solution for controlling crabgrass, as long as the instructions are followed closely.

Would Not RecommendI 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
Would RecommendMixed 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
Would RecommendWorked 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...

Waste of money!
Would Not RecommendIf 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
Would RecommendPurchased 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
Would Not RecommendI'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...

Works On Stiltgrass
Would RecommendFor those with Japanese Stiltgrass BUY this product. Only easy way to get Fenoxaprop. Give it time to work.
That is excellent to hear Dan! Thank you so much for sharing your success with the product! Jessica
Crabgrass Killer
I used this on my lawn 5 days ago and it looks like its working. Im going to wait another 3 days before a 2nd application to finish the job completely
That is excellent to hear Ralph! If a 2nd application is needed you would want to wait at least 1 month before reapplying this product. Jessica
Waste of money
Would Not RecommendThis product does not kill crabgrass. It has been a few days since I had sprayed it on my lawn, but the crab grass still looks green and healthy. Very disappointed! 18 dollars down the drain. Can't upload photos-getting error message 400

Does not work on crab grass
Would Not RecommendBrought this product from Lowes after reading online reviews and sprayed this on my backyard where there is a ton of crab grass. It did not do the job. I waited a whole week after application but there was no change. Do not recommend this product..very disappointed.
