Would RecommendThis appears to be a very specific product. The list of weeds it kills is very short so know what you are planning to treat. I use this specifically for Japanese stilt grass and it works like a charm. The only thing I have found that kills this invasive weed. Once dry after spraying it is rain resistant. It seems to take about 10 days for the effects to be apparent but it absolutely works. Stiltweeds is an annual that spreads by seed every year so you must kill it before it seeds out you will se...

Kills crabgrass good
Would RecommendKilled My crab grass pretty good. Took about a week for it to really be noticeable. Only reason not a 5 star is to expensive compared to other brands.

Worked only for a small area and after 2 weeks
Would Not RecommendI sprayed it on my front lawn that is roughly about 2500 square feet. For the first week, nothing happened. On the second week, only 1/3rd of the lawn showed sign of crabgrass going yellow. I am not sure if it was because of high concentration in the beginning or what. The remainder of the front lawn and the backyard was not impacted by this. It kinda worked partially for me so can not recommend it to others. I bought another product from Walmart that costed 1/4th of its price and it worked simi...

Defective design spray nozzle
Would Not RecommendThis is the worst designed spray nozzle I have ever used. Very difficult to turn nozzle on and off because of the lock out tab. First time I tried to turn it off while using, sprayed crabgrass killer all over my face and shirt. Not good.

It worked okay. I’m not sure if it had enough time to sit on the yard before it unexpectedly rained.

Whirlpol Upright Freezer
Would RecommendHave had the freezer for two months and it works very well. Quiet and efficient. No frost and the LED light is an added feature we like especially at night.

it truly worked
Would RecommendSprayed on my front lawn first. You will start seeing results after a weeks, just be patient. I sprayed on my backyard a little overa week ago and the crabgrass are now brown.
Great Debby! I am please to hear about your success with Crabgrass Killer for Lawns! Jordan

Kills Japanese Stiltgrass. You have to know how.
Would RecommendI mixed 240 ml of the product in 1 gallon of water. Sorayed it on and in 7 days, voila! See picture of treated vs untreated. It rained 5 h after application. The green to the left is the untreated part. The earlier you do it the better it will work. Now i’ve added a surfactant to see if that works better. After 14 days the pesky weed is gone. No trace.
That is fantastic Richard! I am pleased to hear about your positive applications of Crabgrass Killer for Lawns. Jordan

Purchased to kill Japanese Stiltgrass
Let me start by saying I use Bayer weed killer for lawns with incredible success. So we I read a Rutgers article recommending Bayer crabgrass killer to control Japanese stiltflgrass I had little concern that this product would work well. My results were disappointing as the bottle clearly states it is intended to kill Japanese stiltgrass. I liberally applied five 32 oz. bottles to weaken amd kill the japanese stiltgrass throughout my lawn of tall fescue. The stiltgrass is actively growing a...
