i had a terrible bloom of crabgrass at the beginning of the growing season. I read reviews on best treatment and this product kept popping up. well, it did not disappoint. very pleased with the results, just beware, as it can be harsh on other greens

This product is EXCELLENT for quickly killing crab grass.It smoked mine in about 3 days.I have used Tenacity in the past and wasn't very impressed.You will not be disappointed with this product.Highly recommend.

The main reason I bought this is for a severe Dallisgrass infestation all over my lawn. I get my lawn professionally treated and it didn’t stop the Dallisgrass from emerging. I did a lot of research and this seemed to be the best product. I put some sulficant oil with it. Just an ounce per gallon AND I dyed it blue so I could see the progress. It took about a week to start showing. At first the dallisgrass turned purple at the tips. Then a week later it was dried out and looked like dead weed. Unfortunately Dallisgrass is very sneaky and hides between the blades of real grass. So 5 days ago I took three passes and looked as closely as possible for every bit of it. It maybe slightly turning purple but not much yet plus these were harder spots to see. So I’m hoping for the best. It doesn’t get 5 stars because it doesn’t seem to work as well on standard weeds and crabgrass. I’ve tried in on wild violets for the first time 5 days ago and unfortunately they’re still standing tall so we’ll see. Although I think it knocked out my creeping Charlie which is huge, it’s not on the label and I also sprayed some ortho that day so so can’t be completely sure but Charlie gone bye bye. So far I can definitely recommend this for dallisgrass and so just sprayed some more after the three week waiting period on other weeds so I can’t be for sure yet. I will have to update. Just know that there are very little treatments that work on Dallisgrass so to find something is immeasurable.

Kills crabgrass and other types of broadleaf in my lawn. Just follow the instructions carefully bcoz it may kill your lawn if you applied too much. Never apply in hot weather and does not need surfactant(might kill the grass).

I like Triad QC Select because it controls a broad spectrum of weeds in my Bermuda lawn. I had an outbreak of crabgrass and spurge. After the first application, within a few days the crabgrass turned purple and as of two weeks later is completely gone. As for the spurge I had to apply a second application and three days later I can see that it is finally under control and dying. Remember to use surfactant on spurge and crabgrass. Easy to mix and use in a pump lawn sprayer.

Needed something to krill crabgrass and this does the trick. Careful on the mix though because it’s very easy to burn your lawn.

I purchased a crabgrass killer but it didn’t kill it.

I have used this item for at least 4 yrs and brought it from a farm service, but it burned down over a year ago, so i went to amazon and brought it and i think it was to old because it does work i still have a lot of dandelions and i used the same mixsure as allways but the stuff does not work because i think again its to old. I paid $50.00 from amazon and at the farm service its $70.00 but its not that old, wish i could get my money back or a newer bottle that works
