Product Description

Roundup® For Lawns Crabgrass Destroyer₁ is a tough weed killer that is formulated to kill even the toughest listed grassy weeds, including crabgrass, foxtail, and goosegrass. This weed killer spray absorbs on contact and starts working immediately. It enters weeds through leaves, roots, and shoots and moves to the growing points of target weeds. The product works by stopping plant pigment production, causing treated weeds to turn white and stop growing. Affected weeds turn brown and are controlled. Roundup® For Lawns Crabgrass Destroyer₁ is for use on Northern lawns, including Kentucky Bluegrass, Fine Fescue, Perennial Ryegrass, and Tall Fescue. Apply to actively-growing weeds when daytime temperatures are between 45° and 90°F. It can even be applied before seeding of tolerant turfgrasses, including day of seeding. The easy reach extendable spray wand reduces back bending while the continuous spray reduces hand fatigue. Do not enter or allow people or pets to enter the treated area until spray has dried.

I almost never leave reviews for products but I rely heavily on them when I am buying. I am leaving this one in hopes that it will be helpful for someone else. I live in eastern PA and my lawn over the last few years has been overrun with crabgrass. It’s getting to the point where I have more crabgrass than the good kind. I bought this in hopes that I could eradicate a good portion of it prior to aerating and seeding this fall and working to make my lawn healthy and vibrant again. Let me just say, it works.I waited for the temps to drop below 90 and went out early evening to spray. Within a couple of days I saw the telltale sign of the blades whitening and got excited. It did take several more days to start to brown up and die. None of the surrounding grass (what little there is) was affected. A few days later I went out early morning and reapplied to areas that didn’t seem to respond. They are now starting to show the same results. While I will have a lot of thatching to do and will have ugly bare spots for the rest of the summer I am excited thinking that I may be able to restore the lawn to its former glory within the next couple of years. It’s not a sprint for me. I hope this review proves helpful to others.

Reviewed in the United States on July 17, 2023

I have never had a crab grass problem, my lawn is always healthy and if I see any I ick it when I mow. This year we had major renovations and my entire yard, 1/3 acre of land was fresh new soil with not a single blade of grass. It was April which is way to early to plant seed but I had no choice so I planted and got ready to fight the weeks. Grass came up ok at first then came the crabgrass. By may 1/ of my lawn was very healthy crabgrass. During that month I tried many things to kill it but none of it did anything until I found this crabgrass destroyer. It look some time but my lawn is now 95% crabgrass free. I started with spraying the ENTIRE lawn... a week later the crabgrass was still growing but it looked like it snowed my lawn was so white. That week I sprayed more targeted and it was time to fertilize ( feeding and killing weeds yay) week 3 much of the crabgrass was nearly dead so I hit it a 3rd time again in a targeted fashion. Wait 2 weeks and about 90% of the crabgrass was dead and gone and my lawn was recovering those spots.... then came the heat, crabgrass loves heat which is why it usually starts near the curb or cement. With the heat came a surge of the crabgrass trying to return but I was ready and it hard right away before it had a chance to get large enough to leave a dead spot. 1 more treatment a week later and I'm done, basic upkeep and hit the stragglers I missed along the way. Did not hurt my fresh baby grass, it's healthier than I expected for early planted seed. I am holding off overfeeding since this may inhibit that from emerging but the bluegrass is healthy enough already that it's spreading giving me some density.

This stuff works, my crabgrass turned white and then died. However, it took about 1-2 weeks for all the stuff I treated to begin changing color. I was almost ready to reapply thinking I did something wrong. The battery powered sprayer was excellent. It didn't give me any trouble, but I was really surprised at how fast the whole jug of spray disappeared, I have a tiny lawn and a 2 sessions of spot treatment left me with nothing left. I don't think I'd do it again for the price. I will hang onto the sprayer for future use after I run some water through it.

Reviewed in the United States on October 5, 2019

Had to grow a new bluegrass back lawn this summer. Wrong time of year I know. Had no choice. In 2 months crabgrass and crabgrass like weeds of all kinds. Weeds so thick you could not see the grass! The lawn was a joke. I was sure I'd have to kill it all and start a new lawn in the fall. But I used this product before cutting it all short and was amazed. Lot of crabgrass turned white and others turned yellow. But it all started to die. Took about 6 weeks and some spot killing but the results are amazing. A beautiful bluegrass lawn! Just a few lone weeds pulled by hand. This is an amazing product.

The jury is still out on this one. The sprayer came separated from the product. (but it came) Three days ago I sprayed the product on my crabgrass. This morning the tops of the crabgrass were starting to turn white. Not the instant reaction I expected but we will see what happens.

Ok, here's an update. The crabgrass appears to be dying. However, I now have a green and WHITE lawn. The crabgrass is white, and, of course, the remainder of the lawn is green. I wanted to get rid of this weed but it appears to come at a cost - a weird looking lawn for the next few weeks. Well, there is always next year. I have mixed feelings - the weed is dying but the lawn looks very strange.

Crabgrass killed !
Thank you ROUND-UP!! One application and, just like it says, the crabgrass turned white - and it was gone! Dead, dead, dead.....

addendum: so the crabgrass is dead and so is the grass around it ! this is potent stuff and almost acts like you used regular RoundUp; it killed everything around the crabgrass.
