## Description

Tackle grassy weeds in your yard with Roundup® for Lawns Crabgrass Destroyer2. This weed control product kills crabgrass and grassy weeds including barnyardgrass, foxtail, goosegrass, johnsongrass, panicum, millet, shattercane, and others as listed. In addition, this grassy weed killer may be applied before seeding, including the day of seeding (do not apply for 28 days after seeding of listed turfgrasses).

For best results, apply to actively growing weeds during early growth stages. Do not apply to bahiagrass, bermudagrass, buffalograss, carpetgrass, clover (desirable), creeping bentgrass, dichondra, St. Augustinegrass (including Floratam), seashore paspalum, or zoysiagrass. Do not irrigate or apply if rain expected within 24 hours of applying. Do not reapply this product within 3 weeks of first application. Take back your lawn from grassy weeds with Roundup® for Lawns Crabgrass Destroyer2.

Review: Great product, wish a concentrate was available, hand sprayer sometimes missing - The product works as advertised on mature wide leaf grasses such as crabgrass. I just wish it was available in a concentrate suitable for the small residential pressure sprayers. I have 50 year old acre of lawn with a strong base of fescue and bluegrass but it has become overrun. I've used a few bottles so far and is working very well and will probably need a few more bottles. However I am not looking forward to treating an acre of land one manual hand squirt at a time. UPDATED: Three of the last four bottles I purchased arrived without the hand sprayer as shown in the photo on the side of the bottle. This did not affect me as I dump them into a pressure sprayer now, but I would be unhappy if I didn't have my own sprayer. I still think it's a great herbicide for the intended purpose but the (sometimes) attached hand sprayer is mediocre at best for larger areas.
Review: Worked great on crabgrass - Knocked the crabgrass out! Takes about 4 or 5 days to see everything turn white - and after a couple of weeks the crabgrass is simply gone.

### ⭐⭐⭐⭐⭐ Great product, wish a concentrate was available, hand sprayer sometimes missing
*by R***S on August 13, 2025*

The product works as advertised on mature wide leaf grasses such as crabgrass. I just wish it was available in a concentrate suitable for the small residential pressure sprayers.

I've used a few bottles so far and is working very well and will probably need a few more bottles. However I am not looking forward to treating an acre of land one manual hand squirt at a time.

### ⭐⭐⭐⭐⭐ Worked great on crabgrass

Knocked the crabgrass out! Takes about 4 or 5 days to see everything turn white - and after a couple of weeks the crabgrass is simply gone.

### ⭐⭐⭐⭐ REVISED... More effective on crabgrass than I expected.
*by D***R on August 8, 2025*

I am revising my review of this product, but left the original below for comparison. I might have been a little hasty in my review by not allowing enough time to elapse for the product to work. Typically any sort of weed killer only takes 24 hours to begin showing its effects. With this in mind, after 48 hours I hadn't seen any effect from the Roundup Crabgrass destroyer. However, after three or four days I am beginning to see its effects. The areas that I sprayed are beginning to yellow and turn white. I have changed my rating from 1 star to 4 stars. Crabgrass is a problem in the midwest, and it's that time of year where if you don't get a handle on it, then it can easily take over your yard. Even as a lawn "enthusiast" who goes through all the stages of treatment throughout the year, the crabgrass has been especially bad. I was hoping that a product labeled "crabgrass destroyer" was going to be the solution, but alas, this product did absolutely ZERO in killing crabgrass. Surely Roundup isn't lying to us with their advertising. Hmmm.
