Thumbs up!! ### ⭐⭐⭐⭐⭐ Crabgrass killer *by W***S on August 2, 2025* Great product seems to work well take a long time to take affect and then all of a sudden the crab grass dies ### ⭐⭐⭐⭐ Works on Dallisgrass! *by G***N on August 26, 2024* 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. ## Frequently Bought Together - Select Source Triad QC Select - 3-Way Herbicide with Quinclorac (Quart) | Controls Dandelion, Clover, Crabgrass, and Many Other Broadleaf and Grassy Weeds - Southern Ag Surfactant for Herbicides Non-Ionic, 16oz, 1 Pint - Liquid Harvest Lazer Blue Concentrated Spray Pattern Indicator 8 Ounces Perfect Weed Dye, Herbicide Fertilizer Marking Turf Mark and Marker --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.ke/products/172991863-select-source-triad-qc-select-3-way-herbicide-with-quinclorac](https://www.desertcart.co.ke/products/172991863-select-source-triad-qc-select-3-way-herbicide-with-quinclorac) --- *Product available on Desertcart Kenya* *Store origin: KE* *Last updated: 2026-06-24*
