Designed for both residential and commercial turf, it offers up to 90 days of effective weed management across 1000 square feet per 7.5 oz bottle. Its flexible application window and rapid action make it a top choice for maintaining pristine, healthy turfgrass without harming desirable grasses. ## Description Quinclorac 1.5L Select™ is a selective, post-emergent herbicide that can be applied to many types of turf, both residential and non-residential, to control a variety of weeds. Quinclorac 1.5L Select™ can be applied from 7 days before seeding and up to 28 days after emergence on selected weeds. Quinclorac 1.5L Select™ is an auxin agonist and is classified as a quinoline carboxylic acid. It is absorbed by foliage and roots and translocated throughout the plant. The control symptoms exhibited by broadleaf weeds include leaf and stem curl or twisting, and chlorosis. Susceptible grasses demonstrate stunting, chlorosis, and gradual reddening followed by necrosis and death. Apply Quinclorac 1.5L Select™ to actively growing weeds as post-emergent broadcast or spot sprays using the turf species, rate and growth stages indicated on the label. The use of Quinclorac 1.5L Select™ before or after seeding or overseeding a turf area will not significantly interfere with the turfgrass seed germination and growth of those grass types identified as tolerant or moderately tolerant on the label. Review: Excellent! - Works as advertised. Definitely the best crab grass killer that I have used! I highly recommend it for established crab grass. Review: Kills crabgrass at 5 til , don't overuse it - This is one of the three products that Kills crabgrass and variants that few other products affect. But it's hard on the grass and the environment, wildlife will leave for 2+ months. If you properly meter it, you can have a max of two treatments a year. If you overuse it, the weeds will adapt and you'll no longer be able to use it. It works much better with the correct MSO sulfucant I'd recommend this product as a strong crabgrass herbicide that has fast 3-14 day knockdown. The only other fast knock down crabgrass herbicide is Acclaim Extra Selective, which in some ways is superior, but is more expensive and is not easy to find. If you are treating earlier in the spring consider using Tenacity instead as it acts as both a pre and post emergent, but be aware it works slowly, growth is stunned then slow death, and has some other specific application and watering requirements if you go that route. ## Features - Quinclorac 18.92% - Residential and Non-Residential Turfgrass, Golf Course, Sod Farms - Provides up to 90 days of control ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07KYVGH9V | | Active Ingredients | Herbicide, Quinclorac | | Best Sellers Rank | #41,457 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #310 in Weed Killers | | Brand | Primesource | | Brand Name | Primesource | | Coverage | 1000 square feet | | Customer Reviews | 4.3 out of 5 stars 473 Reviews | | Included Components | Herbicide | | Item Form | Liquid | | Item Weight | 7.8 ounces | | Liquid Volume | 7.5 fluid ounces | | Manufacturer | Prime Source | | Model Number | 51507PS1275 | | Part Number | 51507PS1275 | | UPC | 653341837097 | | Unit Count | 7.5 Ounce | ## Product Details - **Active Ingredients:** Herbicide, Quinclorac - **Brand:** Primesource - **Item Form:** Liquid - **Item Weight:** 7.8 ounces - **Liquid Volume:** 7.5 fluid ounces ## Images ![Quinclorac 1.5 Select Liquid Crabgrass Killer 7.5 Ounces - Image 1](https://m.media-amazon.com/images/I/71g1HgB9wUS.jpg) ## Questions & Answers **Q: Will this product eliminate tprpedo grass without damaging surronding Bermuda grass?** A: This product is safer to use on Bermuda than Tenacity. It did not kill my Bermuda. See my review for pics. **Q: Why are there two containers in one? One container has a .5 oz of liquid and the other container has 7.5 oz of liquid. Which liquid is which?** A: The product comes with a specialized container called a tip and pour. It allows the user to measure the amount of product to be dispensed from the container. To use, simply squeeze the bottle and the liquid will fill the smaller reservoir to the desired application amount. **Q: How long before you should mow** A: Per the Manufacturer's directions: DO NOT mow 2 days before or after applying Quinclorac 1.5L Select to maximize weed control and minimize potential turf injury. Clippings from the first three mowings after application should be left on the treated area. **Q: When can you spray this on your grass** A: Quinclorac is a post emergent poison- I recommend applying early spring-early summer (depending on your region and when your last frost is). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent! *by M***L on August 15, 2026* Works as advertised.

Used the proper methylated seed oil. It went on a little heavy. It may have killed some weeds, hard to tell. But the crabgrass is still there. I tried a second application with what I still had left, and unfortunately it rained the next day, so no clue if it would have worked. -Changed review to 4 stars. It took a while, but it definitely worked. This is my lawn about a month later. Most of the crabgrass is dead. ## Frequently Bought Together - Primesource Quinclorac 1.5 Select Liquid Crabgrass Killer 7.5 Ounces - Southern Ag Methylated Seed Oil (MSO) Surfactant (Quart - 32oz) - Southern Ag Surfactant for Herbicides Non-Ionic, 16oz, 1 Pint --- ## 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.gr/products/110126047-quinclorac-1-5-select-liquid-crabgrass-killer-7-5-ounces](https://www.desertcart.gr/products/110126047-quinclorac-1-5-select-liquid-crabgrass-killer-7-5-ounces) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-19*
