Doesn't act as fast as Roundup, but in the long run, it's just as good and the value is better. Just takes an extra day or two to see results. Review: ⭐⭐⭐⭐⭐ Powerful on Weeds, Including Tough Crabgrass - The area that is green are areas I didnt spray! I’ve tried several weed killers over the years, and Hi-Yield Super Concentrate Killzall has become my go-to product. The concentrate is extremely cost-effective because a small amount treats a large area, and the results have been consistently reliable. One thing that impressed me most is how well it works on crabgrass, which can be difficult to eliminate. After mixing according to the directions and applying with a pump sprayer, the crabgrass started yellowing within a few days and was mostly dead within about a week. Heavier patches sometimes needed a second spot treatment, but the product still cleared them effectively. I’ve also used it along driveway cracks, fence lines, and areas with mixed grasses and weeds, and it kills vegetation down to the root, helping prevent regrowth. For best results, I recommend spraying on a dry, calm day and making sure the leaves are fully coated. Helpful tips: - Works very well on crabgrass and other grassy weeds when applied to actively growing plants. - A second application can help with thick or mature patches. - Because it’s a non-selective killer, be careful around plants you want to keep. Overall, this is an excellent value, very effective even on stubborn crabgrass, and dependable for large or small treatment areas. I highly recommend it for anyone needing a strong, economical weed and grass killer. ## Features - Weed killer controls grasses, broadleaf weeds and woody brush species.

It is translocated thru the plant and kills it. Less foliar area means less surface to absorb the herbicide. So you should expect less effectivness if the weeds are cut to the ground. Why bother cutting them, if you are going to poison? After application of glyphosate you will not see any effects for about 14 days. Works best in warm weather (active weed growth). good luck. **Q: WILL THIS PRODUCT KILL JOHNSON GRASS** A: yes it will kill Johnson grass. Mix according to label (5 tablespoons per gallon) mix well, spray foliage surface, wait 10-14 DAYS, then it will be dead. **Q: Waiting period to replant grass sod ?** A: KillzAll only has a residual of about 2 weeks on the soil so you just have to wait 2 weeks before reseeding/sodding **Q: how long before pets can go out after it is sprayed?** A: when dry so does not stick to paws.

You will enjoy it they said.. I ended up with 15 acres and 90% of it is posion oak. I bought this and a rechargeable backpack sprayer . It does take about 2+ weeks to start to see results and 3-4 weeks before completely dead but it works!! Ive killed a good 3+ acres of posion oak trees.. not bushes...tree size ! It also killed any grass around the posion oak so this stuff definitely works. I also used the recommended dosage for "stubborn weeds" ive bought 4 gallons so far and its been worth every cent! ## Frequently Bought Together - Hi-Yield (33693) Super Concentrate Killzall Weed & Grass Killer (1 gal) - Chapin 20000 Made in USA 1 -Gallon Lawn and Garden Pump Pressured Sprayer, for Spraying Plants, Garden Watering, Weeds and Pests, Polypropylene, Translucent White --- ## 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.ie/products/7921996-hi-yield-33693-super-concentrate-killzall-weed-and-grass-killer](https://www.desertcart.ie/products/7921996-hi-yield-33693-super-concentrate-killzall-weed-and-grass-killer) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-05-23*
