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. Review: Highly effective non-selective vegetation killer - Very satisfied with the spray effectiveness. It took about 5 days to see good results. The sprayed area kept looking more brown indicating that it keeps on working. I sprayed this with a garden sprayer and my helper used an electric spray wand. I mixed it as 3 Tbl spoons per gallon to ensure it was non-selective. It was very easy to mix as hi-yield includes surfactant pre-mixed. I started with water and then added the herbicide. It was fast spraying. I had also tried concentrated vinegar at first, but realized I needed something that also got to roots and nodules. The kill speed using herbicide is as expected. It has been several. I recommend wearing gloves when handling this concentrate as well as during spraying. This is quality herbicide concentrate. It has been weeks after the spray and there is no fresh growth in the sprayed areas. I still have plenty herbicide concentrate for the next season. This was a good purchase. ## 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.

Once took 2 weeks to see the plants dying but it always works! It kills the whole plant not just what we see above the ground. Works much faster in hot weather. ## 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.vn/products/7921996-hi-yield-33693-super-concentrate-killzall-weed-and-grass-killer](https://www.desertcart.vn/products/7921996-hi-yield-33693-super-concentrate-killzall-weed-and-grass-killer) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
