Hi-Yield (33692) Super Concentrate Killzall Weed & Grass Killer (32 oz)

This is my 1st re-order of this vegetation killer. Its value, even with the price increase from my first gallon, is its biggest positive and it's a gallon, not 16 or 32 ounces. I've used most other brands like Ortho and Specticide, etc and all work but their cost is becoming prohibited, especially if you choose the ones that claim to keep weeds from returning for 6 months. Hi-Yield works just as well but its effects take longer to see. While other may appear to work faster, some within a day, Hi-Yield takes several days before the dying off shows. That's not an issue for me so I'll continue to purchase.

I used Killzall with glyphosate to completely clear out an old lawn that had become heavily overrun with weeds, especially stubborn crabgrass. Overall, I’m pretty happy with the results, but it definitely takes some time to work. I used the recommended ratio of 2 1/2 ounces per gallon water- which was 5 ounces in my 2 gallon pump sprayer. I did have to fill my sprayer three times to cover the entire lawn. Strongly recommend using dye to know where you’ve sprayed. It took about 14 days for the lawn to be thoroughly dead, and I did have to respray a few particularly stubborn areas of crabgrass. Even those resprayed areas were showing significant die-off by day 14. I added a marking dye to my sprayer, which is why the grass has a blue/green appearance in the later photos—it’s not the product itself. The progression from application through day 14 really shows how gradually the product worked. For a large area, I’d recommend being patient and giving it the full two weeks rather than assuming it hasn’t worked after just a few days. Overall, it did what I needed it to do and gave me a good starting point for redoing the lawn.

This stuff is the real deal!!! I've use plenty of different weed killers from the big box store that claim to kill all the way to roots. This stuff really does the job. Weeds or grass, it's dead and doesn't just pop back up in 2 weeks. I mix it up in 1 gallon sprayer and since I don't have to do a lot of retreating the areas it last a long time. I think it's a pretty economical choice.

This works. But works way slower than the old formula roundup I’m use to. I’m doing a lawn renovation and it took two bottles and about 14 days to completely kill the lawn.

Only needed to apply one time and weeds and grass was dead within a week. Highly recommend and loads of product due to being concentrated.

Kill All - I have used this for killing grass and weeds. So I ordered this for Bamboo, just wanted to see if it would work. Let me tell you, it works on Bamboo also. I sprayed just a few of them. I will be spraying my entire backyard on tomorrow. One of my neighbors planted Bamboo and it took over their backyard and my backyard. Only spray on the leaves, it will kill the plant. Don’t let this product come in contact with any trees, it will kill a tree fast.

Work perfectly. Less $$ than Round Up, and as far as I can see, works just as efficiently. I recommend for sure.

Acted slower than expected, but it worked well.
