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

Let me start by saying: Rest in Peace, weeds. You had a good run, but Killzall showed up like the grim reaper with a spray nozzle. This stuff doesn’t mess around. It didn’t nuke the weeds on contact like some kind of toxic superhero—nope, it took a few days. But once it kicked in, those dandelions and crabgrass were withering like they just read a bad Yelp review about themselves. Even the cocky weeds that had been thriving for years? Gone. They never saw it coming. The mix ratio is easy: 2.5 oz per gallon of water, which I now know is just slightly more than “eyeball it and pray.” My only gripe—and the reason this didn’t get five screaming weed-death stars—is that there’s no measuring cup. Come on, Killzall, throw in a little cap measuring doohickey so I don’t feel like I’m doing back-alley chemistry in my garage. Still, the concentrate goes a long way. I treated over 6,000 square feet, and I still had enough left to make my neighbor jealous and a little nervous. So no, it won't work instantly, and it won't hold your hand with fancy measuring gadgets, but it will turn your yard into a graveyard for weeds—and honestly, that’s all I ever wanted. Would I buy it again? Absolutely. Next time I might even throw in a lab coat for dramatic effect.

I have a two gallon electric sprayer. I didn't even read the mixing instructions, I just dumped the whole 32 ounces in and then filled the rest of the two gallons with water. Added a half cup of dish soap to it. I spray it on heavy on the problem areas and then at least a small spray on the already clear areas. Even with all the rain this year it's minimized the weeds tremendously. It did take a couple of days to see it working but I'd rather have the long lasting effects this has than the quick acting and quickly disappearing effect of the other products I have tried. Warning: I got a little too close to my grass in the backyard and the rain seeped this stuff into my lawn a few inches. It will kill your grass just as well as the weeds so be warned. I have a lot of rock and gravel areas though and this stuff has been the best besides burning them with my propane torch which I have done before. Less noisey and less dangerous than burning, and honestly seems to last longer in my opinion.

Had a distinct chemical taste. Even when cooking rice with it, the chemical taste pervades the dish. Applying directly to vegetation though kills it like a charm.

I used this product to kill weeds in my gravel driveway. It worked really well and prepared the ground for fresh gravel. I gave this a 4 because I don't like using non organic products, but my contractor swears by it.

*Update* If I had been patient. It took over a week but it cruelly did kill everything I sprayed. It doesn’t work as quickly as I’m used to but give it about 8-10 days and you will see all the weeds, grass, and broadleaf plants die. Don’t buy. Product does not work, I mixed according to the directions. It is hot 90+ and sunny and it turned the weeds a weaker yellowish green after a couple of days but did not kill them. The weeds sprang back to life after the next rain. And these weeds are in a gravel driveway so it’s not the most hospitable conditions for vegetation either. Wasted my time applying this product in the hot humid Tennessee summer. Now I have to do it again but with another product.

About a new sprayer and sprayed my weeds I had around my front of my yard near the road killed all the weeds and took a bit longer than I thought it would but it done a wonderful job killing all the weeds. It's a lot cheaper than Roundup and for the money I do not think you can find anything better. I think it's very concentrated linkage I didn't have any problem with and color is like almost to clear a little bit of a yellow tint to it and not very to use but I also added dish soap to mine makes it work better

Got this stuff to clear out a few weeds on my property and it does work just take a while. For me it took about 2 weeks to see results and fully dead weeds in 3 weeks. It's not the fastest weed removal stuff but it will cover a large area with just a little bit as it is concentrated. I did a few test spots with increasing the mixture and it doesn't help. The recommended amount vs 2x the recommended amount did not change how fast the weeds die. On the plus side it doesn't smell when mixed with water so that is a plus. I would say this would best used to keep weeds at bay and apply monthly to areas you want to keep clear.

I read in other comments that this weed killer takes 2 to 3 weeks for results. That's true. I used this in 60 degree weather and it took almost 4 weeks. BUT, it did kill them all and has kept the down. I have already purchased another bottle.
