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

I was buying RM43 which is incredible but twice the price. I was really surprised at how good this worked. As with the RM43 it takes a couple days to see results the best being when its warm. Its been one week since spraying and it took everything down that I wanted. Really a great product at a great price!!

This stuff kills weeds fantastic. Way better then store bought, but it takes twice as long to see results.

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.

This works great I used this a few times a year. Kills all the grass and plants so need it to just make sure you watch how much you mix Coverage is great good value for your money

Love this product. It works just like the title says. It Kills All, make sure when you spray it, you want the grass gone!

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.

Perhaps it worked for other types of weeds. Our landscaping guy recommended this to get rid of the weeds but did not work at all. The weeds were green and strong after twice being sprayed.

Super concentrated, works great.
