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

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.

Nothing kills weeds in Las Vegas except for Killzall

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.

these price hikes are making it hard to justify the upfront costs , works well just use 20-30 ml of non ionic surfactant at around a 50 percent concentration-do not use dish soap- so tired of people parroting false gardening info dish soap will negatively affect this stuff.
