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

It works!, but it takes awhile. It doesn't happen overnight but everything I sprayed is dead. It probably took about a week but I'm happy with the results.

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.

Old style ROUND UP. In stores, you will see something called "round up" but it is a different product. You should use care with this. It increases cancer risk. But I make sure I wear gloves, and long pants. I stand upwind or wait till there is no wind. Spray this on the leaves and it kills most everything. It does not kill through the roots, so you don't have to worry about killing plants that you want to keep.

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.

So i was using roundup 365 for years, finally bought a sprayer and this was my first trial. Do not under estimate the strength and wait 2-3 weeks for results! I double dosed using 2 cups of concentrate for 4 gallons of spray and i can say it indeed will kill the grass where you want it gone, just be careful because its more affective than i was used to! (See photos) Its been about 2 months and the weeds have not come back either.

It works slowly. Spray when the weeds are bigger and it absorbed through the leaves. It took about a week before weeds really started to die, but it killed them all in a massive weed patch.

I use this regularly in my yard and garden beds as I rage constant weed warfare with my neighbors trashy unkempt lawn. She is one of those people who says she believes lawns should be all natural. I think it’s because she is just lazy. I on the other hand do not find value in weeds. This helps me keep her hippie garbage lawn from destroying my award winning lawn.

So I accidentally diluted this the wrong way lol Poured the whole bottle into a gallon sprayer then filled with water. Had no clue what I was doing Gloved up and was very careful with pouring and spraying. I did it on a day that was dry and not windy. I have photos to show - was about 6ft of poison ivy growing up and along my fence line. After two weeks it’s completely dead. Highly recommend this if you have no other alternative and have family with a bad allergy.
