Hi-Yield (33691) Super Concentrate Killzall Weed & Grass Killer (16 oz)

I compared this product with other brands, and the difference was clear who's the winner. After I applied the grass killer, in two days I started to see the results. The grass are dying. I also applied on some tree roots, hopefully this will do the trick too.

Tske a few days to see results but it kills everything. Cleardled my ditches and overgrown areas so well. Be cautious if you get on shoes you will sread it while walking. very powerful.

It's gotten harder to find herbicides that actually work since Roundup quit using glyphosate. I'm grateful to find a brand that still does. It's easy to mix, contains the necessary surfactant as well as glyphosate, and works great. This big gallon jug lasts a long time and is a lot more economical than Roundup was when it still worked.

Kills every thing and it stays dead for for a very long time

I can't really rate this because I have not been able to use it.

If you buy this in an hardware store it can run as high as $130. This concentrated weed killer is the best weed killer I have found. It must be applied at least every 3-4 weeks.

this is an excellent weed killer hopefully they won't come back very easy to use with a pump sprayer the weed killer you can purchase in the box stores is nothing compared to this treatment

This weed and grass killer works pretty well at killing a lot of different weeds. It does seem to take a bit longer for it to work but when it does take off working at killing the weeds and grass in areas you put it You won't have to use the spray again for months.

It takes longer to see the effects than they claim, but other than that it works good.

Mixed more than 5 oz. with 2 gallons of water in my sprayer and sprayed many different types of weeds at 85° F. After 4 days nothing has died.
