Seriously, too small. Not worth your time or money.Round Up does work though, to be sure the red bottle works well, just be aware you're buying just a tiny amount. Pay attention before check out.

I have used this stuff to kill everything from grass to stubborn weeds that grew out like bushes. This stuff is AWESOME.

This is a concentrate, and you mix what you need and is better than the premix stuff you get at Home Depot or Lowes. That stuff is watered down by law.If you have a co-op you can get a similar product.

what can you say, it's roundup, it kills the weeds where you spray it. have 2 homes, one in FL and one in NC, use it both places and it does the trick. spray it today, weeds are dead the next day.

I liked the fact that I got same price as big box store without having to go there. Delivered the next day

Doesn't seem to kill the roots of the weed as it use to do. I practically drowned the weeds with this stuff, it will burn the leaves and whatever else you you can see above ground but the weeds keep reappearing. Back in the day that wouldn't happen and since it costs nearly 2 times as much as Spectracide it's not the value it once was either.

I liked the fact that this product works. Instead of buying diluted pesticides for around the same price, I ended up buying this and a 1 gallon sprayer. I believe it says 6oz per gallon.I use this to spray the weeds in my yard and mesquite trees that are trying to grow.I haven't used it for long so I can't say much about the mesquite trees. The weeds are dead though so I'm happy.I have used the ready to use Round Up pesticide in the past and they worked on mesquite trees. I'm just going to assume the concentrate will work as well.
