I’ve been using Roundup for a long time. I tried this weed killer and it works just fine. Lower cost and kills weeds. I’ll be using this from now on!Thanks!

This is very effective and this brand is all I trust for killing weeds. It doesn’t work right away which turns some people off. Give it a week or so.Note there are two different products. Super concentrate and 365. 365 has a weed preventer in it and shouldn’t be used in the root zone of plants and trees you want to keep. Super concentrate kills weeds roots and all, but doesn’t prevent weeds. No prevention. The prevention additive is Imazapyr which adds to the cost per gallon of mix.Mixing: super concentrate is 2.5 ounces per gallon. 365 7.5 or so ounces per gallon. So as you can see super concentrate gives you a lot more gallons per gallon than 365, but without the up to 1 year weed prevention.So choose wisely and happy… spraying.

I bought this weed killer to kill Bermuda grass! It worked great! It's slow acting like 14 days but it kills it out completely!! I plan on spraying again in another week to make doubly sure it's dead!

I like this product because it is reliable. I have a stream leading out of my pond and I battle weeds along the streambed sides. This product is effective although needs to be applied at least a couple of times a year.

This stuff puts Round-Up to shame and works so much better. Be sure not to use it within 24 hours of an expected rain, or it may not work as well as expected. We've gone through a gallon on our 12 acres of property and purchased another gallon, which should last for a couple years, now that most of the weeds and grass around our perimeter fence are under control.

It is an all green growth killer. Please be careful with the concentration and smell.
