It works

[This review was collected as part of a promotion.] This was great to dry up and remove all the weeds in my backyard, it great to have around. It gets the job done a little goes a long way. I recommend trying it out.

It's my go to

[This review was collected as part of a promotion.] I absolutely love Bio Advanced products. I live out in the country on several acres and this extended control brush killer does what it is supposed to. I use this product regularly and probably will continue to forever.

Worked great!

[This review was collected as part of a promotion.] This brush killer worked great in our backyard. My husband only had to use it once for it to get rid of the area he was working on. We would buy it again and recommend it.
