[This review was collected as part of a promotion.] I used on my front yard, which had several weeds, I sprayed it, and it dried and killed all the weeds. It works awesome and highly recommend it to everyone.

Didn't do anything noticeable.
[This review was collected as part of a promotion.] I'm not sure what to say about this product. It says to use 4-8oz mixed with a gallon of water. I mixed 4oz with half a gallon. I didnt notice a change other than a little brown grass in the immediate area. Strong chemical smell (which if it worked would be understandable) keep out of reach of children like ALL chemicals!

Effective!
[This review was collected as part of a promotion.] This worked amazingly for me. I have to battle a lot of weeds where I live, and I was able to kill all of the weeds, growing up inside the landscaping rocks.  I’m will be buying more of this because it worked so well.

Poison Ivy stands no chance
[This review was collected as part of a promotion.] Bioadvance extended control works ! We have everything in our back yard but biggest concern is poison ivy. My husband sprayed bioadvance on some weeds and a large poison ivy vine and the following days we did see all shriveling and drying up. None survived and we hope it’s not coming back . Happy with the product

Gets the job done
[This review was collected as part of a promotion.] The Bioadvanced brush killer got the job done and eliminated the unwanted weeds and brush. It was a big bottle that should last you some time. My only concern is the safety of the chemicals. As I am reading more and more about how these products, they can be harmful not only to humans but to animals. I suggest that if you have pets that go outside, do not spray it where they will be laying or giving them the opportunity to lick it. Overall, if...

Highly effective brush killer, just be cautious if you have pets.
[This review was collected as part of a promotion.] The BioAdvanced Extended Control Brush Killer was very effective and worked quickly. It was easy to apply and provided good coverage. The only concern was regarding the safety of my animals, but I ensured to keep them away from the treated area. Overall, it had a manageable odor and delivered great results.

Effective Weed Control
[This review was collected as part of a promotion.] The label says that it begins killing within hours which I guess is technically true. You won’t see anything super noticeable after 24 hours. I saw the weeds begin to noticeably turn yellow after about 3 days. The strength of my solution was in the middle of the guidelines listed on the label. I would by thing again. It definitely works. Curious to see how long it keeps the weeds at bay.

Weeds are Gone!
[This review was collected as part of a promotion.] This brush killer works really great! It takes a little time before it actually kills everything. It took approximately 3 weeks for everything to die. We were impressed with how well it worked. It didn’t have a bad odor to it which was a plus. It was really easy to use.

Amazing product!
[This review was collected as part of a promotion.] This is the best killer of the difficult to eliminate weeds. It will essentially get rid of anything it comes in contact with in your yard, so be careful spraying it on your lawn. The best thing is that it does not grow back so you can breathe easily. This is a targeted weed killer which means one bottle will last you a long time. Handle it with care and read the instructions carefully. An absolute no-brainer.

Seems to do the trick
[This review was collected as part of a promotion.] I’m not a huge fan of chemicals to get rid of overgrown greens but sometimes it’s what you need. Especially for poison ivy which is never fun to deal with. This was rather easy to use and apply and seemed to do the trick. It didn’t 100% get rid of everything and there is still some greens growing back but overall did seem to work. Again, just not a huge fan of using chemicals like this.

Great stuff gets it gone
[This review was collected as part of a promotion.] I recently used the BioAdvanced Extended Control Brush Killer in my yard and I’m glad I did. We had some areas we needed to treat and used this product on those areas. Not only did it remove the areas, I am pretty sure plants won’t be growing back in that area. The only disadvantage is it did kill a few flowers of mine so you have to be careful what you use it on. I would use it again though and recommend it. I received a free sample for my hon...

Seems to be working
[This review was collected as part of a promotion.] I have used the BioAdvanced Extended Control Brush Killer on some poison oak that has been popping up in some of my flower beds and also in the cracks of my driveway and sidewalks. After a couple of days I do see that the poison oak and weeds have turned brown and wilted but I am still getting some weeds. I will treat again after a few more days just to be sure. So far I think it may work for the weeds and hopefully the poison oak

Safe, effective and long-lasting
[This review was collected as part of a promotion.] The BioAdvanced Extended Control Brush Killer was effective in taking out even the nastiest of weeds and brush in the back of my yard. It was easy to apply and didn’t take much to have an impact. 8 weeks later and there’s very little regrowth in the area.

Effective over time
[This review was collected as part of a promotion.] Takes some time but is effective at killing poison, brush and stumps. We haven’t tried it on stumps yet but will be soon. Great value for the product and the effects last some time.
