Great weed killer
Would RecommendExcellent product, works great
Hook up, spray, done. That's exactly the experience we designed the hose-end bottle for. Thank you for the five stars!
Doesn’t work
[This review was collected as part of a promotion.] Product did nothing. Sprayed the whole area per the instructions and it did nothing. The weeds are still there. Didn’t kill the grass or anything.

Average results
Have used two bottles in an attempt to kill invading Kudzu. Applied with an Ortho hose end sprayer. Product works slowly and is not totally effective, even after two applications. I will try a different brand.
correction to prior review
Would RecommendMy prior review shows I was disappointed with this product. I am correcting that comment. It just yook a little more time for the product to work. It met all its claims and I am pleased with the results.

It just happened to work out where I only needed the one gallon and I was able to get everything covered.. was amazed with the results and that I was able to get so much covered. Will buy every year forever.

[This review was collected as part of a promotion.] It was easy to apply and instructions were clear. Two weeks after applying to tall woody weeds, only the flower parts had turned brown. I did two applications to a patch of clover in my flower bed and it did nothing. I had to pull them out by hand.

Effective at eliminating overcrowding weeds!
[This review was collected as part of a promotion.] The BioAdvanced Brush Killer Plus had its work cut out for it on my bank! Very overgrown as I tend to clean it up twice a year. This concentrate was easy to mix with clear instructions and is currently battling all my pesky weeds!

Didn’t do much.
[This review was collected as part of a promotion.] The spray works well as far as coverage. However I sprayed poison ivy and a few other things in these pictures without much effect on any of them. It may need to be a bit stronger to do the job.

Excellent! Thank you for sharing your success with BioAdvanced Brush Killer Plus! -Madison
Jury still out
Great on weeds but not shrub roots
Wonderful! Thank you for taking the time to share your success!
Concentrated is best
Would RecommendI was pleased to find a concentrate, since tge premixed products don't work as well and several applications are needed. With the concentrate, I can control the mix, per the directions of course.
We appreciate your review of BioAdvanced Brush Killer Plus! -Madison
Seems to have done well on the ivy. however, it was not effective on the crabgrass growing in my beds.
Thank you for your review of BioAdvanced Brush Killer Plus! While this is a great product, it is not formulated to kill crabgrass. -Madison
