Would Not RecommendThis was a very disappointing purchase. First round, I did the 8oz mix and even a little more to be sure. 4 days later, with no rain and mostly sunny, a few things started to show signs of wilt. Hit the same area with the rest of the bottle, yep - mixed it very strong, and added water to take it to the gallon marker on the sprayer, per directions. 3 days later and one weed and a small crabgrass in a gap on the concrete was somewhat brown. Nothing at all was dead. Sprayed some sort of ivy that ha...
Effective and easy to use
[This review was collected as part of a promotion.] Our backyard is a bit of a jungle, overrun by weeds and vines that seem to take over everything else. I received a sample of the Bioadvanced Brush Killer Plus to try, and I had plenty of weeds to try it on. The bottle has a built in sprayer, and it was very easy to use. Within a few days of spraying it, I could already see the vines and even some of the bigger problem plants drying up and dying. I am very impressed with how easy it was to u...

Not killing bittersweet
Would Not RecommendI bought this to spray a huge bittersweet after it was cut down. I applied it to the cut points over several days. I do not see any signs of wilting. The brush was removed and product applied to cut stems left. Also along ground where bittersweet was spreading …

Fabulous! We are thrilled to hear of your success with BioAdvanced Brush Killer Plus! Thank you for your review!
Great first results.
[This review was collected as part of a promotion.] We applied the BioAdvances brush killer plus as instructed. We have seen areas that are definitely dying off. We are hoping as the summer progresses we will see less of the unwanted weeds. The sprayer works well, no drips and we could target the product where we wanted. Will continue to use.

Didn't work for me
[This review was collected as part of a promotion.] I was hoping it would work for this mess, but unfortunately, after spraying it 3 times and waiting for it to die, I ended up just having to cut it down. Maybe it was the wrong kind of "brush," but it didn't even kill a single leaf. I will try it in another area of my yard, but this is where is is needed since it grows between 2 fences.
