Would RecommendEasy to use
[This review was collected as part of a promotion.] We were impressed with how simple BioAdvanced Brush Killer concentrate was to use. The directions are straight forward. Mix the clear liquid with water and use a sprayer, which helps control where it gets applied. The mixture sprayed evenly and consistently. We had no issues with it clogging. We didn't notice any super strong odor from it. First application we sprayed lightly, not knowing how strong it would be. Took about 2 weeks for us to not...

Great product works fast!!
[This review was collected as part of a promotion.] This product was amazing and helped clean out an area that I wanted to re-create a flower bed that was grown over by weeds and small trees that had started growing. It didn’t have a strong smell, which was a plus. The next day, I could see a substantial difference. The after just looks amazing.

Works great
[This review was collected as part of a promotion.] I put the killer in this grass that was covered with many roots and poison ivy since it’s been untouched for a long time. The next time I came back to see it, the results were great and I didn’t have to struggle with removing the rest.

Avoid - does not work well.
I followed application instructions to the letter... and it did not kill most weeds and barely killed a few. Avoid this product.
I'm sorry to hear of your disappointment with BioAdvanced Brush Killer Plus. As the product is a selective herbicide that is designed to work sys... Read More

Bye bye poison ivy!
[This review was collected as part of a promotion.] The spray application of this makes it incredibly easy to get rid of any plant life that you don’t wish to have around! The nozzle disperses the right amount of liquid without clogging or dripping down your hand, which is appreciated. It’s super effective!! We live in the country and have a lot of poison ivy and this stuff really made a difference with one single application!! We only used it once and noticed the poison ivy starting to die off....

Got rid of our poison ivy!
[This review was collected as part of a promotion.] We have a very large backyard and we have so much poison ivy and weeds. My dogs always infect me with poison ivy year after year and we have such a hard time eradicating it. We used this product and after about two weeks we didn’t have issues with the poison ivy. I am really really happy with the effectiveness. You need to remember to dilute the product!! You do not want to pour it directly out. I would recommend this product.

Quick acting and effective!!
[This review was collected as part of a promotion.] I have a lot of dense brush and stubborn weeds surrounding a culvert, and this made the job so much easier! I sprayed everything thoroughly, and within a few days I could already see the weeds and brush drying up and dying. It’s definitely strong and effective, even on the thicker growth. The smell wasn’t too overpowering or unpleasant, and I don’t notice and sticky or visible residue after it dried. It dried down nicely and stayed where I spra...

Safe for all of your plants with top notch results
[This review was collected as part of a promotion.] This formula has come in clutch for me this summer. With all of the rain and heat the weeds were out of control till I started to use this. Its not a strong chemical smell it didn't harm my plants and it dried within minutes.

Does what it says, just take time to prep the area properly
[This review was collected as part of a promotion.] Takes a bit to prep the area before use but works well afterwards. Instructions were well written and easy to follow including dilution and safe discard of tools involved. I have used other products that work just as well without as much prep work which is the only reason one star was removed. I used this to remove brush from an area so that I can soon plant a small garden in this area.
