Easy and Effective Brush Killer

[This review was collected as part of a promotion.] So happy with the results from this brush killer. The application was easy. The spray handle was easy to handle and had a good mist for coverage. I really liked how it had a different settings on the spray nozzle so I could target areas as well as mist other areas. The durability of the container and spray nozzle was good enough to hold up to the work I needed to do. Excellent experience and result.

Easy to use

[This review was collected as part of a promotion.] This is wonderful! The handle is so easy to use. It is electric so you don’t have to squeeze a handle constantly. I used the whole bottle and my hand was not sore at all. II will be buying more of this! Highly recommend if you have a lot of brush.

Not recommended!!!

[This review was collected as part of a promotion.] I would not recommend this BioAdvanced brush killer. I sprayed it on 2 weeds growing between our foundation and house. They are still there. I have given this a few weeks before I did this review.

Great poison ivy killer spray

[This review was collected as part of a promotion.] This spray was very easy to use. It can spray a long distance which is very nice if the poison ivy you are trying to kill is back in the weeds a bit and harder to get to. I sprayed some poison ivy that has started showing up around my house and within just a few minutes the leaves were already starting to wilt. I believe this stuff will work very well to get rid of it and prevent it from returning. I’d definitely recommend trying it if you have...

Simple , clear instruction, easy to apply

[This review was collected as part of a promotion.] Easy application, instructions easy to follow and understand, whichever method chose to use. We used a gallon sprayer, pump tank. Just was able to apply today, it's been raining off and on, so can't vouch for how well it works, as u can see , we have a LOT of " ground" to cover getting rid of this mess. Hope it works, as we was very excited to see that it works on stumps, which we can't get to yet. No real strong odor when mixing or spraying. I...

Following the directions

[This review was collected as part of a promotion.] Well it’s not the best smell but it is super effective. After following the package instructions. It was super easy added to a chemical sprayer and went to town. I layed the product down and a few day I started seeing the brush going down. The duration time I would say about a week and you’ll definitely know where you sprayed.

Doesn't kill weeds or grass

[This review was collected as part of a promotion.] I used this on my driveway to kill weeds and after a day you can't tell that anything was sprayed. Probably works better killing brush ,but it doesn't kill the weeds and grass in my driveway

Not as good as other products

[This review was collected as part of a promotion.] I used this brush killer concentrate on a hill in my yard that tends to get overgrown, on some kudzu and on some brush behind my fence. I was surprised to see how long the brush killer took to work. It took a few days before I actually started seeing things die and it didn’t seem to kill everything. Unfortunately, I think there are better products on the market.

Effective

[This review was collected as part of a promotion.] The product works but can take a while to see results. It was not able to kill everything I tested it on, but was overall effective on small plants. We had rain a day after the first application, so the product was reapplied and in a heavier dose.

This Stuff Really Works

[This review was collected as part of a promotion.] This product works. It took about 4 days to see a difference and by 6 days the bush was dead. See pictures. We would recommend this product especially for hard to kill weeds and bushes.

Does not work

Would Not Recommend

Sprayed it on patches of ground ivy 2 weeks ago. Some areas wilted but not one patch died. I would really lime my money back! Wasted my time and money.

Average Weed Killer

[This review was collected as part of a promotion.] Used this product on a forever growing brush patch in my yard. The product size was great. When applying, the product had a small smell, but not unbearable, and was a little difficult to apply with a manual, cheap plastic sprayer. Would’ve been better if it was an automatic sprayer. The product did slightly kill some of the weeds but they were still tough to pull out and didn’t completely kill them- see the before and after pictures. Honestly I...

Probably pretty good

[This review was collected as part of a promotion.] It killed stuff but not the way I expected. I probably should’ve put in a little more effort and cut everything back first but it definitely killed things

Effective but takes a awhile

[This review was collected as part of a promotion.] When I first received the bottle about a quarter of the contents were spilled in the bag it came in. The seal was not effective at all. The actual product worked fine. It took a couple of weeks for it to work and had to spray down the area twice. But once it worked killed everything effectively.
