Disappointed

Bought the Extended Control brush Killer in hopes of eliminating some weeds, grasses, and smaller brush around me home and warehouse. The label stares, "See Results in Minutes". Wasn't really expecting that. But three days later, and I'm not seeing anything. No wilting, no brown leaves. they look like they did before I sprayed. Followed the directions to a Tee. What's up with that? Photos are 3 days after application

It’s my go to

[This review was collected as part of a promotion.] I absolutely love Bio Advanced products. I live out in the country on several acres and this extended control brush killer does what it is supposed to. I use this product regularly and probably will continue to forever.

Worked great!

[This review was collected as part of a promotion.] This brush killer worked great in our backyard. My husband only had to use it once for it to get rid of the area he was working on. We would buy it again and recommend it.

Very effective

[This review was collected as part of a promotion.] This stuff works! We used it in our backyard on some stubborn weeds on the side of our house and within a day or two they were gone. Its a very effective product that I recommend trying if you have stubborn weeds that won't go away.

Works wonders only took one application

[This review was collected as part of a promotion.] Absolutely love it we had a bush at our house that we tried multiple times to kill and this was the only product that worked effectively so it was definitely worth the money. It was simple to apply and the product wasn’t expensive. And it didn’t harm any of the plants by my bush either so I was very happy.

This Stuff Works

[This review was collected as part of a promotion.] I received this product for free in exchange for my honest review. I like this extended control brush killer from BioAdvance. It was easy to use. It did a good job at killing tough to get rid of weeds and brush. They haven't grown back after a few months, so I would recommend it.

Semi effective

[This review was collected as part of a promotion.] Application was easy just make sure everything is working properly. I had a lot of unwanted vines growing up so I sprayed this all over. After a few days they were still thriving while some of it was dead, go figure I covered the entire area.

Poison Ivy’s worst nightmare!

[This review was collected as part of a promotion.] Discovered Poison Ivy, in addition to many other undesirable plants, around my property. Poison Ivy was the first target and it’s done a decent job after one application. I applied it for a second time hoping to wipe out that horrible ivy! Packaging is good; easy to measure with the cap that has the measurements inside, and application is a breeze. All you do is mix the concentrate with water to the desired strength and then apply it. I prefe...
