I hate weeds.

Would Recommend

I bought this on clearance at my local Lowe’s store and intend to use it to spot spray weeds in the yard. It couldn’t be any more convenient with the sprayer already attached and the chemical in a RTU (ready to use) concentration. I spray the problem weeds and then wait a few days before mowing.

[This review was collected as part of a promotion.] Application using this product was easy and the product worked as expected. While I didn’t notice a difference over other weed killers I have used in the past- I was happy enough with this one as well.

Excellent weed killer

[This review was collected as part of a promotion.] I’ve been using BioAdvanced Lawn Weed Killer this season and so far, I’m pretty happy with it. It knocked out the dandelions and clover in just a few days, and my grass didn’t seem bothered at all. I like that it’s rainproof quickly, so I don’t have to stress about the weather. Just make sure you read the label carefully… I wouldn’t use it on sensitive grasses like St. Augustine, but for my lawn, it’s been really effective. Overall, a solid we...
