Just as good as Roundup for killing weeds. My only complaint is in the instructions I discovered that the 41% and the 53.8% give the same dilution tables. This made me realize that they were describing a 1.5% solution of either 41% or 53.8% which have very different amounts of active ingredients. You should adjust the amount to get the optimal dilution for your application. I also was not prepared for the 3X price increase in the last year.

While I received my order in a timely fashion, as promised, it is truly frustrating that the cost has increased by almost 100% in just the last few years. So much so that I am likely to start making this purchase from the county Co-Op, where it is 1/3 less than what Tractor Supply is charging. Additionally, the local Co-Op has it on the shelf whereas Tractor Supply took it off of their shelves a couple of years ago. That move makes no sense to me, since most Tractor Supplies are located in or in close proximity to local ranching/farming communities. By removing the needed products from the shelves and replacing them with products that someone that lives in a residential area would use, forces the local farmers and ranchers to resort to the local Co-Ops, even if it is a farther drive.
