Well this is backwards!

I know folks have used stump killer because of the KNO3 content. Well, I use pharmaceutical grade as i believe better ingredients make better product. however, today, I want to kill stumps. My question is, what concentration of KNO3 is in stump killer? Or. how much 99% KNO3 in a pint of water? Or any variation. I'm thinking that I'd like to end up with about 500ml. I cannot find stump killer around here. Odd. And, nothing to do with this thread but, I just found out that BP is no longer made in the USA. This heavily saddens me. I truly hope it comes back! While I don't like using my ingredients to kill stumps, I do like things that work. On a side note. I've been making BP for almost 20 years and believe I do a pretty darn good job. If your one of those who could use some help, let me know. If you are at a level that you would like to try making pucks, let me know and I'll see about making you a puck die. A truck and bottle jack will work just fine.

I don't know anything about killing stumps but Estes Energetics bought the Goex plant and say they will be making sporting powder by the first of the year.

It's not stump Killer, it's stump remover. Two totally different products. Stump killer is going to be closer to Roundup than BP. Any good grade of herbicide applied to a fresh cut stump will usually do the job.

Remover.

Go look up a product you like, and read the label online. My preferred remover is used directly as granular KNO3, in holes in the stump.

. . . but if I made my own blackpowder, I wouldn't be using bare KNO3 to remove stumps. . .

I have only tried it on a mulberry stump, and the stump is still there (and hard as a rock) three years later, having been treated each one of those years.

Drill 1 inch holes by 12 inches deep Aprox add kno3 to fill hole. Plug said hole. It just helps the rotting. Would not work in a dry area.. One can add diesel to the Kno3 and after soaking it can be burned.

Yes, but if it is a mesquite it may take multiple applications over years and even then it may come back a few years later. Personal experience. Mesquites are hardy, very hardy. My experience with remover has been the same as beag-nut's if not worse.

When it comes to Mesquite I've found the best stump remover is a backhoe.

When conditions are just right, this method works very well.

I drove through Minnesota south of St.Cloud? a few weeks ago. They’re preparing for a four lane highway there and removing all the stumps. My BIL says they cut the tree trunks to about 6 feet tall and then pop them out with a dozer blade, front end loader or tractor with a chain up near the top of the stump. Said they come out easily that way.
