Kill honeysuckle and buckthorn with herbicides

Concentrated herbicides are used by many on cut stumps. To kill the stump you need to use minimum 20% Roundup or probably 30% of the generic brands of glysophate and you need to apply it fairly liberally within a minute of cutting it. For large stumps, you only need to soak the area next to the bark, not the hard woody part in the center. Have a brush with you to sweep the sawdust off before applying. The concentrated stuff is a thick liquid and doesn't go very far, you can expect to use 1- 3 dollars worth per stump depending on size.
The high cost of these concentrated herbicides is another reason to use the honeysuckle popper. After about 50 bushes, you've paid for it!
Spraying the leaves of mature honeysuckle bushes with herbicides requires specialized equipment, is expensive, and in my opinion should only be done by profesionals. Plus, spraying doesn't 'remove' them as some claim, it just kills them. You still have all the dead honeysuckle skeletons to deal with. They don't just disappear. The dead stems last at least 5 years and will hinder your follow-up restoration efforts.

  Honeysuckle Popper verses herbicides;
Foreword; I'm not a botanist, scientist or anything like that. I'm a toolmaker thats spent way, WAY to much time learning about and removing bushes.

You dont need one or the other- YOU NEED BOTH

I'm not in competition with herbicides or any other method as "THE" way to get rid of invasive bushes. There is no single 'good' way and no matter how you approach it, its gonna be hard work. The Popper is simply an additional and very effective tool to include in your removal efforts.
From my extensive observations, I can say a typical infestation will have a wide range of ages and sizes. Where the popper really shines is in getting all the smaller ones out of the way, before going in with herbicides (or whatever) to takle the big ones.
Most bushes up to 10 years old pop out fairly easily and the main advantage is that it removes the stumps. This is a great benefit because it eliminates the tripping hazard. The smaller stumps quickly get hidden by the new vegetation and they last 5 years or longer, so its better to get them out of the way. For other advantages CLICK HERE
