What can I add to Roundup (Glyphosate) that will kill everything, including broadleaf vines, shrubs, small trees, etc? Something I can buy without a permit/license.

Something with the active ingredient Triclopyr.

I thought glyphosate killed everything?

I use Remedy. ( Triclopyr). It can be slow on small trees and brush like wax myrtle and sparkleberry but will get the job done.
One application has yellowed the buttonweed in lawn pretty good. May not kill it though. It's resilient.

Imazapyr is pretty strong. I think it kills bamboo.

RM43 works great, but it is just round up plus imapazyr, be careful with it around any desirable hardwoods

I use RM-18 from tractor supply. It is basically glyphosate and some other herbicide. Since Roundup no longer has glyphosate in it, I no longer buy it because it is not nearly as effective.

RM-43 also works well, but it sterilizes the soil for a while, so you can’t spray it over desirable tree roots, etc. because it will kill them too.

I sprayed 20 gallons of RM18 yesterday on some fence rows and will spray more today.

Unless you want to treat a large area the paint-on cut vine and brush cutters sold at Gleggs work fine. Just cut off as close to the ground as possible and paint with the poison immediately.

I find that Killzall is very good, seems to kill everything....but it takes a few weeks.

I use 41% glyphosate and it kills everything.
