Glyphosate will be less than effective. It relies on being taken up By the green parts of the plant, mainly leaves of course, and then translocates around the plant when growing fairly vigorously If it’s just a few stumps then there will be minimal movement of the material relative to the job it has to do.
Regrowth could well be a problem but I think the SBK advice is the best in the circumstances, so I would certainly do it. But also dig out the stumps as much as you can. Some nice deep drill holes then filled with the material, never heard of engine oil being used but I guess it keeps it in the right place. In the good old days, when SBK contained something called 245T, closely related to agent orange, we would plug the holes drilled in stumps with, er, ladies sanitary products.
If it’s a big flat stump then holes filled with diesel fuel allowed to soak in and then a bag of charcoal placed on top and lit can do a remarkable job. Take a look on YouTube, plenty of redneck back woodsmen happy to share the art!
