What would be the effect if one were to pour acid of some kind down the tube/stem of the plants ?
I've no idea. You could try it and see if it has any effect.

The area affected has no water/walls etc close by btw.
I would follow Radz's method in this case.

Another possibility is to use SBK Brushwood Killer mixed with paraffin and/or old engine oil - but that's just a guess (I use it on ivy which has spread through walls and other persistent weeds such as ground elder). No guarantees.

I forgot to mention that we wear protective gloves - this is as much to prevent contamination of any food or drink that we might need during the treatment.
