Hi Everyone, I did a quick search in the forums, but didn't find this in the first couple of tries, and keep getting sidetracked. Dealing with an awkward patch of knotweed in the intersection of several fences at the corner of 3 properties, I'm interested in trying stem injection, but all I can find are ads for various, somewhat sophisticated injection systems... Anyone have a simple solution (generic kitchen basting syringe for example)? Also trying to determine whether every last cane needs to be injected, or half a dozen per clump suffice to wipe out the root system? Most of the patch has been kept down under a couple of feet high, and can be sprayed, but the stuff in the fence is several feet above my head. I'm planning on glyphosate, but I recall a seminar a few years back where they found although glyphosate worked well initially the regrowth was pretty bad a year out, whereas 2,4-D had much better long term outcome: any thoughts?
