Field Bee
I bought some Kurtail (after taking out a second mortgage) - yes it kills the stuff it contacts, but new stuff just keeps on coming through, so a few months on and it's the same as before.
I have about a quarter of an acre of wall-to-wall Mares-Tail, and the stuff keeps creeping towards other, clean areas.
What I'm going to try next year is to mark out a section, strim it down to (say) an inch from the ground - then immediately spray that section with Roundup, and hopefully get spray into those cut stalks before they self-heal. Then strim another section, spray, and so on ...
It's the only way I can figure of getting past the waxy coating.

All you need is diesel or something similar mixed in with the roundup and the waxy coat won't be a problem.
