What will kill Mares Tail? Glyphosate is not putting a dent in it in a fence row.

It was just a fence row.With all due respect I submit you may be attempting to treat the sympton (Mare's Tail) and not the condition that allows them to thrive unabated.
Is the ground subject to being grazed for long periods of time, as in continually for so long as one can see green? Mare's Tail is a 2nd year weed
prone to showing up around 2 years after the ground has been disturbed. Hemp would fall in this category, with button weeds being a 1st year
problem, if you have a seed base in the area discussed. Glysophate and 2-4D will work until enough seed stock survives to gain imunity.
Also the weed spray will decimate any chance of what good forbs you may have of surviving. Those more knowledgeable may be able to advise
you on this situation. I would suggest a good fertilizer program, frost seeding some clover or what grows good in your area and then when it
gets to appropriate height graze hard (as in MIG) for 3 days, pull off for 5 to 6 weeks then repeat. At least do this or something similar on a
portion until you come up with a solution that works for you. I realize this is a program requiring movement of stock more than you are accustomed.
Anyway if the spray doesn't pan out there is more than one way to skin a cat!
