Herbicide after hay cutting?

[dun]

I applied Tordon 22k about 45 days ago which got most of the weeds but I now have a good crop of Horsemint mixed in with the Bermuda. Does any recommend applying herbicide again after the first hay cutting? Or second cutting? (provided you don't go over the max limit of herbicide product for the year) Or should I just not worry about it until next year?

Do you have any plant/wildflower pickers in the area? Up here they will go through a field of horsemint and clean it up.
That aside, I plan on spraying Grazon on a couple of the hay fields in a week or so. We just cut them this week. Late june we;ll probably graze them then stockpile or may cut them for hay again , then stockpile
