Seems to me the cure would be to not have any expose, barren ground there. Why not solarize the area first with black plastic, water and sun; remove the plastic and put down a healthy, thick layer of wood chips there? Weed seeds fall on wood chips and either don't grow or have shallow rooting systems that are easily pulled up.
Overuse of pastures, not regularly mowing them to keep pasture healthy, etc. can lead to these kinds of weeds, so why not take up a more sustainable pasture management strategy to keep the weeds gone instead of fighting them when they appear?
The suggestion of having other types of herbivores rotating through the pasture can also help keep different species that horses won't eat down. Hair sheep are excellent for this and are a low fuss animal...they eat both graze and browse and they rarely pick around things(they will mow everything and sort what they don't want as they do so, with the unwanted coming out the side of their mouths and the wanted staying in), but if they do pick around, the regular mowing of the pasture will clip them down anyway before they can seed.
Pasture management is going to keep better feed and better soils available for your horses and, in the long run, pay off way more in many ways than the short term solution of poisoning noxious weeds. Those weeds are there for a reason and there's a reason you don't see them in some pastures and you see them in others....some pastures are managed and some are merely used.
