Reseeding pasture in Northeast Pennsylvania? What seed is good?

Our pasture has been lacking so I think it's time to reseed it, We have never done it tho(and we have had horses in there for 13 years!) Anyway, I think now would be a good time to do it because it's a complete muddy torn up mess, so we couldn't even have to dethatch it, they did it for horse from running around like crazy the last few days lol....Anyway What is a good seed to get? I have heard there are trample resistant seeds? Since my horses would be in the pasture while the seeds are sprouting, we have a half acre pasture we can put them in, but there is no shelter or heated buckets if it gets too cold...any ideas?

Ky 31 tall fescue is the absolute best grass for horse paddocks in your area. Do not waste time on anything else - no clover, timothy, orchardgrass, etc. it is cheap and it works. Put down 30lb to the acre

I read an interesting article recently that most grass seeds come coated with an ingredient that basically grows mold or fungus along with the grass. It might be that Penkote thing you see on all the mixes. I wish I could remember where I saw it because the article stressed not having it in pastures and to use a mix that does not contain it. It was probably Equus magazine. If I find it, I'll repost.

Tall Fescue, Ky 31 is an excellent horse pasture forage grass. Tall Fescue does not harbor mold spores, but it is susceptible to root fungus. However, the only time it is of concern is with mares carrying foals. Even then a mare in foal will do fine on Fescue up until the last 3 mos of gestation at which time she should be put up in dry lot. However, I do know of mares who were not drylotted within the 3 month time frame to foaling. The possible complications due to Fescue Fungus for pregnant mares is: The foal will be overly large to pass through the birthing canal, the mare's milk may not drop down for the foal to nurse, the foal's predicted foang date will go far beyond the normal high end of gestation of 340 days.

As for stallions and geldings fungus-infected Tall Fescue causes no problems what so ever.
