Thanks for the info Holly, someone called it a fungus, and I just assumed it was since it is soo tough to clear up.

Rain Rot is not a fungus but a bacteria . . . The most success I've had is from using Iodine-based washes (see my previous post) and by softening and picking off the scabs (which can be quite painful for the horse, so must be done with care and patience) and then soaping the horse up for 3 days with the iodine. The following link has excellent info: http://www.equusite.com/articles/health/healthRainRot.shtml

the sulfur in MTG is probably why i have had such great luck with it......we also use it on our dogs and cats when they have any skin irritations. that and the nu stock creme seems to handle most of what mine can get into. as wet as we are again here----keep those suggestions coming----we could end up with a case of rain rot from **** if this rain keeps on............LOL.

Flax doesn't prevent rain rot. I have fed flax, rice bran and a mix for the past 2 yrs., currently feeding "Horseshine" which I feel is superior to many brands of flax, which must have adequate calcium or will cause problems in the digestive system. The horse with the rain rot has been on these supplements the entire two years. This is a fungus he has had a tiny bit of every year, but with this year's prolonged rainy season (>30 days straight, over 60 days in 3 mos), it got out of hand. We got >25" in 3 mos. Now it is raining again. I hope the cold contains it, and I will treat it again when the rain stops. I cannot keep him up all the time, he gets stall fever and will go nuts. I think the sulfur will work. :D yeah!!!

have to agree w/benefit of ground flax seed----both of my mares get it in their ration and while they both got a light case of RR (we ended a 2 wk stretch of "wet" with 24" of accumulated rain) it cleared right back up with one treatment of MTG and the pastured ones got it worse and took 2-3 treatments. the one gelding that had been on the flax actually had the lightest case as far as the pastured ones went. everyone stay warm and have a great weekend.

I tried the oil/sulphur tx, and after 8-10 tx's. it has helped, but I won't say it's gone. The sores have healed and no hair has fallen out. So I have high hopes!

Just a brief update that the oil and sulphur worked great, with just one treatment.

If you feed an ounce of ground Flax seed a day it promotes a shiny coat and it will prevent the rain rot before it ever start.. This is cheap natural and works great

Wow,, and here I had posted this for a friend ,, and now I went out and noticed 2 of my 3 horses had some rain rot today. I came right in and chose to use the oil and sulphur treatment, as I had those two products on hand. My palomino loved the oil treatment and just relaxed as I soothed it over his back. Time will tell and I will let yall know how this tried and true remedy works! Thanks for all your valuable input!!

Try putting mineral oil on the growths. It works on taking off warts in a couple days, so it could work on the sores.
