Someone suggested Tea Tree oil, wow does it work great and since 7 out of our 12 Horse get Rain Rot easily we are not going broke, I believe the Tea Tree oil is 8.00 a bottle and one bottle make about 2 gallons of spray.
I heard Betadine, Scarlet Oil and Hydrogen Peroxide were also pretty good, anyone use any of the aforementioned products or have some more economical suggestions?
