Our Thrifty Hoof™ is a proprietary blend of acidic ingredients that kills the heel wart virus on contact. When a young wart lesion is sprayed, the first spray is generally all that is required to eliminate it. For larger, more developed lesions, more than one application will be necessary. This hoof product is the most powerful killing product on the market. Thrifty Hoof™ comes with a sprayer that attaches to the jug, making this product easy and convenient to use in your barn.
