The product should be mixed with water to provide a 10% solution for topical application as a footbath (1 lb per gallon, 1 kg per 10 litres of water). Top up the bath if necessary with the same strength solution. The bath should be deep enough to completely cover the feet. The feet of badly affected animals should be trimmed. Sheep should stand in the solution for at least 2 minutes and then be allowed sufficient time for drying before being returned to grass.

All the animals in a group should be treated. Treatment should be repeated in 2 weeks if infection is likely to reappear.
