Don't misunderstand, I truly believe that the Tricide saved my EE girl from a fairly immediate death. I couldn't find a kernal in the swelling and it was pretty severe. She would have been dead by now from the staph infection if I hadn't found a treatment. It is expensive, though. You can mix it in smaller than gallon batches at 1.5 Tablespoon per half gallon to conserve the powder (weighed and measured by me last fall.)
