Assuming that you have the TSP (Terramycin Soluble Powder) in the 6.4 oz. package, apply as follows.
Mix 1 oz. of the TSP with 7 oz, of powdered sugar. Feed the bees 2 rounded tablespoons of the mix three times, four to five days apart, for a total 6 tablespoons. This is enough mix to treat two colonies three times each with a little left over.
If you have more hives you can mix the full 6.4 oz. TSP with 2lb, 7oz of powered sugar and feed the bees as described above. This will be enough mix to feed 16 colonies the required three times with a little left over.
If you have the TM-50D or TM-100D let me know and we'll work that out for you.
