Is there a recipe to make a medicinal patty for prevention of foulbrood?

Yes, the ‘terri-patty’ recipe follows here. It’s used for the control of both American and European fouldbrood PLUS aids in the control of trachael mites. Take 1/3 lb. of Crisco, 2/3 lb. of granulated sugar and 2 tablespoons of terramycin. Mix well. Make four 1/4 lb. patties. Put patties on 7 X 7 inch newspaper or waxed paper. Put paper with patties between the two brood chambers on top of the top bars. We recommend 1/2 lb. per colony per year.
