Anyone thinking of using antibiotic extender patties should either use the commercially available ones, or hold off a bit until a better copy of the EAS "new" recipe is available (I too would like to see it). The recipe recently reported looks too far off the old one , to be real!! The "old" recipe (Wilson, W., J. Elliot and J. Lackett 1979?) I have listed as: 1/3 lb Crisco 2/3 lb granulated sugar 2 Tbl Tablespoons TM 25 Stir antibiotic and sugar into a uniform blend. Mix in the shortening without heating, to make a large patty. Divide mix into 2, 1/2 lb patties. Put each on a 6 x 6 inch sheet of heavy brown wrapping paper. Give 1 patty per colony, on the top bars of the lower hive body. (Other recipes have used liquid veg oil and more sugar) (The recipe reported from notes had only "2 t" (?) antibiotic for 4? patties...much less than the above. I'd have to see a more definite reference before I could believe it) Kerry Clark, Apiculture Specialist B.C. Ministry of Agriculture 1201 103 Ave Dawson Creek B.C.
