The recipe we've been advising since 1979 for extender patties has
always called for granulated sugar.
It came from a paper by W.T. Wilson, J.R. Elliot and J.L. Lackett.
The wording below may be slightly different.
ANTIBIOTIC EXTENDER PATTIES
(for 2 hives, increase as needed)
1/3 lb solid vegetable shortening
2/3 lb granulated sugar
2 Tablespoons Terramycin 25
Stir the TM 25 and dry sugar into a uniform blend.
Mix the antibiotic/sugar blend with the shortening, without heating.
Yields 1 pound. Divide into two, 1/2 lb patties.
To make handling easier, use a sheet of heavy brown wrapping paper.
Give 1 patty per colony. Place the patty on the paper, on the top bars
of the lower hive body (center of the brood nest).
Remove antibiotic patties before the honeyflow.
In our experience these patties last up to 6 weeks (depends on the
behavior and number of bees) and work well to prevent AFB or
prevent/treat European foulbrood in high risk blueberry pollination
situations.
They don't work in colonies weakened by European foulbrood (the bees
don't mobilize them enough). I wouldn't use them on hives with pollen
traps, because bits of the patty end up in the tray.
If a commercial dough mixer is used to blend the shortening, you'd have
to watch because at some point the mix changes from being slightly
friable, to being sticky smooth (like cake icing, maybe harder to
handle by the scoop.)
Confectioners = icing = powdered sugar is used in a dry mix (1 part TM
25 to 5 parts sugar) with antibiotic, for dusting on the top bars (2
level teaspoons per hive, avoiding the area immediately above brood
cells, to avoid damaging brrod). Granulated sugar would not adher to
the antibiotic powder to make the mix attractive. I understand that some
people powdered a small amount of granulated sugar in a food blender,
either because they didn't have any commercial powdered sugar, or were
concerned about the small amount of powdered starch in the commercial
product.
