    Default Tetracycline

    When treating for efb I've seen dosage should be 200mg per hive. I've also seen 250mg per hive. Which is it? Also when treating a nuc do you only give 100 mg or what? Thanks

    TM50 is still available at the bee suppliers isn't it? Ask them.

    No drug should be fed when
    there is danger of contaminating the honey crop. Fol-
    low the directions carefully and do not overdose. Re-
    member that spores may and often do survive feeding
    of these drugs and colonies may break down with dis-
    ease when treatment is terminated.
    Terramycin Soluble Powder is used for the prevention
    of European and American foulbrood. This product is
    available in a 6.4-oz packet. The package directions
    can be confusing; to determine the correct application
    amounts, follow these directions:
    • The legal dose is 200 mg, three times, at 4–5 day
    intervals.
    • One package contains 10 grams (10,000 mg) of
    Terramycin.
    • 10,000 mg ÷ 200 = 50 treatments per package.
    • 50 treatments ÷ 3 = 17, so one 6.4-oz package treats
    17 colonies three times each.
    The package calls for one teaspoon of Terramycin
    Soluble Powder per ounce of powdered sugar. Use the
    following calculations:
    • One level teaspoon of Terramycin = 200 mg, or one
    treatment.
    • Each 6.4-oz package contains 50 treatments, so mix
    one package with 50 oz (just over 3 lbs) of powdered
    sugar. Store in a tightly sealed container. (Expo-
    sure to air or moisture will break down Terramycin.)
    • The dosage per colony is 2 tablespoons of this mix-
    ture, given three times, 4–5 days apart (for a total of
    600 mg per colony). Spread two tablespoons of the
    Terramycin mixture over the end of the top bars in
    the hive body with the most brood.
    Preventative treatments can be applied to colonies in
    the fall after honey supers are off and again in the
    spring 45 days before putting honey supers on.
    Premixed Terramycin formulations:
    Terra Brood Mix®️ (Mid-Con)
    Tetra Bee Mix®️ (Dadant)
    Terra Patties®️ (Mann Lake)
    Terra Pro®️ (Mann Lake)
    Terra Brood Mix or Tetra Bee Mix. These products are
    identical. This is premixed Terramycin and is used in
    the prevention of American and European Foulbrood.
    It takes the guesswork out of how much Terramycin
    and sugar to mix together. For both products, the dos-
    age is 2 tablespoons, three times, 4–5 days apart.
    Spread the Terramycin mixture over the end of the top
    bars in the hive body with the most brood in it. Treat
    colonies in the fall after honey supers are off and again
    in the spring at least 45 days before putting honey
    supers on.

    This is what I found. I wasn't sure either. Seems like spreading on the face of the combs would be more effective but I guess on the top bars in the way to go?
