Fumagilin -B

Fumagilin-B may be dissolved in water or syrup at room temperature. For best results, heat required amount of water to 95-122oF (35-50oC), (1)-remove from heat source and (2)-add Fumagilin-B and (3)-sugar in that order. Good agitation is essential to assure uniform distribution of medicament.
   • To prepare medicated syrup: (2:1 sugar-water [DLW])
To Make 1 gal syrup: Use 1/2 gal water, 1 rounded teaspoon Fumagilin-B, 8 lb. sugar, treats 1 hive.

Timing of Treatment:
FALL DOSAGE - For the protection of wintering colonies, medicated syrup is best fed in the fall if fed only once per year. There may be advantages to feeding in fall and spring. After all honey supers have been removed, feed at following rates.
a) 2 gallons of medicated syrup for each 2-chamber colony (approx 30,000 bees).
b) 1 gallon for each 1-chamber colony (approx 18,000 bees).
c) 3/4 gallon for each 5-frame colony (approx 8,000 bees).
   • Feed additional un-medicated syrup to desired colony weight for wintering .
   • Feed as late as possible in fall. Get syrup into bees before they go into a tight cluster and can no longer take down the syrup.

SPRING DOSAGE - In spring when colonies are stressed due to inclement weather conditions, mite infestations, other disease factors or intensive spring management, additional control may be needed. Medicated syrup must not be fed immediately before or during honey flow.  Feed medicated syrup at following rates.
a) 1 gallon for each package colony .
b) 1 gallon for each 2-chamber colony (approx 20,000 bees).
c) 1/2 gallon for each 1-chamber colony (approx 12,000 bees).
d) 1/2 gallon for each 5-frame colony (approx 8,000 bees).
   • Feed additional un-medicated syrup to provide nourishment until nectar is available.
   • Package bees may have been fed medicated syrup in transit, but such feeding alone is not sufficient to protect against Nosema. Each package is best fed Fumagilin-BR immediately after installation.
