454 Gram Bottle of Fumagilin-B

Nosema is a disease caused by a single cell parasite. Historically, there was one type (Nosema apis) that caused diarrhea in bees that were under stress, typically after long winter confinement with no cleansing flights. Treatment and prevention involved feeding of Fumagilin B in the Spring and Fall. Now another type (Nosema ceranae) appears to be involved in the deaths of some honeybee colonies. Unlike Nosema apis, this new type does not cause diarrhea. Diagnosis requires microscopic examination to determine Nosema spore counts. It is unclear whether treatment of colonies with Fumagilin B is effective in controlling Nosema ceranae. Spore counts change drastically during the year regardless of treatment.


Fumagilin-B powder minimizes the effects of Nosema Disease, a stress related disease of honeybees similar to dysentery. Feeding it can increase honey yields up to 50% and can make a big difference in the hive's ability to make it through stressful northern winters. Due to the cost of Fumagilin B, it is the one most neglected by beekeepers. Neglecting treatment with Fumagilin-B is a serious mistake. Over and over again researchers have found that feeding Fumagilin-B to minimize stress in honeybees will pay for itself in increased production.


Directions: Mix 454 g. bottle with 100 gallons of sugar syrup. For Spring feeding, feed 45 days prior to honey flow. For Fall Feeding, feed after honey supers have been removed. This mixture will treat 100 hives in the Spring or 50 hives in the Fall.


Note: Yellow spots in the snow on warm early Springs days are often caused by normal cleansing flights and do not indicate a Nosema infection.
