Fumagilin-B is the only effective treatment for Nosema Disease which stresses over wintered colonies and can reduce honey production by as much as 50%. Due to increasing Nosema Apis and the newly discovered Nosema Ceranae infestations we recommend feeding Fumagilin-B in late fall and early spring to all of your colonies and newly installed packages. Feed two gallons of syrup in late fall and one gallon in the spring. 1/2 gram container makes 5-6 gallons
Although Fumagilin-B is expensive, it will more than pay for itself in increased honey yields and colony vitality.
