Fumagillin-B (Fumadil-B)

Fumagillin-B, sold under the trade name Fumadil-B, is an antibiotic historically used to treat Nosema disease in honey bees. It is effective against Nosema apis but less so against Nosema ceranae. Fumagillin-B works by inhibiting spore development within the bee's gut. It is administered in sugar syrup, typically in spring and fall as preventative or treatment. However, Fumagillin-B use is controversial due to concerns about antibiotic resistance and its potential impact on bee gut microbiome. In some regions, its use is restricted or discouraged. Always follow label instructions for mixing and administration. A syringe or measuring device ensures accurate dosage when mixing Fumagillin-B with sugar syrup. Consider local regulations and best practices regarding antibiotic use in beekeeping.
