Altosid IGR XRB Bolus Feed-Through Fly Control for Cattle

Altosid IGR XRB delivers horn fly control internally with a sustained release bolus. After the bolus is orally administered, it settles into the cow’s rumen where it will dissolve over time, releasing the active ingredient, (S)-methoprene, consistently for up to 195 days. This ensures that cows receive consistent, season-long horn fly control regardless of mineral consumption or location. The active ingredient is then passed through to the cow’s manure where horn flies lay eggs. By disrupting the horn fly life cycle, it effectively prevents the development of pupae into biting adult flies. Altosid IGR XR has no impact on beneficial insects and non-target species.
