STOCKMASTER® Sweet Phos 4 Altosid and STOCKMASTER Sweet Mag 14 +TM Altosid are free-choice minerals with Altosid ((S)-Methoprene) insect growth regulator for feed-through fly control.  Feed continuously from thirty days before the last frost in the spring to 30 days after the last frost in the fall to prevent emergence of the adult horn fly from the manure of treated cattle.  These STOCKMASTER formulas are approved by the Environmental Protection Agency (EPA), allowing Hubbard Feeds and its dealers to floor stock and distribute these products where state registrations have been completed.
