Silo Fillers Disease, caused by nitrogen dioxide, was discussed in a joint Agronomy and Pharmacology release. Dr. Mark Luckens, College of Pharmacy, has prepared strips of potassium iodide - starch test paper to assist in detecting this deadly gas in silos and feeding areas. These strips are small (5/8" x - 2") and change to a blue color when in contact with nitrogen dioxide. We have 300 strips available for use by County Agents.
