How to Prevent Dusty Hay
- 1). Test the hay before cutting it to see if it is completely dry.
- 2). Spray propionic acid over the entire crop to prevent the fungal growth that causes dust.
- 3). Cut corn after two to three days of sunshine and dryness to ensure that it is completely dry.
- 4). Store harvested hay immediately in a dry, cool and dark area, such as a barn hayloft.
- 5). Check the middle of purchased bales of hay to ensure that it is dry completely through. Moisture in the middle of a bale can cause dust.
- 6). Store batches of hay separately, to ensure that dust in one does not spread mold to the others.
