Things You'll Need
- Propionic acid
Instructions
Test the hay before cutting it to see if it is completely dry.
Spray propionic acid over the entire crop to prevent the fungal growth that causes dust.
Cut corn after two to three days of sunshine and dryness to ensure that it is completely dry.
Store harvested hay immediately in a dry, cool and dark area, such as a barn hayloft.
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.
Store batches of hay separately, to ensure that dust in one does not spread mold to the others.
