The Perstorp Waspik ProSid MI 700 mold inhibitor has all of the mold-inhibiting properties of propionic acid, but not its corrosiveness and strong odor. The product will quickly and effectively kill all types of yeast and mold, and maintain the nutritional value at a high level. Other advantages over propionic acid include: more secure handling than propionic acid, no ADR-restrictions for transport and storage, less evaporation of the product in the air, and the treated grain smells considerably less.
