Grain SHIELD® Liquid Mold Inhibitor

Grain SHIELD® - Liquid Mold Inhibitor For High-Moisture Grains

Grain SHIELD® is a liquid grain storage solution registered with the United States Environmental Protection Agency (EPA). Grain SHIELD is a high-moisture grain preservative used to control molds and fungi in stored grains such as oats, corn, barley, wheat and sorghum. Grain SHIELD Liquid contains a minimum of 72 percent propionic acid combined with acetic, benzoic and sorbic acids, all combined to work as a broad-spectrum mold inhibitor for grain.

What organisms are controlled by Grain SHIELD?

Grain SHIELD inhibits the typical wild yeast and mold growth of high-moisture grains during storage and reduces processing costs by eliminating the need for drying grains for storage.

Why is Grain SHIELD EPA-registered?

Products used in the United States as fungal inhibitors for grain are registered with the EPA. Grain treated with EPA-registered fungicides may be marketed after treatment and storage.
