Dehydration- Nature’s Oldest Form of Insecticide

It is estimated that up to 50% of all grain grown is damaged by insects. Chemical poisons, often do more harm than good. They must be applied repeatedly, resulting in the formation of a harmful residue. They also may lose their effectiveness as insects build immunity.

D-10 works mechanically to destroy insects. Insects can’t build immunity to D-10, DE is a desiccant, it absorbs the waxy cuticle protecting the insect causing the insect to lose body fluids and die by dehydration. There are no other ingredients in D-10 Grain and Seed Storage Insecticide other than the pure Diatomaceous Earth used in Perma-Guard™ products.

Kansas State University in conjunction with the USDA have attained positive results from testing Diatomaceous Earth. The USDA then stated in the Grain Inspector’s manual that grain proven to include DE as a protectant could not be downgraded.
