This NebGuide provides step-by-step instructions for fumigating stored grain on the farm with aluminum phosphide.

Fumigants act on all insect life stages. They control pests by diffusing through the air spaces between grain kernels as well as into the kernel itself. Fumigants are able to penetrate into places that are inaccessible to insecticide sprays or dusts.

Regardless of formulation, all fumigants are poisonous and toxic to humans and other warm-blooded animals as well as to insects and other pests. Because fumigant chemicals are highly toxic and hazardous to use, they are Restricted Use pesticides. They can only be used by certified applicators. This NebGuide is designed to help farmers who have a private pesticide applicator license and want to do the fumigation themselves.
