Abstract
A phosphine releasing composition suitable for use as a pest control agent comprising a mixture of aluminium phosphide, zinc or a zinc compound and a source of ammonia or ammonium ion, can be produced by mixing the components. The zinc or zinc compound in combination with the ammonia or ammonium ion protects the compositions when exposed to water vapor or liquid water against auto-ignition.
