Phosphine is an attractive fumigant because it is lethal to insects and rodents, but degrades to phosphoric acid, which is non-toxic. As sources of phosphine, for farm use, pellets of aluminium phosphide (AlP), calcium phosphide (Ca 3 P 2), or zinc phosphide (Zn 3 P 2) are used. These phosphides release phosphine upon contact with atmospheric ...
