Aluminium phosphide is the chemical compound with the empirical formula AlP. Aluminium phosphide is used as a rodenticide, insecticide, and fumigant for stored cereal grains.It is used to kill small verminous mammals such as moles, rabbits, and rodents.
Use as a Fumigant:
Aluminium Phosphide is classified as a hazardous substance and as a dangerous good. Aluminium Phosphide is registered for use as a pesticide and is widely used for fumigating grain and for rabbit control. Aluminium Phosphide is available in solid form (usually as tablets or pellets) and on exposure to air or moisture reacts to generate phosphine gas (PH3). Aluminium Phosphide is the phosphine gas that acts as the fumigant and can be extremely dangerous to you when inhaled.
Use as a Pesticide:
Aluminium Phosphide is used as a rodenticide, Insecticide, and fumigant for stored cereal grains. Aluminium Phosphide is used to kill small verminous mammals such as moles, rabbits, and rodents. The tablets or pellets typically also contain other chemicals that evolve ammonia which helps to reduce the potential for spontaneous ignition or explosion of the phosphine gas.
As a rodenticide, Aluminium Phosphide pellets are provided as a mixture with food for consumption by the rodents. The acid in the digestive system of the rodent reacts with the phosphide to generate the toxic phosphine gas. Other pesticides similar to Aluminium Phosphide are zinc phosphide and calcium phosphide.
