One of the mysteries of the English language finally explained.
A colorless foul-smelling gaseous compound of phosphorus and hydrogen, analogous to ammonia, widely used as an insecticidal fumigant in agricultural products.

- ‘The two main alternatives for methyl bromide in pesticides are ‘integrated commodity management’ and fumigation, which uses phosphine and carbon dioxide to kill the pests.’
